Why did a T-SQL script fail to run a job when it could
successfully run in SQL Server Management Studio ?
Answer
This issue is usually caused by the fact that the execution security context of the
job is different from the security context when you manually run the script in
SSMS. The commands in SQL Server Management Studio are executed as the
current login. However by default every job step runs in the security context of
SQL Server Agent Service account. If the SQL Server Agent Service account is
different from the login account and if it does not have enough permission to
execute the query, the job will fail.
Though you can simply give the SQL Server Agent Service account permissions to
execute the query, this is not the best way from a security perspective. For SQL
Server Agent Service account, it is recommended to give it the least amount of
privileges. You cannot create a SQL Server Agent proxy to execute the job
because for T-SQL job step it will not use any SQL Server Agent proxy.
For a Transact-SQL job step, by default it runs under the security context of the
job owner and if the owner of the job is a member of the sysadmin fixed server
role, it runs under the SQL Server Agent service account.
You can use one of the following three methods to resolve this issue:
1. The first method to resolve this issue is to change the job owner to a login
who has enough permission to execute the T-SQL script but the job owner
should not be a sysadmin.
2. The second method is specifying the "Run as User" option for the
Transact-SQL job step in case you have several job steps and you do not
want to change the job owner so as not to impact other job steps execution.
You can go to the Advanced options of the job step, and input an user to the
"Run as User" field. Ensure you are a sysadmin to edit this option.
3. The third method is that you can add an EXECUTE AS statement ahead of
your T-SQL script.
For example:
EXECUTE AS USER='user_test';
--The statement will be executed under the user_test security context.
SELECT * FROM MyTable;
--After execute the REVERT statement, the security context will be
reset to the default security context.
REVERT;

7
You can run SQL Server Profiler to monitor which security context is being used
by your SQL job.

How can I degrade a SQL Server database from a higher
version to a lower one?
Answer
Yes, degrading a SQL Server database is not supported, but you can use a flexible
workaround to resolve this issue. You can use SQL Server Management Studio to
first generate scripts for a lower version and then use Data Import/Export Wizard
to transfer data. For example, if you want to degrade a SQL Server 2008 database
to SQL Server 2005, you can follow the steps below:
1. Open the SQL Server 2008 database in SQL Server Management Studio 2008.
2. Right click the database name in the Object Explorer and select "Tasks
Generate Scripts…"
3. In the Script Wizard dialog box, select the database name and check "Script
all objects in the select database". Then click "Next".
4. Set the "Script for server version" option as SQL Server 2005.
5. Run the script in SQL Server 2005.
6. Import data from SQL Server 2008 to SQL Server 2005 by using the SQL
Server Import and Export Wizard.
Similarly, you can do this in SQL Server 2005 Management Studio if you want to
degrade a SQL Server 2005 database to a SQL Server 2000.

How can I create a linked server to the Access or Excel data
source from the 64-bit version of SQL Server 2005/2008?
Answer
Before Microsoft releases the 64-bit ACE 12.0, you can only use the 32-bit
Microsoft.Jet.OLEDB.4.0 to access Microsoft Access and Excel files. The method
requires that you first install a 32-bit SQL Server instance on your 64-bit
environment as a medium, then create a linked server with
Microsoft.Jet.OLEDB.4.0 provider to your Excel/Access file on your 32-bit SQL
Server instance, and then create a linked server to your SQL Server Express
instance on your 64-bit SQL Server instance.
Now you can use the 64-bit ACE driver for the data access. Here are the detailed
steps:
1. Download and install the 64-bit ACE driver.
2. Open SQL Server Management Studio (SSMS), connect to your 64-bit SQL
Server instance and create a linked server to your Access database with the
following T-SQL statements:
EXEC sp_addlinkedserver
@server=N'MYACCESS',
@srvproduct=N'Access',
@provider=N'Microsoft.ACE.OLEDB.12.0',
@datasrc=N'D:AccessDatatest.mdb'
go
EXEC sp_addlinkedsrvlogin
@rmtsrvname=N'MYACCESS',
@useself=N'True'
GO
If you are accessing an Excel file, you need to additionally specify the
@provstr parameter:
@server=N'MYEXCEL',
@srvproduct=N'EXCEL',
@provider=N'Microsoft.ACE.OLEDB.12.0',
@datasrc=N'D:AccessDatatest.xlsx',
@provstr=N'Excel 12.0'
go
EXEC sp_addlinkedsrvlogin
@rmtsrvname=N'MYEXCEL',

10
@useself=N'True'
GO
3. Then you can query with the linked server.
--For query to Access
SELECT * FROM MYACCESS...Tasks
--For query to Excel
SELECT * FROM MYEXCEL...[Books$]

Why is all of the memory allocated for SQL Server not
shown in Windows Task Manager?
Answer
In Windows Server 2000/2003 Task Manager, the" Mem Usage" column shows
the amount of memory for the working se t. The working set of a process is the
set of pages in the virtual address space of the process that are currently
resident in physical memory. Memory allocations that are nonpageable such as
Address Windowing Extensions (AWE) or large page allocations are not included
in the working set. Therefore, if the AWE mechanism is enabled, the Task
Manager will show the memory usage incorrectly. To find out how much
memory SQL Server has allocated through the AWE mechanism, you can use the
sys.dm_os_memory_clerks DMV as follows:
SELECT
SUM(awe_allocated_kb) / 1024 as [AWE allocated, Mb]
FROM
sys.dm_os_memory_clerks
For Windows Server 2008, this column is called "Memory (Private Working Set)"
in Task Manager. The private working set is a subset of the working set that
specifically indicates the total amount of memory allocated by a process, not
including memory shard with other processes. You can roughly estimate the
amount of memory that is paged out per process by subtracting the value of
Process: Working Set from the Process: Private Bytes counters by using the
System Monitor.
1. To monitor overall memory usage for SQL Server, you can run the DBCC
MEMORYSTATUS command. The DBCC MEMORYSTATUS command provides
a snapshot of the current memory status of Microsoft SQL Server. In the
result of the DBCC MEMORYSTATUS command, the Memory Manager
section shows overall memory consumption by SQL Server. The elements in
this section are the following:
a) VM Reserved: This value shows the overall amount of virtual address
space (VAS) that SQL Server has reserved.
b) VM Committed: This value shows the overall amount of VAS that SQL
Server has committed. VAS that is committed has been associated with
physical memory.
c) AWE Allocated: This value shows the overall amount of memory that is
allocated through the AWE mechanism on the 32-bit version of SQL
Server. Or, this value shows the overall amount of memory that locked
pages consume on the 64-bit version of the product.

12
d) Reserved Memory: This value shows the memory that is reserved for the
dedicated administrator connection (DAC).
e) Reserved Memory In Use: This value shows the reserved memory that is
being used.
The following example is the result of the Memory Manager section:
Memory Manager KB
------------------------------ --------------------
VM Reserved 1761400
VM Committed 1663556
AWE Allocated 0
Reserved Memory 1024
Reserved Memory In Use 0
2. In SQL Server 2008, you can obtain this information simply by querying the
sys.dm_os_process_memory DMV. The physical_memory_in_use column
indicates total memory usage of the server including allocation through large
page and AWE APIs. The large_page_allocations_kb and
locked_pages_allocations_kb columns show the amount of memory
allocated using large page and AWE APIs, respectively.

How do I configure SQL Server to use larger memory space
over 2GB on a 32-bit server?
Answer
There are many ways to have your SQL Server occupy more than 2GB memory on
your server.
/3GB
A 32-bit machine can directly address only 4 GB of memory, and by default,
Windows itself reserves the top 2 GB of address space for its own use, which
leaves only 2 GB as the maximum size of the VAS (virtual address space) for any
application, such as SQL Server. You can increase this by enabling a /3GB flag in
the system's Boot.ini file, which allows applications to have a VAS of up to 3 GB.
Note that VAS is just the set of all possible addresses rather than the physical
memory.
PAE (Physical Address Extension)
PAE is the added ability of the IA32 processor to address more than 4GB of
physical memory. To enable PAE, use the /PAE switch in your system's boot.ini
file.
AWE (Address Windowing Extensions)
AWE extends the capabilities of applications running on 32-bit operating systems
by allowing access to available physical memory in excess of the limits set on
their configured virtual memory address space. The advantage is that SQL Server
2005 supports dynamic allocation of AWE mapped memory. If fewer resources
are required, SQL Server can return AWE mapped memory to the operating
system for use by other processes or applications. Also, dynamic AWE mapped
memory is supported on servers with less physical memory than the configured
limit on virtual memory address space. However, on a 64-bit platform, the AWE
Enabled configuration option is present, but its setting is ignored.
Note
1. Enabling PAE is a requirement for AWE memory access above 4 GB. Without
/PAE switch, AWE cannot reserve memory in excess of 4 GB.
2. When the /3GB switch is used in conjunction with the /PAE switch, the OS
does not use any memory in excess of 16GB. This is caused by kernel virtual
memory space considerations. If the system restarts with the /3GB switch in
boot.ini, and the system has more than 16GB available (physical memory),
the additional RAM is not used by the OS. Restarting without the /3GB
switch enables use of all the physical memory.

14
You can refer to the following articles for detail information to configure your
SQL Server to use more than 2GB physical memory.

How do I rename my SQL Server instance?
Answer
SQL Server doesn't support renaming the instance name directly. To work around
the issue, you could use one of the following workarounds:
a) Uninstall the existed instance and install it with the new name.
b) Change the computer name and rename the part of the instance name that
corresponds to the computer name.
For example, you can change a computer named MB1 that hosts an instance
of SQL Server named Instance1 to another name, such as MB2. However, the
instance part of the name, Instance1, will remain unchanged. In this example,
the ComputerNameInstanceName would be changed from
MB1Instance1 to MB2Instance1.
For a renamed default instance, run the following procedures:
sp_dropserver <old_name>;
GO
sp_addserver <new_name>, local;
GO
For a renamed named instance, run the following procedures:
sp_dropserver <old_nameinstancename>
GO
sp_addserver <new_nameinstancename>, local
GO

How do I store data in multiple languages within one
database?
Answer
The easiest way to manage character data in international databases is to always
use the Unicode nchar, nvarchar, and nvarchar(max) data types, instead of their
non-Unicode equivalents, char, varchar, and text. Unicode is a standard for
mapping code points to characters. Since it is designed to cover all the characters
of all the languages of the world, there is no need for different code pages to
handle different sets of characters.

How do I calculate the space a nullable column takes in SQL
Server 2008?
Answer
Scenario 1: The table without SPARSE column(s)
a) Fixed length column needs the full apace of data type even if the value of
the column is NULL or empty.
b) Variable length column needs 2 bytes overhead additional for storing the
data even for NULL or empty.
Scenario 2: The table with SPARSE column(s)
This scenario, is different from the one above. The values of all SPARSE columns
will store together into a complex structure, which is called “Sparse Vector”. It
will take
4 byte header + a list of columns which values are not null + a list of column
offset + real data
For each non NULL value in a row, there will be 2 bytes for the id of the column
in the “column list” and 2 bytes for the “offset” of that column in the real data.
This means, the non null value for a SPARSE column will take 4 + data size to
store, and the NULL value for a SPARSE column will take 0 bytes to store. If all the
columns in a row are NULL, the “SPARSE Vector” will be empty, and it will take 0
bytes.
For other nullable column(s), please refer to scenario 1.
For those non-sparse column, SQL Server uses NULL bitmap to indicate whether
the value of a column is NULL. One NULL value of a column will take 1 bit in the
NULL bitmap, so the size of the bitmap is (the number of column)/8, not
including SPARSE column(s).

This issue is due to not having VIEW DEFINITION permission on the specific
object (database, table, view etc.)
To resolve this issue, you need to grant VIEW DEFINITION permission on the
object to the user which is mapped to the login you used. You can perform this
by running the following Transact-SQL statement:
USE database_name;
GO
GRANT VIEW DEFINITION ON [object_name] TO
[database_user/database_role]

Why can't I by pass the "Restart computer" rule when
installing SQL Server 2008?
Answer
This issue is usually caused by another application installation not correctly
renaming or deleting the registry entry PendingFileRenameOperations.
You can work around this issue by following these steps:
1. Open Registry Editor. Click Start --> Run, input "regedit" and press Enter.
2. Go to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession
Manager, and delete any value in "PendingFileRenameOperations" key.

Can SQL Server Enterprise Edition be installed on client
operating systems?
Answer
In previous releases of SQL Server, such as SQL Server 2005 or earlier versions,
the setup would be blocked on client operating systems. It is no longer blocked
since the SQL Server 2008 release, but it is still not a support configuration.
I recommend that you install SQL Server Developer Edition which has identical
functionalities as Enterprise Edition on your client OS.

How do I troubleshoot SQL Server connectivity issues?
Answer
You may encounter the problem that you cannot connect to your SQL Server
instance remotely. You can refer to the following common practices to
troubleshoot this issue:
1. Check your SQL Server Error log to make sure that it enables TCP/IP protocol
and establish the listening on a specific TCP port.
Normally, if SQL Server is configured to enable TCP/IP protocol, when it
starts it will log a message similar to the following error log:
2010-01-04 12:30:40.47 Server Server is listening on [ 'any' <ipv4> 1433].
This means that the SQL Server instance is using TCP/IP protocol and
listening on the TCP port 1433.
2. Enable TCP/IP protocol if you could not find the message in the Error Log.
You can enable protocols via SQL Server Configuration Manager. Under SQL
Server Network Configuration->Protocols for <instance name>, enable
TCP/IP protocol.
3. Check Network issue after TCP/IP enabled.
To check if your network is healthy, you can use ping and telnet orders to
check.
· Run "ping -t" for 1-2 minutes to check if there any timeout response
ping -t <the remote server IP address>
If there are timeout responses, contact your network administrator to
check the network issue.
· Run "telnet" command directly to the TCP port on the server to check if
you can access the TCP port.
Telnet <servername> <listening tcp port>
4. Check firewall if you cannot telnet to the specific TCP port.
Ensure that the TCP port on which SQL Server is listening has been put into
the exceptions of your firewall. If you connect to a named instance, it is also
recommended that you put the UDP port 1434 for SQL Server Browser
service into your firewall exception.
The connection issues may be due to other causes like client drivers, application
configuration, authentication and ect.

Why can’t I track data changes even though I already
enabled the database audit on my database?
Answer
Database Audit does not track data changes. To track the data changes, you need
to use another feature named "Change Data Capture" (CDC).
SQL Server Audit
SQL Server Audit is used to track and log events (not data change) occurring on
the SQL Server. SQL Server uses extended events to help create an audit. The
audit can be server level or database level. You can refer to the following articles
to create the server and database level audit:
Creating and Managing Audits with SQL Server Management Studio
http://msdn.microsoft.com/en-us/library/cc280500.aspx
Creating and Managing Audits with Transact-SQL
If you create an audit on a database table, SQL Server will only track the events
that trigger the certain operations (SELECT/INSERT/UPDATE/DELETE) defined in
the database audit specification. It also checks the principles defined in the
database audit specification. If the operations are not executed by the defined
principles, it will not log the audits.
You can read the Windows event logs by using the Event Viewer utility in
Windows. For file targets, you can use either the Log File Viewer in SQL Server
Management Studio or the fn_get_audit_file function to read the target file.
Change Data Capture
Change Data Capture (CDC) is used to track the changed data caused by common
DML operations (INSERT/UPDATE/DEKLETE). The capture process reads the
transaction log to pull out the data change information and then load the
information into the associated change table. You can use the function
fn_cdc_get_all_changes_<capture instance name> to query the change data
information.

How do I use Powershell script to read the information of
any database on a server?
Answer
To read the information of a database, you can first grant the VIEW ANY
DEFINITION permission to the current login.
VIEW ANY DEFINITION is at server scope. For example:
GRANT VIEW ANY DEFINITION TO test
Go
Then you can read a database information with the Powershell script like the
following:
$srvname="localhost"
$dbname="Test"
$mySrvConn = new-object
Microsoft.SqlServer.Management.Common.ServerConnection
$mySrvConn.ServerInstance=$srvname
$mySrvConn.LoginSecure = $false
$mySrvConn.Login = "test"
$mySrvConn.Password = "xxxxxx"
$srv = new-object
Microsoft.SqlServer.Management.SMO.Server($mySrvConn)
$db = $srv.Databases[$dbname]
$db.logfiles|measure-object -property size -sum
$logsize = ($db.logfiles|measure-object -property Size -sum).Sum/1024
$datasize = $db.Size - $logsize
write-host "log size:" $logsize
write-host "data size:" $datasize
$srv.ConnectionContext.Disconnect()

Why can't I log on to SQL Server using Windows
Authentication in SQL Server Management Studio?
Answer
If you want to log on to the server using Windows Authentication, ensure that
the current Windows account has been added to server logins. To check whether
the current Windows account has been added, please run the following
Transact-SQL statement:
SELECT loginname FROM sys.syslogins
If the current Windows account is not listed, you need to add the current
Windows account to server logins. You can log on to SQL Server instance using a
system administrator account and then run the following Transact-SQL
statement:
CREATE LOGIN [Computer_NameLocal_Windows_Account_Name]
FROM WINDOWS WITH DEFAULT_DATABASE=[master]
GO
You can also perform this in GUI via Management Studio, in Object Explorer,
server node --> Security --> Logins, right click Logins, select New Login.

What permission(s) do I need to execute a stored
procedure (sp)?
Answer
I already have EXECUTE permission on a stored procedure, but sometimes when
executing the stored procedure, it fails with a permission error. Look at the
following test environment:
Database:
TestDatbase
Users:
user1 (mapped to the login "login1" );
user2 (mapped to the login "login2");
Schemas:
user1 (owned by user1);
user2 (owned by user2);
Tables:
User1.Table1;
User2.Table2;
Procedures:
CREATE PROCEDURE user1.uspGetTable1
AS
SELECT * FROM user1.Table1;
CREATE PROCEDURE user1.uspGetTable2
AS
SELECT * FROM user2.Table2;
Log on to the server with 'login1', run the procedures, you can successfully run
the user1.uspGetUsers1 procedure, but when you run the user1.uspGetUsers2
procedure, you get the following error message:
Msg 229, Level 14, State 5, Procedure uspGetUsers2, Line 3
The SELECT permission was denied on the object 'Table2', database
'TestDatabase', schema 'user2'.
This issue is related to ownership chains. Since the owner of the stored
procedure is different from the owner of the table user2.Table2, SQL Server will
check the permission when the SELECT statement is executed on the table

26
user2.Table2. For the stored procedure user1.uspGetTable1, since its owner is
same as user1.Table1, SQL Server will not perform permission check when the
SELECT statement is executed on the table.
So in this case, to execute the stored procedure user1.uspGetTable2, we not only
need the EXECUTE permission on the stored procedure but also needs SELECT
permission on the table user2.Table2.

How do I troubleshoot SQL Server 2008 installation issues?
Answer
Here are basic steps to troubleshoot SQL Server 2008 installation issues.
1. Check Windows System and Application event logs for error information
according to the time of occurrence. If you are in a cluster environment, you
may also need to collect the cluster log for view (By default the cluster log is
located at C:WinNTClusterCluster.log).
2. Check the SQL Server setup logs, starting from the Summary.txt file. Get it
from %ProgramFiles%Microsoft SQL Server100Setup BootstrapLog by
default. Look up the error message in Summary.txt.
3. If there is not enough information in the Summary.txt, then drill down to the
detailed log file that it mentioned. Check the error code and error message
for detailed information. If you cannot understand the error code and error
message, you can research the error code from internet.
4. If it is difficult to identify the root cause of the issue, you can post a new
thread in this forum or contact Microsoft Customer Support Services (CSS).
Besides if you encounter the common asked questions regarding "Unable to
install Windows Installer MSP file.", you can refer to the following two blogs for
troubleshooting the issues：

How do I configure SQL Server to enable distributed
transactions via Linked Server?
Answer
To enable distributed transactions across different servers, you need to configure
MS DTC on both servers and some of your SQL Server server options. The
following is a list you need to check:
1. DTC service is running
please run "services.msc" from windows run dialog to check if it is running. If
it is stopped, please start it by right-clicking on it and choose "Start".
2. Network DTC access is enabled
if you are using Windows Server 2003, please refer to this link:
if you are using Windows Vista or higher version of Windows, please refer to
this link:
http://technet.microsoft.com/en-us/library/cc753510%28WS.10%29.aspx
3. DTC service is configured to be allowed to access network in firewall
in the linking server, please make sure this service could access the network
and could receive connection from other server. In the linked server, please
make sure this service could receive connection from other server.
4. XACT_ABORT is enabled
we could enable XACT_ABORT with the following statement:
SET XACT_ABORT ON
5. "Ad Hoc Distributed Queries" is enabled
please execute the status of "Ad Hoc Distributed Queries":
sp_configure 'show advanced options', 1
reconfigure
GO
sp_configure 'Ad Hoc Distributed Queries'
if the value under run_value is 0, please execute the following script
to enable it:
sp_configure 'show advanced options', 1

How do I find the correct "server" or "data source" value
for an SQL Server instance in a connection string?
Answer
To get the server value of a SQL Server instance, the first thing you need to do is
to find the instance name. To find the instance name of a SQL Server instance,
please follow the steps below:
1. Open SQL Server Configuration Manager (SSCM) from Start - > All Programs ->
Microsoft SQL Server 2005/2008/2008 R2 -> Configuration Tools;
2. In the SSCM, click SQL Server Services under SQL Server Configuration
Manager (Local), you could find list times like SQL Server (<InstanceName>),
the <InstanceName> is exactly what we need to find, instance name. If you
install multiple instances on the server, you will see more than one SQL
Server (<InstanceName>) list times there.
After you find out the instance name, you can determine whether it is a default
instance or named instance. If the instance name is MSSQLSERVER, it is a default
instance. Otherwise, it should be a named instance such SQLEXPRESS, SQL2008
and so on. You can install multiple instances on a server but only one default
instance.
After you get the instance name and know instance type (default or named
instance), you will know the value of server or data source:
For default instance, use <ComputerName> as the server name; and for named
instance, use <ComputerName><InstanceName> as the server or data source.
Note: If the SQL Server instance is installed on the local server, you can also use
localhost, (local), . (dot), 127.0.0.1 (the IP address of localhost), and local IP
address and <ComputerName>. If the SQL Server instance is installed on the
different trusted domain, you may need to use full computer name such as
ComputerName.domain.corp.company.com instead of <ComputerName>. If the
SQL Server installed is public network environment, you may need to use IP
address instead of <ComputerName>. If you just know the IP address/computer
name and the TCP port for a SQL Server named instance, you can use
"tcp:<server ip address/computer name>,<TCP port>" as the value of server or
data source.
Once we get the server value, we can make connections to the SQL Server
instance with the correct connection string as follows:
Server=WinSrv1SQL2008;Database=myDataBase;UID=myUsername;PWD=myPa
ssword;

30
orData Source=WinSrv1SQL2008;Initial Catalog=myDataBase;User
Id=myUsername;Password=myPassword;
How do I configure Windows Firewall to allow remote
connections using TCP/IP protocol for SQL Server?
Answer
On the server on which SQL Server runs, we need to find out which ports that
SQL Server is listening and add which to Windows Firewall Inbound Exceptions.
Firstly, we need to add TCP port on which SQL Server service is listening to the
Windows Firewall Inbound Exceptions so that the client can make connections to
SQL Server over Windows Firewall.
Secondly, if we do not specify TCP port in the connection string and SQL Server is
not listening on the TCP 1433 port, we need to add UDP 1434 port on which SQL
Server Browser Services is listening to the Windows Firewall Inbound Exceptions.
It is because:
a) If TCP port is specified in the connection string, the connection provider such
as SQL Native Client will use this port to connect to SQL Server, so that the
connection provider does not need SQL Server Browser Services to find the
corresponding on which SQL Server is listening;
b) If TCP port is not specified in the connection string, the connection provider
will send a UDP package to 1434 port to the server. So, if UDP 1434 port is
not open in the Windows Firewall therefore the connection provider will not
get the corresponding TCP port on which SQL Server is listening. As a result,
the connection provider will use TCP 1433 port to connect to SQL Server,
which may be failed if the SQL Server does not listen on TCP 1433 port. So as
to make connection to SQL Server in this case, we need to add UDP 1434
port to Windows Firewall Inbound Exceptions.
To find out the TCP port on which SQL Server is listening, please follow the steps
below:
1. Open SQL Server Configuration Manager from Start -> All Programs ->
Microsoft SQL Server 2005/2008/2008 R2 -> Configuration Tools;
2. Click Protocols for <SQLInstanceName> under SQL Server Network
Configuration node in the left panel of SQL Server Configuration Manager
window; Double-click TCP/IP in the right panel, switch to IP Address tab and
you could find out all ports that SQL Server is listening for each IP address or
a specify port for all IP addresses.
Please note that if SQL Server is listening on dynamic ports, its ports may be
changed after restarting each time. As a result, you need to find its current

31
listening TCP port(s) and add all of them to Windows Firewall Inbound
Exceptions.

Could SQL Server 2008 Express edition and SQL Server 2008
R2 Express edition be installed side by side with SQL Server
2005 Express?
Answer
Yes, but we need pay attention to the following points for installing SQL Server
2008 Express and SQL Server 2008 R2 Express side by side with SQL Server 2005
Express:
1. If there is no SQL Server 2005 Express Management Tools installed on the
computer, then the three editions of SQL Server 2008 Express and SQL
Server 2008 R2 Express(SQL Server Express, SQL Server Express with Tools
and SQL Server Express with Advanced Services) could be full installed side
by side with SQL Server 2005 Express.
2. If the SQL Server 2005 Express Management Tools or the alone SQL Server
Management Studio Express are installed, then the Management Tools of
SQL Server 2008 Express and SQL Server 2008 R2 could not be installed since
the tools are installed into a shared directory, we will get the following error
message:
Rule "SQL Server 2005 Express tools failed".
The SQL Server 2005 Express Tools are installed. To continue, remove the SQL
Server 2005 Express Tools.
To solve this issue, we need to uninstall Management Tools of SQL Server 2005
Express from Add/Remove programs.
Installing SQL Server 2008 Express and SQL Server 2008 R2 Express is same with
the other editions, please refer the below links:

Answer
The behavior to apply a service pack for an instance of SQL Server Express Edition
has been changed since SQL Server 2008 than prior SQL Server 2005.
In SQL Server 2005, to install a service pack for an instance of SQL Server 2005
Express Edition, we cannot use SQL Server 2005 Service Pack which is used to
upgrade non-Express Editions but need to use SQL Server 2005 Express Edition
Service Pack. Also, SQL Server 2005 Express Edition can also be used for new
installations. Here are details:
a) To install a service pack for an instance of SQL Server 2005 Express Edition,
please use SQL Server 2005 Express Edition Service Pack.
b) To install a service pack for an instance of SQL Server 2005 Express Edition
with Advanced Services, please use SQL Server 2005 Express Edition with
Advanced Services Service Pack.
However, the behavior was changed since SQL Server 2008. SQL Server 2008
Express Edition Service Pack is only used for new installation (with service pack
patched); and to upgrade an instance of SQL Server 2008 Express Edition, please
use SQL Server 2008 Service Pack instead which can upgrade all editions of SQL

How do I resolve ‘SQL Server Setup cannot valid the service
accounts’ error message during the setup?
Answer
The error message typically happens when you use domain accounts as service
account. If the Activity Directory Service (ADS) is not available currently, so the
setup cannot valid the domain accounts you specify.
As a work around, you can temporarily choose built-in system accounts from
dropdown list during the installation which should work to complete the setup.
However, a built-in system account may have addition privileges than SQL Server
service actually requires. Therefore, we recommend reconfiguring each service
of SQL Server to use an individual domain account or local Windows account.

Why do I get ‘Rule “Existing clustered or
clustered-prepared instance” failed’ error while adding
new features to an existing instance of SQL Server Failover
Cluster?
Symptom
After SQL Server 2008 or 2008 R2 cluster setup, you may want to add new
features that were not installed during the initial installation. Therefore, you try
to add addition features to this cluster. For instance, if you perform this
operation using GUI, you may use the following steps:
1. Start SQL Server setup, and ‘select New installation or add features to an
existing installation’ wizard.
2. Choose the cluster instance which you want to add features to in the
Installation Type page.
3. Select features you want to add and following the wizard.
However, in the ‘Installation Configuration Rules’ page, you get the following
error:
Rule “Existing clustered or cluster-prepared instance” failed.
The instance selected for installation is already installed and clustered on
computer xxx. To continue, select a different instance to cluster.

36
Answer
The cause to this issue is that SQL Server 2008 or 2008 R2 does not support
adding new features to an existing failover cluster instance. However, the
installation is not be blocked until you get the ‘Installation Configuration Rules’
error.
To work around this issue, you could:
a) If you want to install cluster-aware feature such as SSAS or SSRS with failover
cluster, you need to select to install during the initial installation of SQL
Server failover cluster, or install these features as a new installation/instance
after initial installation of SQL Server failover cluster.
b) If you want to install non-cluster features/shared components such as SSMS,
SSIS and etc., you can perform a new installation and select these features
during the installation which will not install a new instance of SQL Server but
only install all those shared components.

How do I exclude data members or create
non-aggregatable values in parent-child dimensions?
Answer
In Analysis Services 2005 and later versions, data members cannot be excluded
from parent-child hierarchies. For example: the one below is the default
parent-child dimension in cube browser:
Amy E.
Alberts
Jae B. Pak Total $8,503,338.65
Rachel B. Valdez Total $1,790,640.23
Ranjit R.
VarkeyChudukatil
Total $4,509,888.93
Total $15,535,946.26
The value of Amy is 15,535,946.26, which includes the data member of Amy
(732,078.44) and the subtotals of children (14,803,867.81). But for some reason,
if you want to exclude the data member of Amy, then you should use an MDX
Script assignment to overwrite the value of Amy:
SCOPE([Measures].[Reseller Sales Amount]);
THIS=IIF(
IsLeaf([Employee].[Employees].CurrentMember)
,[Measures].[Reseller Sales Amount]
,Sum
([Employee].[Employees].CurrentMember.Children
,[Measures].[Reseller Sales Amount])
) ;
ENDSCOPE;
Then you will get the result like this:
Amy E.Alberts Jae B. Pak Total $8,503,338.65
Ranjit R. Varkey
Chudukatil
Total $4,509,888.93
Total $14,803,867.81
If you want to display data members for a parent-child hierarchy, then you can
use an MDX Script assignment to overwrite the value of Amy:
SCOPE([Measures].[Reseller Sales Amount]);

Analysis Services
40
THIS=([Employee].[Employees].CURRENTMEMBER.DATAMEMBER,
[Measures].[Reseller Sales Amount]);
ENDSCOPE;
Then you will get the result like this:
Amy E. Alberts Jae B. Pak Total $8,503,338.65
Ranjit
R.VarkeyChudukatil
Total $4,509,888.93
Total $732,078.44

values. But using Script is better for performance.

How do I specify a calculated member as the default
member of an attribute?
Answer
If you specify a calculated member as the default member in the properties
window, then you will receive an error message. This is because you create the
calculated member in MDX Script but process the default member specified in UI
before the MDX Script is executed. So you will see the error because no
calculated member was found.
You can use ALTER CUBE statement at the end of MDX Script, or just execute the
Script in SSMS:

Default_Member = [Destination Currency].[Destination Currency].[US Dollar];

average sales amount of customers for all dimensions, then you can try this:
1. Create a measure [Customer Count] withaggregation DistinctCount for the
customers.
2. Create a measure [Sales Amount] withaggregation Sum for the sales amount.
3. Create a calculated measure with expression: [Sales Amount]/ [Customer
Count], and then set the additional properties.

How do I implement dynamic security for the users?
Answer
There is a dimension Reseller in our cube, and we can create roles to grant each
user (Reseller) access to the cube to let them see their own sales data. However,
if there is a large number of users, then we need to create lots of roles. Even if
you can create so many roles, it’s still hard for maintenance. But, we can
implement dynamic dimension security for each reseller. You can try the steps
below:
1. Create a Users table containing the users in the underlying database. Create
a dimension named User from this table.
2. Create a Factless table to maintain the relationship between the users and
the Resellers:
users | Resellers
user1 ResellerA
user1 ResellerB
user2 ResellerB
After that, create a measure group base on this table.
3. The relationship in DSV is similar like this:
User <- Factless -> Reseller <- fact table
So, create regular relationship between the two dimensions and the Factless
measure group.
4. Create a role for the users, in Dimension Data tab, select the attribute
Reseller in dimension Reseller, switch to Advanced tab, the allowed member
set should be:
NonEmpty( Reseller.Reseller.Members,
( StrToMember("[Users].[User].["+UserName()+"]"),
[Measures].[Bridge Reseller Users Count] ))
Test the role in your cube browser, if it works then deny access to the
dimension user and the factless measure group.

What is the common usage of Unknown member?
Answer
Unknown member is useful for referential integrity issues and the NULL values
issue. There are two scenarios:
Referential Integrity
You may encounter this error message:
“No record (key) found in dimension“
If some records in your fact table are not found to have matched keys in your
dimension table. For example:
Fact table:
ProductKey Value
1 1
2 2
3 3
100 100
Dimension table:
ProductKey Family
1 Food
2 Food
3 Beverages
To overcome this error message, you can configure the error message setting
and the unknown member setting through the link below
Then you will see the results below in Browser:
Key Value
1 1
2 2
3 3
Unk 100
NULL Values
Same fact table, but for the dimension table, we add one row:
ProductKey Family

Analysis Services
45
1 Food
2 Food
3 Beverages
4 NULL
Create a natural hierarchy Family -> ProductKey, set the attribute relationship
ProductKey <- Family. After that, modify the keycolumn setting of the attribute
Family, convert NULL to unknown member (Unk). Remember to reprocess the
dimension then you will see the results below in Browser:
Food Value
1 1
2 2
Beverages
3 3
Unk

How do I use wildcards in MDX?
Answer
There is no build-in function for this. Generally, we can achieve that through the
approaches below:
1. Using VBA function instr() in Filter(), for example:
SELECT
{} ON 0
,Filter
(
{[Employee].[Employees].MEMBERS}
,
VBA!Instr([Employee].[Employees].CurrentMember.Name,"RA") > 0
) ON 1
For more information about the Instr(), you can refer to:

2. Using Stored Procedures. You can create your own Stored Procedures to
achieve this, you can also download Analysis Services Stored Procedures
project from:
http://www.codeplex.com/wikipage?ProjectName=ASStoredProcedures

How do I query multi-dimensional data in a relational
database with T-SQL?
Answer
You can use OpenQuery and OpenRowSet to execute pass-through queries
against a cube. You can try the steps blow against sample database:
1. In SSMS (SQL Server Management Studiu), connect to the database engine,
expand the folder ‘providers’ below the folder ‘linked server’, double click
the provider ‘MSOLAP’, and then ensure option ‘Allow InProcess’ has been
selected.
2. create a linked server:
@server='TestForOpenQuery', -- the given name to the linked server
@srvproduct='',
@provider='MSOLAP',
@datasrc='localhost',--the instanse name of SSAS(machine/instanse)
@catalog='Adventure Works DW 2008'
3. Execute the query:
SELECT "[Product].[Category].[Category].[MEMBER_CAPTION]" AS Category,
ROUND(CONVERT(float,"[Measures].[Internet Sales Amount]"),2) AS Amount
FROM OpenQuery(TestForOpenQuery, 'select {[Measures].[Internet Sales
Amount]} on 0, [Product].[Category].members on 1 from [Adventure
Works]')
Then you will get this:
Category Amount
NULL 29358677.22
Accessories 700759.96
Bikes 28318144.65
Clothing 339772.61

How do I resolve the error "File system error: A FileStore
error from WriteFile occurred. Physical file: ...." when I
process a dimension by using the Process Update option?
Answer
When you process a dimension by using the Process Update processing option or
the Process Default processing option, the string file store (.asstore) is appended
instead of being overwritten. This behavior reduces the process time even if no
change is made on the string attribute. If the dimension is frequently processed
that way, the string file store will become very large. When the string file store
reaches 4 GB, you can no longer process the dimension by using the Process
Update processing option or the Process Default processing option. You will
receive an error message:
“File system error: A FileStore error from WriteFile occurred. Physical file: ....”
If you are doing ProcessUpdate on a regular basis, I would suggest doing
processFull now and then. When you process a dimension by using the Process
Full processing option, all the data of the dimension will be dropped and
reconstructed. The string file store will be smaller.

How do I connect to a SSAS cube through Internet?
Answer
Sometimes your company has security policy that restricts you to access the SQL
Server Analysis Services through TCP/IP protocol since most TCP ports are not
allowed by firewall. In this case, you can set up HTTP access to your Analysis
Services instance.
The following articles are helpful for you to configure HTTP Access to your SSAS
on different OS:
Configuring HTTP Access to Analysis Services on Microsoft Windows XP
Configuring HTTP Access to Analysis Services on Microsoft Windows Server
2003
There is a third party blog which extends the description on configuring this on
Windows Vista. We post the link here just for your reference:

What will happen if I create two roles for a user?
Answer
Permissions across multiple roles are additive. If a user belongs to a role which
has access to all dimensions, then he/she will always have this permission even if
we have created another role to restrict this user. So, you may need to check the
roles you belong to. You can try the statement below:
SELECT * FROM $SYSTEM.DBSCHEMA_CATALOGS
The Roles column will have a comma-separated list of the roles that users belong
to for that database. However, it only returns the current users’ role. So, if you
are an administrator, it will return all roles.
You can choose which roles you would like to use to connect to a server by
specifying Roles parameter in your connection string. For example:
Data Source=myASserver;Initial Catalog="Adventure Works
DW";Roles=Operation Manager, Sales Manager;

How do I connect to SSAS instance without SQL Browser
services started?
Answer
By default SSAS uses the TCP port 2383 (the configured port is 0). SQL Server
Browser Services uses the TCP port 2382 for redirecting client requests to the
correct Analysis Services instance. However if SQL Server Browser Services is not
started or not allowed to start by company security policy when a client tries to
establish a connection, it cannot locate the SSAS instance. To resolve this issue,
you need to explicitly specify the TCP port in your connection string in your
client.
For example:
AdomdConnection cn = new AdomdConnection("Data
Source=myASserver:2383;Initial Catalog=ASTest;Integrated
Security=SSPI;");
try
{
cn.Open();
MessageBox.Show("Succeed!");
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
finally
{
cn.Close();
}

How do I keep on accessing my cube in MOLAP storage
mode when it is processed?
Answer
Generally there are two solutions:
1. Use proactive caching
2. Incorporate a staging server
If there are only data changes in the data source, you can use proactive caching
for transparent processing. You do not have to manually process the cube and it
can provide minimum latency.
The second method of using a staging server is useful when there are structure
changes in your cube definition. In this case, a whole cube process may be
required. By incorporating a staging server, you can perform cube processing
jobs on the staging server. After that, use the Synchronize Database Wizard to
synchronize the Analysis Services database between your staging server and
production server.

How do I have the members of a dimension displayed in
my custom order?
Answer
This can be implemented by introducing an additional attribute column for
display order and setting OrderByAttribute to the new attribute column. Let us
say that your dimension attribute name is Type.
Then you can follow these steps to define the display order of the Type
members:
1. Create a Named Calculation for the dimension
In your data source view (DSV), you can add a named calculation
"DisplayOrder" to your dimension. The Expression is:
CASE
WHEN Type='A' THEN 3
WHEN Type='B' THEN 1
WHEN Type='C' THEN 2
WHEN Type='D' THEN 4
ELSE 5
END
2. Add the DisplayOrder to the dimension attribute
Open the dimension, under Dimension Structure, right-click the DisplayOrder
in the Data Source View panel, click "New Attribute from Column".
3. Set the attribute properties
Select "Display Order", set the attribute "Attribute Hierarchy Enabled" to
False, set"AttributeHierarchyOptimizedState" to "NotOptimized" , set
AttributeHierarchyOrdered to False, set "AttributeHierarchyVisible" to False.
4. Define Attribute Relationship.
Select Attribute Relationship tab, right click Type, click New Attribute
Relationship, choose Type as the Source Attribute and Display Order as the
Related Attribute.
5. Switch to the Dimension Structure tab, select the Type attribute, set its
property "Order By" to "AttributeName", and set "OrderByAttribute" to
"Display Order".
6. Save the changes and process your dimension.

How do I run MDX query in Excel 2007/2010?
Answer
Currently in Excel 2007, it is a limitation that you cannot directly execute MDX via
UI input. The following three methods are common workarounds:
1. Modify the connection file (.odc).
When you create a SSAS connection, there will be a connection file (.odc)
generated in the folder C:Users<username>My DocumentsMy Data Sources.
Open the connection file with note pad and you will find a piece of XML code in it
like the following:
< xml id=docprops><o:DocumentProperties
xmlns:o="urn:schemas-microsoft-com:office:office"
xmlns="http://www.w3.org/TR/REC-html40">
<o:Name>. PueStores</o:Name>
</o:DocumentProperties>
< /xml><xml id="msodc">
<odc:OfficeDataConnection
xmlns:odc="urn:schemas-microsoft-com:office:odc"
<odc:Connection odc:Type="OLEDB">
<odc:ConnectionString>Provider=MSOLAP.4;Integrated
Security=SSPI;Persist Security Info=True;Data Source=.;Initial
Catalog=PueStores</odc:ConnectionString>
<odc:CommandType>Cube</odc:CommandType>
<odc:CommandText>PueStores</odc:CommandText>
</odc:Connection>
</odc:OfficeDataConnection>
< /xml>
Now you just need to change two places. Change the <odc:CommandType> value
to "MDX" and <odc:CommandText> value to your MDX statement. For example:
< xml id=docprops><o:DocumentProperties

Analysis Services
56
xmlns:o="urn:schemas-microsoft-com:office:office"
<o:Name>. PueStores</o:Name>
</o:DocumentProperties>
< /xml><xml id="msodc">
<odc:OfficeDataConnection
xmlns:odc="urn:schemas-microsoft-com:office:odc"
<odc:Connection odc:Type="OLEDB">
<odc:ConnectionString>Provider=MSOLAP.4;Integrated
Security=SSPI;Persist Security Info=True;Data Source=.;Initial
Catalog=PueStores</odc:ConnectionString>
<odc:CommandType>MDX</odc:CommandType>
<odc:CommandText>
SELECT NON
EMPTY{([Store].[Store].AllMembers,[Measures].[Sales Amount])} on 0,
NON EMPTY [Date].[YTD].AllMembers ON 1
FROM [PueStores]
< /odc:CommandText>
</odc:Connection>
</odc:OfficeDataConnection>
< /xml>
Save the file, and then in Excel, click Data->Existing Connections, select the
connection under "Connection files on this computer" and click Open. This can
be a workaround but it is not very convenient if you need to change the MDX
statement.
2. Execute MDX via a SQL Server stored procedure
To do this, you need to first create a stored procedure in a database. For easy
use, I create it in a master database:
create procedure myMDX(@mdx varchar(max))
as
DECLARE @strSQL nvarchar(max)
SET @strSQL=N'SELECTa.* FROM OpenRowset(''MSOLAP.4'',''DATASOURCE=
localhost ; Initial Catalog=PueStores;'','''
+ @mdx +''') as a'
EXEC sp_executeSQL @strSQL
Then in Excel 2007, select Data->From Other Sources->From Microsoft Query,
create a new data source for your SQL Server instance with "SQL Server Native
Client" driver, choose the default database to master. After you create the data

Analysis Services
57
source, click OK, in the pop-up designer window, click Close to close the inner
query editor window, and then click File->Execute SQL…, choose the data source
and input the following SQL:
exec myMDX 'SELECT NON
EMPTY{([Store].[Store].AllMembers,[Measures].[Sales Amount])} on 0,
NON EMPTY [Date].[YTD].AllMembers ON 1
FROM [PueStores]'
Then close the window, you can choose Table or PivotTable to display the output.
The advantage of this method is that you can directly change the MDX statement
in the connection properties and the data will be refreshed. The disadvantage is
that you are introducing an intermediate SQL Server instance for query.
3. Install an add-in for Excel like OLAP PivotTable Extensions.
There are some third-party add-ins for Excel like OLAP PivotTable Extensions,
however since this is a third-party software, before you make the decision to use
it, please first test it and make sure that it applies to your corporate policy.

How do I process a cube via T-SQL?
Answer
There are some methods like starting a SQL job to execute Analysis Services
command or using xp_cmdshell to execute ascmd to process a cube. However
these methods require additional RPC calls and do not look graceful. A better
way is to create a CLR stored procedure to process the cube.
1. Alter your database to set it to Trustworthy
ALTER DATABASE Test SET TRUSTWORTHY ON
2. Run "CREATE ASSEMBLY" to load the ADOMD.NET assembly
CREATE ASSEMBLY [AdomdClient]
AUTHORIZATION [dbo]
FROM 'C:Program
FilesMicrosoft.NETADOMD.NET100Microsoft.AnalysisServices.Ad
omdClient.dll'
WITH PERMISSION_SET = UNSAFE;
3. Create a SQL Server Database project, add the reference AdomdClient under
the SQL Server tab.
4. Create a CLR stored procedure as following:
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using Microsoft.AnalysisServices.AdomdClient;
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]

AdomdConnection conn = new AdomdConnection(String.Format("Data
Source={0}", strServer));
conn.Open();
//Create a command, and assign it an XMLA command to process
the cube.
AdomdCommand cmd = conn.CreateCommand();
cmd.CommandText = String.Format("<Process
xmlns="http://schemas.microsoft.com/analysisservices/2003/engine
">rn" +
@"<Object>
<DatabaseID>{0}</DatabaseID>
<CubeID>{1}</CubeID>
</Object>
<Type>ProcessFull</Type>
< /Process>", strDbName, strCubeName);
//Execute the command
int result = cmd.ExecuteNonQuery();
//Close the connection
conn.Close();
}
};
5. Set the Project property "Permission Level" to Unsafe.
6. Build the project and deploy it to your SQL Server database.
7. Enable clr on your SQL Server by using sp_configuration
sp_configure 'clr enabled',1
go
reconfigure with override
go
8. Execute the stored procedure.

How do I troubleshoot the slow MDX query performance?
Answer
For MDX query performance, it is usually caused by the following factors:
1. Bottlenecks from SSAS Formula engines.
2. Bottlenecks from SSAS Storage engines.
3. Bottlenecks from system resources.
You can use SQL Server Profiler and System Performance Monitor to track the
cause of the issue. For formula engines, you need to check the following events:
Query SubCube
Query Begin
Query End
You can determine how much time the storage engine consumes by checking the
Query SubCube event's Duration value. Compare it with the Duration value in
Query End event. If it is larger than 30%*(Duration in Query End event), your
SSAS storage engine may have performance bottlenecks. You can add Query
SubCube Verbos event for more detailed information on the TextData column.
When this issue happens, you can consider refreshing your cache or using
partitions to improve performance.
If the subtraction between the total time of query and the time spent on Query
SubCube is the query cost spent on formula engine. If it is larger than
30%*(Duration in Query End event), your SSAS formula engine may have
performance bottlenecks. You need to narrow down the cost of the query by
adding more events under Query Processing.
For bottlenecks from system resources, you need to use System Performance
Monitor to monitor your server and Analysis services instance to check if there is
any memory, I/O, CPU, and network bottlenecks.

How do I achieve nested aggregation?
Answer
To avoid using Expression with nested aggregations “Sum(Max(Data))”, you can
change the dataset. For example: add a new column in your dataset to calculate
the Max value for the group and then use the Sum(Max(…)) in your report.
Or you can try the workaround below. Imagine that group1 contains group2 and
group2 contains details, and you want to use sum(max(data)):
1. Add a “fake” in dataset like this
UNION
SELECT '_fake' AS Group1, '_fake' AS Group2, '_fake' AS
Detail, … …
2. Sort the data by descending, so the fake data will show at the last group
because of the character ‘_’.
3. Copy the following code to the custom code area:
Dim Aggregation as Decimal
Function AddValue(ByVal NewValue As Decimal) as Decimal
Aggregation = Aggregation + NewValue
Return Aggregation
End Function
Function GetAggregation () as object
GetAggregation = Aggregation
Aggregation = 0 'Reset the group
Return GetAggregation
End Function
4. Delete the footer of group1, then right-click the handle of group1’s header
and insert a row above. Below is the structure:
Group 1 new Header
Group 1 Header
Group 2 Header
details
Group 2 Footer

lue)
=code.GetAggregation
()
1 = (Fields!group1.Value)
2 =Fields! Group2.Value =code.AddValue(max(
data))
== Details details
(Table footer)
5. Right-click the handle of the new header, click the properties (not edit
group). In Properties window, set the visibility to be
“=iif(Previous(Fields!group1.Value) is nothing, true,false)”.
6. Right click the handle of each one of the other rows, click the properties (not
edit group). In Properties window, set the visibility to be
“=iif(Fields!group1.Value = "_fake", true,false)”.

How do I achieve column break in a matrix?
Answer
Here are some workarounds, available forboth Reporting Services 2005 and2008:
Workaround 1
Spread the columns from one matrix into several matrixes. You can first copy one
matrix and then paste it into several ones you want. Then set the filter for each
column group to make sure that the total columns’ length in one matrix just fit a
page’s width.
Workaround 2
The other method is to use a custom code.
1. Please copy the following code to the custom code area:
Dim FlagTable As System.Collections.Hashtable
Dim Flag AS Integer
Function MyFunc(ByVal NewValue As Object) As Integer
If (FlagTable Is Nothing) Then
FlagTable = New System.Collections.Hashtable
End If
If (NewValue Is Nothing) Then
NewValue = "-"
End If
If (Not FlagTable .Contains(NewValue )) Then
Flag =Flag + 1
FlagTable.Add(NewValue, nothing)
End If
MyFunc = Flag
End Function
2. Create a list in your report.
Imagine that the column group of a matrix is grouped bythe field
‘Column_Group’, then set the detail group of list withthe expression like this:
=Ceiling(Code.MyFunc(Fields!Column_Group.Value)/5)
Note: This means the Max number of column in matrix will be five after you
follow step C.
3. Sort the dataset by column group field, and then drag the matrix into the list.
Click Preview.
Workaround 3

Reporting Services

Similar to the second method, you need to modify the dataset.
1. Create an ID column for the column group in your dataset.
For example,there isa datasetwith the following query:
SELECT * FROM Table
The column group is grouped on the field “Group1”.Then, modify the query
like this:
SELECT *, Dense_Rank()OVER(order by Group1) AS ID FROM Table
2. Create a list in your report, set the detail group of the list with the Expression
like this:
=Ceiling(Fields!ID.Value/5)
Note: This meansthat the Max number of column in matrix will be five after
you followthe step C.
3. Sort the dataset bythe column group and then drag the matrix into the list.

How do I use Parent-Child Hierarchies and formatted value
in report with Analysis Services?
Answer
To resolve this issue, you can use the Extended Field Properties which is
supported in SSRS.
To retrieve the extended properties, for example Formatted Value, you need to
add the properties to the MDX query:
VALUE,BACK_COLOR,FORE_COLOR ,FORMATTED_VALUE
,FORMAT_STRING,FONT_NAME,FONT_SIZE,FONT_FLAGS
Afterwards, use the extended property in your cube:
=Fields!Employees.FormattedValue
For more information, reference:
Imagine that Employees is the Parent-Child Hierarchy, so the group expression in
report could be:
=Fields!Employees.UniqueName
Father group expression could be:
=Fields!Employees.ParentUniqueName
Value expression could be:
=Fields!Measure.FormattedValue
Afterwards, set the visibility property, padding property for the report as above
documents described.
Next, you may want to filter the data in your report. For example, just display
memberA and the descendant and ancestor of memberA. Simply creating the
filter in report may not work, because you may destroy the parent-child
relationship. It can be achieved in query designer. Drag the hierarchy to the filter
pane, select the option ‘Parameters’. Or try the query below to display
descendant and itself:
SELECT
NON EMPTY
{[Measures].[Reseller Sales Amount]} ON COLUMNS
,NON EMPTY
{Descendants(StrToSet(@EmployeeEmployees,CONSTRAINED))}
DIMENSION PROPERTIES MEMBER_CAPTION,MEMBER_UNIQUE_NAME

Reporting Services
71
,PARENT_UNIQUE_NAME ,LEVEL_NUMBER
ON ROWS
FROM [Adventure Works]
CELL PROPERTIES
VALUE,BACK_COLOR,FORE_COLOR ,FORMATTED_VALUE
,FORMAT_STRING,FONT_NAME,FONT_SIZE,FONT_FLAGS;
Note: For relational databases, if you want to filter the members, you need to
create a dataset with Common Table Expressions (CTE). For example:
WITH CTE AS
(
SELECT * FROM TABLE WHERE ID= @ID
UNINON ALL
SELECT T1.* FROM TABLE T1, CET T2
WHERE T1.ParentID = T2.id
)
SELECT * FROM CTE

How do I set interactive sort across multiple groups in SSRS
2005?
Answer
One possible workaround is using drill-through action to create a fake
‘interactive sort’:
1. Copy and paste the table1 to create a table2.
2. Select the table1, click and edit each group, switch to the Sorting tab, select
a proper column with Ascending/Descending direction for sorting. Select the
table2, click and edit each group, sort the records with a different direction.
3. Click the cell which contains the interactive_sort button in table1, add a new
column to the left. Merge the cells in these two columns row by row except
the table header. After that remove the interactive sort from the table1 by
unchecking the option “Add an interactive sort action to this textbox”.
Repeat this step for table2.
4. Create a hidden parameter for the report named Sorting. Set the default
value for this parameter to be “Ascending”.
5. Right click the new added cell in the header of the table1, click properties,
and switch to Navigation tab. Select the “Jump to report”, choose the
current report, set the parameter value of @Sorting to be: “Descending”.
After that, select table1, click properties, switch to Visibility tab, set the
visibility with expression:
‘=iif(Parameters!Sorting.Value="Ascending",false,true)”.
6. Right click the new cell in table2, click properties, and switch to Navigation
tab. Select the “Jump to report”, choose the current report, set the
parameter value of @Sorting to be “Ascending”. After that, select table2,
click properties, switch to Visibility tab, set the visibility with expression:
‘=iif(Parameters!Sorting.Value=" Descending",false,true)’.
7. You can merge the cells in these two columns except the cells in header. You
can also create two pictures for those two cells, one for Descending and one
for Ascending. After that, set drill through action on these two pictures.
For matrix, there are some differences.
a) Since the sorting button must be a static cell and you cannot split the matrix
header in SSRS 2005, you can only set interactive sort on matrix header (left
top corner) in SSRS 2005. But in SSRS 2008, you have multiple choices since it
has multiple matrix headers.
b) You cannot sort the detail data in matrix since there is only one detail cell in
one column group and one row group for a matrix. For example, look at the
below matrix

Reporting Services
73
Matrix Header A B
C 1 2
D 3 4
There is only one value 1 for (A, C), so sorting that value is no meaningful. And
even if you can sort the values (1 and 3) on the column A, you will find that the
sort will also impact on the column B, that means 2 and 4 will be also sorted. So
you can only sort on groups or subtotals – (sort X-axis or Y-axis).
For sorting row/column group, right click the matrix header, click properties, and
then switch to the Interactive Sort tab, and set the sorting group region and
sorting expression. In Reporting Services 2005, if the row/column group is not in
the drop down list of ‘evaluate sort expression’, you can type the row/column
group name in that textbox.
After that, if you want to set the interactive sort for row group and column group
at one time, you can try the above work around (for table) – using drill through
action. Create two matrixes, right click the group, click edit group, sort the
groups in sort tab of, and then create drill through with parameter.

How do I get distinct values of SharePoint column using
SQL Server Reporting Services?
Answer
You can use custom code to get distinct records.
Here are the detailed steps:
1. Create a new dataset same as the main dataset, and then create a hidden
parameter that gets all the records in one field of the new dataset.
2. Create a function that used to remove the duplicate records.
Here is the code:
Public Shared Function RemoveDups(ByVal items As String) As String
Dim noDups As New System.Collections.ArrayList()
Dim SpStr
SpStr = Split(items ,",")
For i As Integer=0 To Ubound(Spstr)
If Not noDups.Contains(SpStr(i).Trim()) Then
noDups.Add(SpStr(i).Trim())
End If
Next
Dim uniqueItems As String() = New String(noDups.Count-1){}
noDups.CopyTo(uniqueItems)
Return String.Join(",", uniqueItems)
End Function
3. Create another parameter that will be used for filtering the main data.
Please set the available value to be
=Split(Code.RemoveDups(JOIN(Parameters!ISSUE_STATUS_TEMP.Value, ",")),
",")
And the default value to be the value you wanted, such as the first value:
=Split(Code.RemoveDups(JOIN(Parameters!ISSUE_STATUS_TEMP.Value, ",")),
",").(0)
4. Select the main dataset and open the property window of this dataset.
5. In the “Filters” tab, set the filter to be:
Expression: <The field to be filter>
Operator: =

Reporting Services
75
Value: =Parameters!Region.Value
The parameter “Region” should be the parameter we created in the step3. Now,
we could get the distinct values of SharePoint columns.
How do I resolve the printer problem “Unable to load
client print control”?
Answer
The issue could be caused if the RSClientPrint control has been updated after the
Report Server got updated.
The Reporting Services uses the CLSID of the RSClientPrint control and a function
in the control to check if the RSClientPrint control has been installed in the client.
If the CLSID is not the one the server required, the server will throw the
exception “Unable to load client print control”.
For example, the old CLSID is “{FA91DF8D-53AB-455D-AB20-F2F023E498D3}”.
After applying SQL Server 2005 Service Pack2 or later, the CLSID should be
“{41861299-EAB2-4DCC-986C-802AE12AC499}”. If the client has the control with
the ID “{FA91DF8D-53AB-455D-AB20-F2F023E498D3}”, and the server has been
updated, then we will encounter the error.
I would suggest using the following steps to solve the issue:
1. Install Windows Resource Kits.
2. Use the “oleview.exe” to check if the RSClientPrint 2005 Class (Object Class
-- > Grouped by Component Category -- > Controls) has been installed.
3. If the control has been installed in the client, please remember its CLSID that
is displayed in the right window of OLEVIEW.
4. Open Internet Explorer
5. Click “Tools” -- > “Manage Add-ons” to manage add-ons.
6. Select “All add-ons”, and then select “RSClientPrint 2005 Class”
7. Click “Delete” to delete the control. Or “Disable” to disable the control.
8. Re-run a report, and click Print. Now the RSClientPrint control will work fine.
9. Re-open the OLEVIEW to check the newer CLSID.
If the new CLSID is different from the old one, the issue is the one we have
described above.

How do I allow Enter key to act like the “view report”
button?
Answer
While clicking the “View Report” button, the report sever uses JavaScript to
verify the parameters and submit the action. There, the report manager uses the
“Report.aspx” to display the parameter panel, and the report server uses the
“ReportViewer.aspx” to display the parameter panel. We can implement a
custom function using JavaScript that allows us to view the report by Enter key.
Please follow these steps to allow Enter key to act like “View Report” button:
1. Open the “Report.aspx” using notepad.
By default, the file located at:
C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting Services
ReportManagerPages
2. At the end of the file, embed the following code.
<script language = "Javascript">
function GetViewReportBtn() {
dueTime += 50;
if (dueTime > 30000) {
clearTimeout(timer);
return;
}
var obj = document.getElementsByTagName("INPUT");
for (var i = 0; i < obj.length; i++) {
if (obj[i].type == "submit" && obj[i].value == "View Report")
{
clearTimeout(timer);
return obj[i];
}
}
timer = setTimeout(GetViewReportBtn, 50);

}
var dueTime = 0
var timer;

var btnViewReport;
btnViewReport = GetViewReportBtn();
if (btnViewReport)
btnViewReport.click();
}
}
</script>
3. Save the file.
4. Open the “ReportViewer.aspx” using notepad.
By default, the file is located at:

How do I avoid prompting Login dialog while deploying
report from Microsoft Business Intelligence Development
Studio?
Answer
If you installed Business Intelligence Development Studio on Windows Vista or
Windows Server 2008, you will encounter compatibility issues with the Visual
Studio environment when you use the design tools. If you want to open an
existing project or solution, or publish items from Report Designer or Model
Designer to a report server, you must open Business Intelligence Development
Studio with elevated permissions:
1. From the Start menu, click All Programs, click SQL Server 2008, right-click
Business Intelligence Development Studio, and then click Run as
administrator.
2. Click Continue.
3. Click Run Program.
You should now be able to deploy reports and other items to a report server. If
you do not have sufficient permissions, you will encounter issues such as the
following:
1. Access Denied errors when you try to open an existing project.
2. Login failure errors when you configure a data source connection to a shared
data source.
3. When using the Report Server Wizard to create a report, you will get a login
failure error when the Wizard attempts to connect to the external data
source that provides data to the report.
SQL Server Management Studio users must use Run as administrator permissions
to create logins for users who administer databases on the server. For more

information about elevated permission requirements for Management Studio,
see How to: Connect to SQL Server from Windows Vista.
More information, please see:
How to: Configure a Report Server for Local Administration on Windows Vista
and Windows Server 2008
Another possible issue should be Kerberos. If we use a domain account to run
the SQL Server Reporting Services, and we have not configured the Kerberos in
the domain environment correctly, we will get the login dialog.
To solve the issue, we can configure the Kerberos or change the services account
to a local services account.
Please follow these steps to change the account to a local services account:
1. Run command “inetmgr” to open Internet Information Server manager.
2. Select the application pool that the Reporting Services is running under.
3. Right-click the application pool, and then click “Properties”
4. Go to “Identity” tab.
5. Check item “Predefined”, and select “Network Service”.
6. Click “OK” to apply.

How do I anonymously access the Report Manager?
Answer
The following steps describe how to anonymously access Report Manager:
1. Add the anonymous user to the System User role.
2. Create an Item-level role with all of the tasks you want this user to be able to
use, and then assign the anonymous user to that role at the root level. ( Step
1 and Step 2 could be accomplished by using Report Manager only if
Anonymous access is disabled and the logged-on user is a member of the
System Administrator role.
3. Check permissions for the anonymous user on folders that Reporting
Services use:
- C:Program FilesMicrosoft SQL ServerMSSQLReporting Services (and
subfolders)
- C:<windows>Microsoft.NETFrameworkv1.1.4322Temporary ASP.NET
Files
-Temp folder for the anonymous user
Note: We don’t suggest using Anonymous access to Report Manager. When
using Anonymous access, every person hitting that page will be under the
Anonymous user context, and no one will have rights to administer Reporting
Services through Report Manager.

How do I deploy a Report Server for Internet Access?
Answer
Some settings in the rswebapplication.config file are used to direct requests from
Report Manager to a report server. Report Manager uses the ReportServerUrl
settings in the configuration file to find the report server. In an intranet
deployment model, the Report Manager connects to a report server using the
network name like this (for example, http://server01/reportserver).
However to access a report server on the Internet, you need to configure the
ReportServerUrl that specifies the fully qualified domain name of the report
server. The external client uses this value to access a report server. In this
scenario, the browser that is hosting Report Manager must send a fully qualified
domain name when making requests on behalf of Report Manager to the report
server. The following example illustrates the syntax for ReportServerURL:
<ReportServerURL>http(s)://<server.domain.com>/reportserver</ReportServerU
RL>
If you use SharePoint 2.0 Web Parts for Reporting Services, you need to
configure this setting in <ReportServerExternalURL> section:
<ReportServerExternalURL>http(s)://<server.domain.com>/reportserver</Repor
tServerExternalURL>
Note: This element is not included in the RSReportServer.config file, to use it, you
need to add it yourself.

How do I dynamically load an external image in a report?
Answer
Generally there are two possible reasons for the issue:
1. If you want to use a directory string, and the images are stored in the file
folder which is not in the root folder of the Website populate SQL Server
Reporting Service, there will be a permissions error. If using IIS6.0 as the web
server, the account “Network Service” (“ASPNET” for IIS5.0) must have the
permission “Read” in the folder.
2. If you want to use an URL, and the images are stored in a website which is
not the same as the populate SQL Server Reporting Service Website.
Therefore an execution account error will occur.
To solve the issue, we could use either of the following two solutions below:
Use the folder of images “images” as a sample.
Solution1: Using Directory string.
1. Store the images in any folder on the SQL Server Reporting Server.
2. Set the account “Network Service”(or “ASPNET”) “Read” permission.
3. Store the Directory string in the “Pointer” field in the table. The Directory
string must be full, and with prefix file://. Do not use quotes. For example:
file://D:/images/ XXX.jpg (“.png”, “.gif”, and so on).
4. Design the report, and set the property “Value” of image control as “=Fields!
Pointer.Value”.
Solution2: Using URL
1. Store the images in the file system in one of the websites on the server.
2. Open Reporting Service Configuration Manager, navigate to “Execution
Account”.

Reporting Services
86
3. Specify an account.
4. Store the URL in the “Pointer” field in table, and the URL must be full. Do not
use quotes. For example: http ://< website >/images/XXX.jpg (“.png”, “.gif”,
and so on).
5. Design the report, and set the property “Value” of image control as “=Fields!

How do I get group total in Group Footer with PageBreak in
SQL Server Reporting Services?
Answer
I want to get a total of certain group within a group footer of the Tablix, which
has another group for breaking the records on certain number of records. For
example,There is a table with a amount of data and its columns include
"CustomerID", "CustomerType" and "Totaloutstanding". Now, run SSRS 2005 to
report this table data. On this report,
1. In the report dataset, these data are ordered by "CustomerID", one
CustomerType has one CustomerID, the CustomerID values like 1,2,3......
2. Insert a Table control to host these data,
3. The data on every page of this report has only less than or equal 1000 rows.
To achieve this, insert a group for the detail rows with group-on expression
=(RowNumber(Nothing)-1)1000. Assuming this group is Group1.
4. The data on every page of this report need to be grouped by
"CustomerType". To achieve this, insert a group under the Group1 for the
detail rows with group-on expression =Fields!CustomerType.value, and tick
these options "Include group header","Include group footer" and "Repeat
group header". Assuming this group is Group2.
5. (?). How to display the subtotal based on CustomerType at the end of each
CustomerType series? Note that one CustomerType might be span multiple
pages by Group1, and one page(Group1 instance) might have multiple
Group2 instance.
There are 2 main steps, one is how to calculate the subtotal based on the
"CustomerType", and the other is how to hide the Group2 footer rows if they are

Reporting Services
88
not at the end of each CustomerType series.
1. The possible alternatives for how to calculate the subtotal based on the
"CustomerType", there are 2 options you can follow:
Use semi hard-code: In the Group2 footer cell, type this expression
=Switch(Fields!Customer.Value="Person",SUM(IIF(Fields!Customer.Value="Perso
n",Fields!Totaloutstanding.Value,0),"StatisticTbl"),Fields!Customer.Value="Comp
any",SUM(IIF(Fields!Customer.Value="Company",Fields!Totaloutstanding.Value,
0),"StatisticTbl"),Fields!Customer.Value="Electronic",SUM(IIF(Fields!Customer.Va
lue="Electronic",Fields!Totaloutstanding.Value,0),"StatisticTbl")) . Note that
"StatisticTbl" is the report dataset name, and "Person","Company" and
"Electronic" are the "CustomerType" examples.
Use the subreport to do this:Create a new report, dataset:
select CustomerType,sum(Totaloutstanding) as subtotal
from StatisticTbl
where CustomerType= @cust
group by customerType
report parameter:name->cust, datatype->string
report body: drag a table control and only one detail cell via deleting other cells,
and put the =Fields!subtotal in this cell. Adjust this report page size to fit on
one cell of the main report Group2 footer. On the main report, in the cell
displaying the subtotal of "CustomerType" of Group2 footer, insert a Subreport
control to reference this newly created report and set this subreport parameter
"cust" point to =Fields!CustomerType.value.
2. After implementing any option of the first step, the subtotal based on the
"CustomerType" will be displayed in each Group2 footer. Now, how to hide
these footer rows not at the end of the "CustomerType" series? Click the
handle of the Group2 footer row to select the entire row, and locate its Hidden
property under Visibility note in the Properties box, then type the following
expression to hide the footers not at the end of each "CustomerType":
=IIF(Runningvalue(Fields!CustomerType.Value,countdistinct,"Group1")=1,IIF(Co
unt(Fields!CustomerType.Value,"Group2")=1000,true,false),false)

8. Click ok 2 times to close the dataset properties.
Then, the states and counties parameters are cascaded.
Why does the “Attempted to divide by zero” error still
happen?
Answer
I have 2 decimal data fields (Field1 and Field2) in a dataset, and use the
expression with IIf function below to calculate the quotient. If the Field1 is not
zero, the divide expression within the true part will be executed. Otherwise, just
0 will be returned.
=IIf(Fields!Field1.Value<>0, Fields!Field2.Value/Fields!Field1.Value, 0)
However, why I am still getting "#Error" when Field1 is zero?
The error message is as follows:
[rsRuntimeErrorInExpression] The Value expression for the textrun
'Textbox6.Paragraphs[0].TextRuns[0].TextRuns[0]' contains an error:
Attempted to divide by zero
The cause of this error is that the IIf function always evaluates both the true part
and the false part, even though it returns only one of them. This means both the
true part and the false part need to be evaluated.
In order to resolve this issue, you need to use a nested IIf function to avoid the
zero-divisor in any rate.
=IIf(Fields!Field1.Value=0, 0, Fields!Field 2.Value/IIf(Fields! Field 1.Value=0, 1,
Fields! Field 1.Value))
After that, you will get the correct result whether Field1 is 0 or not.
Workaround
You can also use custom code to prevent errors caused by dividing by zero.
Select click Report Properties on the Report menu. Click the Code tab and enter

Reporting Services
91
the following code in the Custom Code box:
Function Divide(Numerator as Decimal, Denominator as Decimal)
If Denominator = 0 Then

Else
Return Numerator/Denominator

End Function
After that, set the expression to be:
=Code.Divide(Fields!Field2.Value, Fields!Field1.value)

How do I solve the issue - The configuration file contains an
element that is not valid?
Answer
The issue is probably caused by the rsreportserver.config configuration file
unexpectedly modified or some settings misconfigured. In this case the detailed
error message will indicate which element cause the problem. You can check the
detailed error message in the SSRS execution log. For example, there is the error
below:
appdomainmanager!DefaultDomain!1004!<DateTime>:: i INFO: Entered managed
ServiceMain in DefaultDomain.
configmanager!DefaultDomain!734!< DateTime>:: e ERROR: Error loading
configuration file: The configuration file contains an element that is not
valid. The Configuration element is not a configuration file element.

How do I keep only one vertical scroll bar in local report?
Answer
I have a local report with a long height; The problem is that there are two vertical
scroll bars on right hand like below. Specially, the scroll wheel does not work on
the inner scroll bar. Is there a work around for this?

Reporting Services
96
You can achieve this requirement in local report. Just type in below code in
code-behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
.........//other code
this.ReportViewer1.AsyncRendering = false;
this.ReportViewer1.SizeToReportContent = true;
this.ReportViewer1.ZoomMode = ZoomMode.FullPage;
.........//other code
}
}
Then you will get the report like below, you can see that there is only one vertical
scroll bar now, and it will never occur the scenario that the scroll wheel does not
work.

How do I Hide Export Options with Local Report?
Answer
Currently, this is a product limitation for customizing the export option directly of
the ReportViewer control.
However, as a workaround, we can use JavaScript to remove the Word and Excel
export options. Please refer to the steps below.
For ReportViewer 2008:
1. Preview the web page which contains the ReportViewer control.
2. Check the source code of page. Find the id of the <select> node which
contains the export options.
e.g. It is " ReportViewer1_ctl01_ctl05_ctl00" in my page.
3. In the ASPX file, add the JavaScript below:
<script type="text/javascript">
window.onload = function () {
var formatDropDown =
document.getElementById('ReportViewer1_ctl01_ctl05_ctl00');
if (formatDropDown != null) {
formatDropDown.remove(1);
}
}
</script>
For ReportViewer 2010:

Reporting Services
98
1. Preview the web page which contains the ReportViewer control.
2. Check the source code of page. Find the id of the <div> node which contains
the export options.
e.g. It is "ReportViewer1_ctl06_ctl04_ctl00_Menu" in my page.
3. In the ASPX file, add the JavaScript below:
<script type="text/javascript">
window.onload = function () {
var formatDropDown =
document.getElementById('ReportViewer1_ctl06_ctl04_ctl00_Menu');
var formats = formatDropDown.childNodes;
if (formatDropDown != null) {
formatDropDown.removeChild(formats[0]);
formatDropDown.removeChild(formats[1]);
}
}
</script>
Please correct the element id based on your web page. As a result, only the PDF
export option still exists.
How do I get the same page number in web page and PDF?
Answer
Reporting Services is designed to use 2 different rules in pagination:
1. Physical pagination is used to the print control and the TIFF and PDF
rendering extensions. It is controlled by the PageSize properties
2. Logical pagination is used to the HTML and GDI rendering extensions. It is
controlled by the InteractiveSize properties
However, if just specify the same size to PageSize and InteractiveSize, we will get
more pages in PDF or other physical formats due to the Margin properties of
Report are only applied in the physical pagination.
For example, if the InteractiveSize and the PageSize are both set to 8.5in x 11in
and the Margins are 1in, then the actual size of printing area in physical page is
6.5(8.5-1-1)in x 9(11-1-1)in. This leads to more pages are generated when render
in physical pagination.
In order to make the page numbers matches, we need to ensure the acutrul size
of printing area and the interactive size are the same. Please refer to the
equalities below:
1. Width(InteractiveSize) + Margin(Left) + Margin(Right) = Width(PageSize)
2. Height(InteractiveSize) + Margin(Top) + Margin(Bottom) = Height(PageSize)

Reporting Services
99
Since sometimes the PageSize is specified corresponding to a specific paper size
like A4 for printing, we suggest you to keep the PageSize to 8.5in x 11in and
adjust the InteractiveSize and Margins based on the equalities.

How do I pass a multi-value parameter into a report with
SQL Server Reporting Services (SSRS) Web Services API?
Answer
In Microsoft SQL Server Reporting Services (SSRS), in order to pass a multi-value
parameter through the Reporting Services Web services, you need to define the
same numbers of ParameterValue objects as the number of the values of the
multi-value parameter being past into the report. The Name property of these
ParameterValue objects must be specified same to the parameter name.
For example, you have a multi-value parameter named "ProductSubcategory" in
a report, and now you want to pass the values 1, 2 and 3 to the parameter, you
need to create a ParameterValue array which length is 3 and specify each one
with the same Name property value.
Below is a complete sample for your reference:
SRReportExecution2005.ReportExecutionServiceSoapClient rs = new

How do I pass a multi-value parameter to a dataset while
using LIKE operator in the WHERE clause?
Answer
1. Run the following code in your database to create a table valued function
which will be used to split a string into a table.
CREATE FUNCTION [dbo].[fn_String_To_Table] (
@String VARCHAR(max),
@Delimeter char(1),
@TrimSpace bit )
RETURNS @Table TABLE ( [Val] VARCHAR(4000) )
AS
BEGIN
DECLARE @Val VARCHAR(4000)
WHILE LEN(@String) > 0
BEGIN
SET @Val = LEFT(@String,
ISNULL(NULLIF(CHARINDEX(@Delimeter, @String) - 1, -1),
LEN(@String)))

Reporting Services
105
SET @String = SUBSTRING(@String,
ISNULL(NULLIF(CHARINDEX(@Delimeter, @String), 0),
LEN(@String)) + 1, LEN(@String))
IF @TrimSpace = 1 Set @Val = LTRIM(RTRIM(@Val))
INSERT INTO @Table ( [Val] )
VALUES ( @Val )
END
RETURN
END
2. In your repot, define a single valued and internal parameter called MPjoin,
then must set its default value using the expression
=Join(Parameters!rptParameter.Value,",").
3. Change your dataset query string like this:
SELECT T1.Col1,T1.Col2,T1.Title
FROM myTable T1 INNER JOIN fn_String_To_Table(@MPjoin,',',1) T2
ON T1.Title LIKE T2.Val+ '%'
4. Open the Dataset Properties, in the windows box, click Parameters to go to
the dataset Parameters page and make sure the @MPjoin value is from
@MPJoin or the expression =Join(Parameters!rptParameter.Value,",").
How do I preview a Subreport which is in another SSRS
project?
Answer
To preview the subreport, you have to first deploy your report project which
contains the subreport to your report server. If you choose "Go to Report" for
the subreport, you also need to deploy your main SSRS project to the report
server and then specify the relative path. In this scenario, the subreport's name
will not be displayed in the drop-down list of Select a report from the list when
you design the main report. You have to manually type in the relative subreport
path in the drop-down list. For example, your two SSRS projects are deployed to
the report server as following structure:

Reporting Services
106
Then you can configure the subreport settings as follows:
1. On your main report, right-click the textbox you want to add an action, and
then select Text box Properties...button.
2. Switch to the Action tab, type in the relative report path in the drop-down
list of Select a report from the list, such as ../DemoTest2/Product Detail:

Reporting Services
107
3. If the subreport has parameters, you can click the Add button to add
parameters into the parameter grid.
4. You need to hard code the Parameter Name in the Name drop-down list, as
these parameters are not contained in the name drop-down list.
5. In the Value drop-down list, select a value to pass to the subreport.
6. Repeat steps 3-5 to specify a value for each subreport parameter.
7. Click OK.
8. Deploy the report project and preview it.

Walkthrough: Control Dataset Query Dynamically based on
SSRS Report Parameters
Answer
Generally, using a parameterized query can filter data for a report dataset at the
source. When include query parameters in a query, Reporting Services
automatically creates report parameters that are connected to the query
parameters. This enables users to select the data based on a particular criterion,
such as values in a data field need to be greater than a specific value.
However, sometimes the criterion of the filter also depends on parameters
dynamically. For example, users can choose the comparison operator like >
(greater than) or < (less than) as report parameters to build the filter. This article
will walk you through the processes of using a dynamic query based on
parameters in a report.
The sample in this article uses the sample AdventureWorksDW2008 database.
The report displays the Product list containing Product Name, Standard Cost,
Dealer Price and List Price columns.
Add Data Source and Dataset
1. Create a new Report Server project and then add a blank report.
2. Add a new Data Source DataSource1 to connect the
AdventureWorksDW2008 database with the connection string like
Data Source=.; Initial Catalog=AdventureWorksDW2008
3. Add a new Dataset Dataset1. Specify the Data source to DataSource1 and
type in the following query
SELECT EnglishProductName, ListPrice, StandardCost, DealerPrice
FROM DimProduct
Add a Table
1. Add a table to the report body.
2. Add each data field in Dataset1 to the detail row of the table. It looks like
Add Parameters
1. Add a parameter FieldName with the Available Values below

115
Label Value
StandardCost StandardCost
DealerPrice DealerPrice
ListPrice ListPrice
2. Add a parameter Operator with the Available Values below
Label Value
> >
>= >=
="=" ="="
<= <=
< <
Please be aware that we need to specify an expression for the equal to item
rather than only use the equal sign.
3. Add a parameter Value and set its Data type to Float.
Modify the Dataset Query
1. Right click DataSet1 in the Report Data pane and select Dataset Properties.
2. In the Dataset Properties window, click the fx button beside the Query text
area.
3. Replace the query text to the expression below
="SELECT EnglishProductName, ListPrice, StandardCost, DealerPrice FROM
DimProduct WHERE " & Parameters!FieldName.Value &
Parameters!Operation.Value & CStr(Parameters!Value.Value)
Preview the report. Then, the Field Name, Operator and Value can be specified as
parameters to filter the query data dynamically.

Walkthrough: Assign Dataset Dynamically Created in Code
to your local report with ReportViewer
Answer
The Walkthrough: Creating a ReportViewer Report shows how to create a simple
table report in a Visual Studio Windows Forms application project based on a
predefined dataset and data table in the project. However, sometimes the
dataset need to be displayed is not the one you predefined, so the dataset
structure cannot be retrieved when you design the report. This article will walk
you through the processes of designing a local report and binding it to a
dynamically created dataset in code.
The sample in this article uses the sample AdventureWorksDW2008R2 database.

Reporting Services
129
The report displays the Product Category list containing both the category key
and category name columns.
Create a new Windows Forms application project
1. Open Visual Studio. On the File menu, point to New, and then select Project.
2. In the Installed Templates pane, select Visual C#.
3. Choose Windows Forms Application.
4. In the Name box, type SimpleReport.
5. In the Location box, enter the directory in which you want to save your
project, or click Browse to navigate to it.
6. Click OK.
Define a dataset for report designing
1. In the Project menu, select Add New Item.
2. In the Add New Item dialog, click DataSet. Type a name for the dataset and
click Add. The default name is DataSet1.xsd. This adds a new XSD file to the
project and opens the Dataset Designer.
3. From the Toolbox in the Dataset Designer, drag a DataTable control onto the
design surface.
4. Right click the DataTable and select Add -> Column.
5. Type in ProductCategoryKey as the Data Column name.
6. Add another column set the name to EnglishProductCategoryName
7. Save the DataSet1 file.
Add a new report definition file using the Report Wizard
1. From the Project menu, select AddNew Item.
2. In the Add New Item dialog box, choose Report Wizard.
3. In Name, type Product Category.rdlc and then click Add. A graphical design
surface opens behind the dialog box.
4. In the Dataset Properties page, in the Data source drop-down list, select
DataSet1 you created. The Available datasets box is automatically updated
with DataTable1 you created.
5. Click Next.
6. In the Arrange Fields page, drag both Category and Sales from Available
fields to the Values box.
7. Click Next twice, then click Finish.
This creates the .rdlc file and opens it in Report Designer. The tablix you designed
is now displayed in the design surface like this:
Product Category Key English Product Category Name

Reporting Services
130
[ProductCategoryKey] [EnglishProductCategoryName]
Add the ReportViewer control to your form
1. Click Form1.cs in Solution Explorer.
2. From the View menu, choose Designer.
3. From the Reporting section of the Toolbox, drag the ReportViewer control to
the form.
4. Open the smart tags panel of the ReportViewer1 control by clicking the
smart-tag glyph on the top right corner. Click the Choose Report drop-down
list and select SimpleReport.Sales Orders.rdlc.
Notice that a BindingSource is automatically created corresponding to which
point to DataSet1 as DataSource.
5. From the smart tags panel, click Dock in parent container.
Specify the dataset in code to the ReportViewer
1. Click Form1.cs in Solution Explorer and select View Code.
2. Add the following code to the Form_Load event. Since we need access SQL
Server Database, please also add using System.Data.SqlClient in the
namespace.
private void Form1_Load(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection("Data Source=.; Initial
Catalog=AdventureWorksDW2008R2; Integrated Security=True");
SqlDataAdapter da = new SqlDataAdapter("SELECT
ProductCategoryKey, EnglishProductCategoryName FROM
DimProductCategory", con);
DataSet ds = new DataSet();
da.Fill(ds);
ds.Tables[0].TableName = "DataTable1";
this.DataTable1BindingSource.DataSource = ds;
this.reportViewer1.RefreshReport();
}
In the code, we change the BindingSource to point the dataset created in the
code.
3. Build the project and run it. Then we can get the result like this:

Reporting Services
131
Besides dataset, you can also bind the datasource with a Linq result set but just
remember to keep the same data scheme as that defined in your report.

Walkthrough: Working ReportViewer with a complex
Business Object with a nested generic list type property as
data source for local reports
The MSDN document
http://msdn.microsoft.com/en-us/library/ms251784(v=VS.100).aspx shows a
good demo on how to use a business object with a ReportViewer control for local
processing. This is a simple scenario, however sometimes the situation becomes
complex when there is a nested generic List type property defined in the Product
class. This article will dig further on handling this complex business object
scenario.
Perform the following steps to create a complex business object, design a local
report, and display it a ReportViewer control in your .NET Windows Form or Web
Form application.
Create a business object as a data source
1. Create a Windows Form project in Visual Studio and then create a new class
with the file name BusinessObject.cs.
2. Replace the default code with the code:
public class Product
{
private string m_name;
private int m_price;
private List<int> m_styles;
public Product(string name, int price, List<int> styles)
{
m_name = name;
m_price = price;
m_styles = styles;
}
public string Name
{
get
{
return m_name;
}
}
public int Price

Reporting Services
141
{
get
{
return m_price;
}
}
public List<int> Styles
{
get
{
return m_styles;
}
}
}
public class Merchant
{
private List<Product> products;
public Merchant()
{
products = new List<Product>();
}
public List<Product> ProductList
{
get
{
return products;
}
}
public void AddProduct(Product product)
{
products.Add(product);
}
}
3. Build your project. This creates an assembly for the object, which you will
later use as a data source for the report.
Add a report to the project
1. From the Project menu, select Add New Item.
2. In the Add New Item dialog, select Report. Type a name for the report and
click Add. This launches the Report Wizard with the Data Source
Configuration Wizard.

Reporting Services
142
3. In the Choose a Data Source Type page, select Object and click Next.
4. In the Select the Data Objects page, expand the class hierarchy under
BusinessObject until you see Product in the list. Select Product and click
Finish. You now return to the Report Wizard. Notice that the new data source
object is added to your project in Solution Explorer.
5. Click Next, and then click Finish to quickly finish the report composing. Now
you can see your local report generated like this.
Add a ReportViewer control to your Windows Form
1. Drag a ReportViewer control to your Windows form or Web form.
2. Select the ReportViewer control, and open the smart tags panel by clicking
the triangle on the top right corner. Click the Choose Report drop-down list
and select the report you just designed. For example:
Notice that a BindingSource is automatically created corresponding to each
object data source used in the report.
Add code to display your report with ReportViewer control
1. Add the following code to the Form_Load event:
Merchant merchant = new Merchant();
merchant.AddProduct(new Product("Bike", 20, new List<int>() { 1,
2, 3 }));
merchant.AddProduct(new Product("Towel", 10, new List<int>()
{ 90, 60, 75 }));
this.BindingSource.DataSource = merchant.ProductList;
this.reportViewer1.RefreshReport();
2. Build your project and run it.
3. After you run your application, you will find that the Styles field could not be
correctly displayed:

Reporting Services
143
WHAT IS WRONG?
If you look at the output information in Visual Studio, you can find the
following warning:
Warning: The Value expression used in textbox 'Styles'returned a data type
that is not valid. (rsInvalidExpressionDataType)
The error is caused by the fact that the Fields!Styles.Value is actually a
List<int> type object which cannot be directly displayed in the report.
Modify your report for correct display
The following steps will correct the problem and display the styles into a string
with the format like "1, 2, 3":
1. Double click your report to open it in designer view in Visual Studio.
2. Click the top Report menu
3. Click Report Properties
4. Switch to the Code tab and input the following code:
Public Function GetListItems(intList As
System.Collections.Generic.List(Of Integer)) As String()
Dim intArrayStr As String() = Array.ConvertAll(Of Integer,
String)(intList.ToArray(), New Converter(Of Integer,
String)(AddressOf Convert.ToString))
Return intArrayStr
End Function
5. Click OK to return to the report
6. Replace the Styles field value =Fields!Styles.Value by the expression
=Join(Code.GetListItems(Fields!Styles.Value),",").
7. Build and run your project again. Then you can get the result like this:

How do I set a flat file name for flat file connection
manager dynamically?
Answer
You can implement this requirement with these steps:
1. Create a package scope variable“FileName”, and set its default value to
“test.txt”.
2. In your SSIS package, locate your existing connection manager. For example,
“TestFlatConnectionManager”, and add the following expression for the
ConnectionString property:
"C:" + @[User::FileName]
Save the package, and the TestFlatConnectionManager will get the file name
dynamically.

147
How do I use dynamic T-SQL in Lookup?
Answer
1. Create a package scope variable "SQLVariable", change its type to string.
2. Open the Lookup transformation, type a default SQL clause for it.
3. Select the data flow task that includes the Lookup and go to its properties.
Click on the ellipsis (…) against Expressions, use the expression
"@[User::SQLVariable]" for [LookupName].[SqlCommand] property.
Thenyou can dynamically change the SQL clause for the Lookup by modifying the
value of the variable "SQLVariable".

148
How do I use lookup transformation to load data
incrementally?
Answer
The Lookup transformation component will help for this scenario. You can refer
to the following steps:
1. Create a test table and add some test data.
CREATE TABLE dbo.SourceTable
(ProductID int NOT NULL
,Name varchar(10) NULL)
Go
CREATE TABLE dbo.DesTable
(ProductID int NOT NULL
,Name varchar(10) NULL)
Go
Insert into SourceTable(ProductID,Name) values(1,'a')
Insert into SourceTable(ProductID,Name) values(2,'e')
Insert into SourceTable(ProductID,Name) values(3,'c')
Insert into DesTable(ProductID,Name) values(1,'a')
Insert into DesTable(ProductID,Name) values(2,'b')
2. Drag a Data Flow task onto the control panel, and double-clickthe “Data Flow
Task”.
3. From the toolbox, drag an OLE DB Source and connect to the table
“SourceTable”.
4. Drag a Lookup transformation on to the data flow panel, and create a
connection from the OLE DB Source to it. Double click the Lookup component
to open the Property editor, choose “Ignore failures” for “specify how to
handle rows with no matching entries”. In the Connection tab, choose the
connection manager and select the table “DesTable”. Then click the Columns
tab, map the columns “ProductID” between the SourceTable and the
DesTable, and check all the checkboxes in the destination.
5. Modify the output alias like this:ProductID->De_ProductID
andName->De_Name. Click the“Error Output” tab,andselect the“Ignore
failure item” for error column.
6. Drag a Conditional Split, and connect the Lookup to it with matched output.
Edit the Conditional Split, and add the following two outputs.
NewRow: ISNULL(De_ProductID)
Changes: (ISNULL(De_ProductID)==False) && (Name != De_Name)

149
Note: For those records not found in the destination table, the column value
of De_ProductID in the output table is NULL, which also means that these
records in the source table are newly added. Else if the Name values in the
source table do not match corresponding values in the destination table, it
means these records in the source table are changed. If you have multiple
columns, you may consider adding a timestamp column to save the update
time automatically.
7. Now you can incrementally load data by inserting the new rows into your
target table and update changed records also from the two outputs from the
Conditional Split component. Drag a SQL Server Destination for inserting new
data and an OLE DB Command for updating records to the panel.
a. Connect the Conditional Split to the SQL Server Destination
with“NewRow”output. Then connect the Conditional Split to the OLE DB
Command with “Changes” output.
b. Edit the SQL Server Destination, connect it to the table “DesTable”.
c. Double click the OLE DB Command, set the Connection Manager column
to your destination connection manager.
d. Switch to the "Component Properties" tab, and input the following T-SQL
clause to the SQLCommand field:
UPDATE dbo.DesTable
SET Name = ?
WHERE ProductID = ?
e. Click the Column Mappings tab, and you can find two columns
automatically generated in the Available Destination Columns, Param_0
and Param_1. According to the parameters sequence showed in the
T-SQL, you can connect Name to Param_0 and ProductID to Param_1.
8. Save and execute the package.

How do I create a folder for SSIS package in MSDB with
T-SQL?
Answer
Yes, you can directly insert a record into the user table dbo.sysssispackagefolders
in your msdb database with the T-SQL statement as follows:
INSERT INTO dbo. sysssispackagefolders (
folderid
,parentfolderid
,foldername)
VALUES (NEWID(), '<Parent folder GUID>', '<Folder name>')
For example, if you want to create a folder named “Packages” under the
MSDB folder, you can run the following T-SQL:
INSERT INTO dbo. sysssispackagefolders (
folderid
,parentfolderid
,foldername)
VALUES (NEWID(), '00000000-0000-0000-0000-000000000000','Packages')

151
How do I resolve the error "Connection is busy with results
for another command"?
Answer
The error message usually indicates that there are multiple parallel running SSIS
tasks sharing a same connection and that you set your connection
manager’sRetainSameConnection property to True. If one task has not finished,
but the others are sending requests on the same connection, this issue may
occur.
To resolve this issue, you can simply change the property value to False. If you
want some tasks to share a same connection, it is recommended that you have
these tasks executed in sequence. For parallel tasks with the same data source, it
is recommended that you set it to False or create separate connection managers
for them.

152
How do I programmatically create a Transfer SQL Server
Objects task?
Answer
You can use a Script Task to add a Transfer SQL Server Object Task and set the
TableList property with StringCollection.
1. Create a package scope variable “TableName” to hold table names, change
its type into Object.
2. From the toolbox, drag an Execute SQL Task to the Control Flow panel.
3. Double-click that task to edit it, change the “Resultset” value to “Full Result

How do I execute a stored procedure with a return value
and an output parameter in an Execute SQL Task?
Answer
The parameters settings for a stored procedure in an Execute SQL Task depend
on your connection type. For OLE DB connection and ADO.NET connection, the
parameters settings are different. Assume that you have stored procedure like
this:
CREATE PROCEDURE AddDictionary
(
@name nvarchar(50),
@id uniqueidentifier output
)
AS
DECLARE @retval int
SET @retval = 0
IF EXISTS(SELECT * FROM DICTIONARY WHERE [NAME]=@name)
BEGIN
SELECT @retval = -1
END
ELSE
BEGIN
SELECT @id=newid()
INSERT INTO DICTIONARY VALUES(@id,@name)
END
RETURN @retval
Now in your SSIS package, first create three variables in your SSIS package. Click
the SSIS menu, click Variables, and create the variables User::ItemName with
String type and a default value “Test”, User::ItemId with Object type, and
User::ReturnValue with Int32 type and a default value 0.
If your connection type is OLE DB connection, you can refer to the following
steps to configure your Execute SQL Task:
1. Double click your Execute SQL Task, input the following statement to the
SQLStatement field:
exec ? = AddDictionary ?, ? output
2. Choose ResultSet to None and SQLSourceType to Direct Input.

155
3. Switch to the Parameter Mapping panel, click Add to add the three variables
created above to map the parameters in the stored procedure.
4. You can configure the settings as the following table:
Variable Mapping Direction Data
Type
Parameter
Name
Parameter
Size
User::ItemName Input NVARCHAR 1 50
User::ItemId Output GUID 2 -1
User::ReturnValue ReturnValue Int32 0 -1
Note that the ParameterName values are numeric and zero based. You need to
set the name starting from 0 according to the parameters occurrence sequence
in the SQLStatement.
If you are using ADO.NET connection, the steps are different:
1. Double click your Execute SQL Task, input the following statement to the
SQLStatement field:
declare @retval int
exec @retval = AddDictionary @itemname, @itemid output
2. Choose ResultSet to None and SQLSourceType to Direct Input.
Switch to the Parameter Mapping panel, click Add to add the three variables
created above to map the parameters in the stored procedure as follows:
Variable Mapping Direction Data Type Parameter
Name
Parameter
Size
User::ItemName Input NVARCHAR @itemname 50
User::ItemId Output GUID @itemid -1
User::ReturnValue ReturnValue Int32 @retval -1
Note that the ParameterName values are same as the parameter names
specified in your SQLStatement. But you need to explicitly declare the parameter
for the return value.
After you are clear about these steps, you can successfully execute your stored
procedure with an Execute SQL Task.

How do I use the Fuzzy Grouping transformation?
Answer
The Fuzzy Grouping transformation indeed can look through a list of similar text
and group them together.
For example:
EMPID,TITLE,LNAME
1,CEO,Jack
2,Ceo,Jack
3,CIO,Jimmy
We can see that the meanings of the “CEO” and “Ceo” are the same except for
the case sensitivity. So we need to group and clean those two rows.
You can do this by referring to the steps below:
1. Create a flat file named “FuzzySampleData.txt”, and copy the above data
into it.
2. Create a Flat File Connection under the Connection Manager panel. Name it
“FuzzyGroupConn” and set the filename to the path of the file
“FuzzySampleData.txt”.
3. Drag a Flat File Source to the Data Flow panel and configure it to use the
FuzzyGroupConn connection.
4. Drag a Data Conversion component to the panel, connect the Flat File Source
to it and convert the data type of the TITLE column to DT_WSTR, and type
the output alias "TITLENEW".
5. Drag a Fuzzy Grouping component to the Data Flow panel. Connect the
output of the Data Conversion to the Fuzzy Grouping. Go to the Fuzzy
Grouping’s property editor, select the Column tab, choose “TITLENew” as
input column. Then go to the “Advanced” tab, and set the Similarity
threshold to .50.
6. Drag an OLE DB Destination to the Data Flow Panel, connect the Fuzzy
Grouping component to it, right click the green connection line, click Data
Viewers…, and click the “Add…” button to add a data viewer. The results look
like this:
_key_in _key_out _score EMPID TITLE NAME TITLENEW TITLE_CLEAN _Similarity_TITLENEW
2 1 1 2 Ceo Jack Ceo CEO 1
1 1 1 1 CEO Jack CEO CEO 1
3 3 1 3 CIO Jimmy CIO CIO 1
From the _key_out and TITLE_clean columns, you can find that the data is
cleaned and grouped by similar title values.

157
Note: If you could not successfully execute the package due to a code page issue,
you can change the property “AlwaysUseDefaultCodepage” of your SQL Server
Destination component to True.

How do I use Integration Services to achieve Push-mode
processing for Analysis Services?
Answer
Usually when you process a cube, the SSAS service will send SQL queries to the
underlying data source so as to load data into the cube. This is a typical
pull-mode processing. But in some cases, the data sources are non-regular
databases or plain text files, which will cause difficulties to use pull-mode
processing since you could not use any type of SQL. In this case, you may want to
use a push-mode processing.
Microsoft SSIS provides this function. It can fetch data from underlying data
sources and pushes the data into SSAS cubes directly.
For example, the internet order quantity of the calendar year 2001 is: 1031. But
for some reason, you need to add a new record from txt file to the cube:
ProductKey OrderDateKey DueDateKey ShipDateKey CustomerKey PromotionKey
CurrencyKey SalesTerritoryKey SalesOrderNumber SalesOrderLineNumber
RevisionNumber OrderQuantity UnitPrice ExtendedAmount UnitPriceDiscountPct
DiscountAmount ProductStandardCost TotalProductCost SalesAmount TaxAmt
TaxAmt Freight CarrierTrackingNumber CustomerPONumber
310 20010701 20010713 20010708 21768 1 19 6 SO75124 1 1 1 3578.27 3578.27
0 0 2171.2942 2171.2942 3578.27 286.2616 89.4568 NULL NULL
1. Create a package, drag and drop a "Data Flow Task" on to the Control Flow
tab. Copy and paste above record to a txt file.
2. Switch to Data Flow, create a "Flat File Source" pointing to the txt file. Select
the option "Column names in the first data row", keep the other default
setting and then switch to the columns tab, review the data to ensure you
can access to that file without any problem.
3. In Flat File Source Editor, select the option "Retain null values from the
source as null values in the data flow".
4. Drag and drop a "Partition Processing Destination" on to the Control Flow
tab, connect "OLE DB Source" to "Partition Processing Destination", double
click the "Partition Processing Destination", and then create a data Source
pointing to the Adventure Works DW 2008 multidimensional database.
5. Select partition Internet_Sales_2001 as target object, select ‘Add’ as
processing method for testing only.
6. Map the input columns with the partition attributes. You should map every
attribute to the input columns, for example:

159
7. Run the package, then check the internet order quantity of calendar year
2001, and it should be 1,014 now.

How do read data from Excel 2007 with Integration
Services 2005?
Answer
To read data from Excel 2007, you can try the following steps:
1. Ensure you have installed the provider “Microsoft Office 12.0 Access
Database Engine OLE DB Provider”
2. Create an OLE DB source, double click on the OLE DB Source and then create
an OLE DB connection manager.
3. Select “Microsoft Office 12.0 Access Database Engine OLE DB Provider” as
the provider, and enter the full path of the file for “Server or file name”.
4. Switch to the “All” tab, specify the extended properties, and then enter
“excel 12.0” for the property “Extended properties”. Click the button “Test
Connection”, ensure you can access to the Excel file.
5. After create the Connection Manger, in OLE DB Source Editor, select “Table
or view” as the access mode, and then select the Excel sheet in the list
“Name of the table or the view”. Then Click the “OK” button.

How do I upgrade my DTS packages to SSIS 2008 packages?
Answer
SSIS is a revolutionary change to DTS. A lot of things have been changed.
Currently there is no way to directly upgrade a complex DTS package to a SSIS
package, instead you can only migrate a DTS package to a SSIS package by using
DTS Package Migration Wizard, but there are still many known issues for the
migration process. It may be fine to migrate some simple DTS packages, but for
complex ones, the migration process may have problems.
If you decide to use DTS Package Migration Wizard to migrate the DTS packages,
after the migration you still have a lot of work to do, recreating some
components, reconfiguring some settings and performing tests.
If you have many DTS packages, the way I recommend is you keep on using your
old DTS packages but just wrap each DTS package with a SSIS package, which
means you can use the task "Execute DTS 2000 Package Task" in SSIS package to
execute your existing DTS package.
If the number of DTS packages is low and the packages are not very complex, you
may consider creating new SSIS packages to replace them.
Please refer to this article for more detailed information:
Migrating Data Transformation Services Packages
If you want to know of some third-party tools for the migration, you may try this
one, DTS xChange developed by the MVP Brain Knight. Please note that for third
party tools, Microsoft has no warranties of them. We post the information here
just for your reference. If you have any questions on third party tools, please
contact the vendors.

How do I troubleshoot SSIS packages failed execution in a
SQL Agent job?
Answer
When you see a SSIS package fails running in a SQL Agent job, you need to first
consider the following conditions:
1. The user account that is used to run the package under SQL Server Agent
differs from the original package author.
2. The user account does not have the required permissions to make connections
or to access resources outside the SSIS package.
You can find the detailed information in this KB article:
An SSIS package does not run when you call the SSIS package from a SQL Server
Agent job step
You can check SQL Server Agent’s activity logs, Windows Event logs and SSIS logs
to get more clues. Also the tool Process Monitor is helpful to track the cause of
registry or file access related issues.
The following 4 issues are common encountered in the SSIS forum. We also
would like to list them here for your reference:
1. The package's Protection Level is set to EncryptSensitiveWithUserKey but your
SQL Server Agent service account is different from the SSIS package creator.
2. Data source connection issue.
3. File or registry access permission issue.
4. No 64-bit driver issue.
Package Protection Level issue
For the 1st issue, you can follow the following steps to troubleshoot this issue:
1. Check what the Protection Level is in your SSIS package.
2. If the Protection Level is set to EncryptSensitiveWithUserKey, check the
Creator in your SSIS package and compare it with the SQL Server Agent
Service account.
3. If the Creator is different from the SQL Server Agent Service account, then
the sensitive data of the SSIS package could not be correctly decrypted,
which will lead to the failure.
A common solution to this issue is that you create a proxy account for SSIS in SQL
Server Agent and then specify the proxy account as the "Run as" account in the
job step. The proxy account must be the same as the SSIS package creator. You
can refer to this article for how to create a proxy account:

163
How to create a proxy account
You can also change the SSIS package protection level to
EncryptSensitiveWithPassword and specify the password (/P XXXX) in the
command line in the job step. For the command parameters, you can refer to
this article:
Dtexec utility
Besides you can import your SSIS package into your SQL Server MSDB database
via SQL Server Management Studio (connecting to Integration Services). When
you import the package to MSDB, you need to set the ProtectionLevel to "Rely
on server storage and roles for access control". After that, add your SQL Server
Agent Services account to be a user of MSDB with the db_ssisadmin role. Then
connect to your SSIS in SSMS again, right click your SSIS package, click Package
Roles, and set both the ReaderRole and Writer Role to db_ssisadmin.
Data Source Connection Issue
For the 2nd data source connection issue, it usually happens when you are using
Windows Authentication for your data source. In this case, you need to make
sure that the SQL Server Agent Services service account or your Proxy account
has the permission to access your database.
File or Registry Key Access Issue
For the 3rd file or registry access permission issue, if you know which file or
folder your SSIS package need to make sure that your SQL Server Agent Services
service account or your Proxy account has the permission to access the file or
folder. If you are not very sure of this, you can run SQL Server Process Monitor to
monitor your SQL Server Agent Services process and dtexec process when you
start running the job. You can analyze the trace to check if there is any ACCESS
DENIED message. You can download Process Monitor here:
Process Monitor
http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx
64-Bit Driver Issue
For the 4th issue, this usually happens on a 64-bit server since there is no
corresponding 64-bit driver in a 64-bit process. Think about that when your SSIS
package is accessing Excel or Access database file while there is no related 64-bit
Jet driver, the job of executing your SSIS package will fail. To resolve this issue,
before SQL Server 2008, you need to use 32-bit DTEXEC utility in your SQL Server
Agent job to execute the SSIS package. In SQL Server 2008, you have a better
choice, using the option “Use 32-bit runtime” under the tab “Execution options”
of your job step with the “SQL Server Integration Services Package” type.

164
How do I track the error message when my SSIS package
failed execution?
Answer
Generally if you do not apply any logging functions to your SSIS package, you
may only find very few error messages via Windows Event logs or console output.
But if your SSIS package has logging functions enabled, that is a different story.
Commonly there are five places you can work with:
1. Windows Event Log & Job History
2. Logs from SSIS Logging Audit
3. Logs from SSIS Event Handler
4. Logs from the SSIS components
5. Logs from underlying data sources
Windows Event Log & Job History
If your SSIS package runs with a SQL Agent job, you can first track the error
message in Windows Event Logs and SQL Server Agent job history.
Logs from SSIS Logging Audit
The first method usually displays general error messages. If you need to probe
more detailed information, you can enable SSIS logging audit to output the error
messages to a text file, Windows Event log, SQL Server Profiler trace, XML file or
the SQL Server database table sysssislog. In SSIS package, you can do this by
configuring SSIS log providers.
Integration Services Log Providers
Logs from SSIS Event Handler
You can add more custom error handling logics under the Event Handler panel.
You can define the error event handler at both the package level and the control
flow task level. It is a powerful feature and easy for you to create custom event
handling logic for different events.
Integration Services Event Handlers
Logs from SSIS components

165
You can also implement your custom logging logic in a SSIS Script Task or a Script
Component. For example, write some variable values or data into a text file
during the SSIS package execution.
Logs from underlying data sources
If from your SSIS logs or Windows application logs, you find some overall error
messages related to your underlying data sources, you may need to drill into the
details by observing the error logs of your data source. In SQL Server, this is SQL
Server error logs which are by default located in Program FilesMicrosoft SQL
ServerMSSQL.nMSSQLLOGERRORLOG

166
How do I troubleshoot a connection error regarding
DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTION
MANAGER ?
Answer
Many issues may cause this error message. When this issue happens, it usually
lacks of adequate information for troubleshooting. The following summarizes
most common scenarios and resolutions on this issue so that you can have the
general perspectives to troubleshoot this issue.
1. Incorrect provider for connection
This issue usually happens when you choose a provider which is not mapped to
the correct version that the process needed. There are two typical scenarios:
A.Lack of 64-bit provider
B.Lack of client binary installed
For A, a common issue to see is that there is no 64-bit Jet provider, though you
can choose the provider at the design time, but when you run it under 64-bit
process, the execution will fail.
To resolve this issue, you need to use 32-bit DTEXEC to run your SSIS package. If
you are in a job, set the job step to run the 32-bit dtexec to execute your SSIS
package. If you are in BIDS, you need to change the SSIS Project property (under
Debugging) "Run64BitRuntime" to False. But please aware that this setting is
only for debugging purpose in BIDS.
For B, it often happens for third party data sources like Oracle, AS/400 DB2 etc.
When you deploy your SSIS package to a target server, please remember to
install and configure the client binaries.
2. Incorrect connection parameters settings
This issue often happens when you specify wrong connection parameters or
explicitly specify a password in the connection string in your SSIS package. You
need to first make sure that every parameter you set in the connection string
does not have any typo error. For the password issue, it is caused by the fact that
your SSIS package does not save the password in the package.
If you are using a connection to SQL Server, there is an option "Save my
password" under "Use SQL Authentication" on the connection property window.
But for other types of data source connections, there might be no such option.
You may use a configuration file to save your password. However there is a
security risk since the password in a configuration file is unencrypted. A safer

167
way is to save the sensitive information in your SQL Server database so that you
can provide more restrictions to access the password information, or you can
change the package’s protection level to EncryptSensitiveWithPassword or
EncryptSensitiveWithUserKey.
3. Sensitive data for the connection could not be correctly decrypted
This issue usually happens when you execute your SSIS package in a SQL Server
Agent job. By default, your SSIS package chooses EncryptSensitiveWithUserKey
as the ProtectionLevel. If your SQL Server Agent Services service account is
different from the SSIS package creator, it cannot decrypt the sensitive data
correctly and this will fail the connection. You can refer to the FAQ "How do I
troubleshoot SSIS packages failed execution in a SQL Agent job?" for more
information.
4. Oracle data provider limitation
Another common scenario happens when you use Microsoft OLE DB Provider for
Oracle or Microsoft ODBC Driver for Oracle to connect to Oracle9i or later
version database. There are many limitations which can be found in this KB
article,http://support.microsoft.com/kb/244661. It is recommended that you use
Oracle OLE DB Provider for the Oracle 9i or later versions.
But you still need to be aware of this known issue on the connection parameter
"Initial Catalog":
You get "DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER"
error message when using Oracle connection manager in SSIS

168
How do I troubleshoot SSIS package hanged for running?
Answer
There might be various reasons to cause a SSIS package hanged for running and
generally for a hang issue, there is no log information helpful for diagnostics.
These are the difficulties of troubleshooting hang issues. In this FAQ, we would
like to give you three common aspects to help you perform self-troubleshooting:
1. Resource bottleneck
2. Blocking or Deadlock
3. Poor performance query
Resource Bottleneck
Generally resource bottleneck includes bottlenecks of memory, processor,
physical disk or network interface. You can run Performance Monitor
(perfmon.exe) to collect the trace with the following counters:
Processor: %Processor Time
Processor: %DPC Time
Processor: %Privileged Time
Processor: Interrupts/sec
Memory: Available Bytes
Memory: Pages/sec
Memory: Page Faults/sec
Memory: Committed Bytes
PhysicalDisk: Avg. Disk Queue Length
PhysicalDisk: Avg. Disk Read Queue Length
PhysicalDisk: Avg. Disk Write Queue Length
PhysicalDisk: Disk Reads/sec
PhysicalDisk: Disk Writes/sec
PhysicalDisk: Disk Transfers/sec
Network Interface: Bytes Total/sec
Network Interface: Bytes Sent/sec
Network Interface: Bytes Received/sec
Network Interface: Current Bandwidth
Process: *

169
System: Processor Queue Length
System: Threads
(*) means all the related performance counters
Memory pressure
When you observe that there is not much available memory and the Pages/sec is
over 20, it indicates that you are probably facing a memory bottleneck.
You can check or try the following methods to reduce memory usage:
• Check if your SSIS package is trying to load a large amount of data with a Sort
transformation that is memory intensive, if there is a sort transformation in your
SSIS package, consider removing it and put the sort operation to your database
level.
• Avoid including unnecessary columns from your source component
• Stop all unnecessary applications or services to release some memory;
• Reduce the values of DefaultBufferMaxRows and DefaultBufferSize.
• If your SSIS package uses SQL Server data source, try configuring "min server
memory" and "max server memory" on your SQL Server instance so as to restrict
the memory usage by SQL Server;
• Split your SSIS package into multiple packages with each one only transferring
small amount of data.
• If your server is 32-bit with 4GB memory, you can enable /3GB switch in your
system boot file so as to assign 1GB more memory to applications running in user
mode.
If these steps still do not help, consider adding physical memory to your
machine.
High CPU
If you encounter high CPU issues during the package execution, you can identify
which process is intensively using the CPU by observing the Process: %Processor
Time counter or simply using Task Manager to sort the process by CPU. If the
high CPU is for dtexec process, you need to check if there are too many
concurrent threads for SSIS tasks. If so, try reducing the package property
MaxConcurrentExecutables value or combining parallel tasks in sequence to see
if this situation will be improved.

170
If your SSIS package is accessing a local SQL Server instance, you need to check if
the high CPU is caused by a nonoptimal query plan. You can refer to this article
on further
troubleshooting,http://msdn.microsoft.com/en-us/library/cc966540.aspx.
If the high CPU is caused by another process, you need to observe the
relationship between the process and your SSIS package, and evaluate if you can
temporarily stop the process or schedule to run your SSIS package in a different
time.
Disk bottleneck
If you see PhysicalDisk: Avg. Disk Queue Length >2, it usually indicates that you
are probably facing a disk I/O bottleneck issue. You need to contact your
hardware vendor to perform I/O stress test and diagnostics.
Network bottleneck
For NIC, you can check the network utilization by observing the counters
Network Interface: Bytes Total/sec and Network Interface: Current Bandwidth. If
the average value of (bytes total/sec) / current bandwidth is over 70% during
your SSIS package execution, it means that your NIC may encounter a bottleneck
and you may consider replacing it with a faster NIC.
In addition, you can run Network Monitor (netmon.exe) to monitor the network
traffic on your NIC, if you see a significantly large number of TCP re-transmissions,
it could indicate that your network condition is not healthy and it may cause
intermittent connection issue.
You can also refer to this article for using perfmon to diagnose performance
issues:
http://technet.microsoft.com/en-us/magazine/2008.08.pulse.aspx
Blocking & Deadlock
If you do not encounter resource bottleneck problems, you can check if there are
blocking/deadlock issue. Blocking issues may happen in the underlying data
sources, files or script tasks.
For SQL Server, there are a lot of methods to monitor blocking and deadlock
issues. A common way is to use SQL Server Profiler to capture the trace of

171
Locking events. You can also refer to this KB article to monitor blocking issue:
You can also enable the trace flags 1204 and 1222 on your SQL Server to check if
there is any deadlock happening:
DBCC TRACEON(1204, 1222, -1)
Enabling these trace flags will output deadlock information to your SQL Server
error logs and you can find the detailed information from your SQL Server Error
log. This article describe more information about deadlock:
When you identify blockers, you can kill them with the KILL command. Blocking
and deadlock are very common for concurrent access and sometimes it is by
design and cannot be avoided, but you can refer to the following article to
minimize the blocking opportunity:
http://technet.microsoft.com/en-us/magazine/2008.04.blocking.aspx
For file access, avoiding concurrent access usually can resolve blocking issues.
For Script task, a common blocking issue happens on concurrently
reading/writing variables. You need to use VariableDispenser.LockForRead or
VariableDispenser.LockForWrite for read or write variables. Remember to
explicitly call Variables.Unlock() to release the locks once you finish handling the
variables. More information can be found here:
Variables.Unlock Method
http://msdn.microsoft.com/en-us/library/microsoft.sqlserver.dts.runtime.variabl
es.unlock.aspx
Poor Performance Query
If through your observation, you find that your SSIS package is hanging at the
step of an Execute SQL Task or other tasks running some queries to your SQL
Server database, in this case, you can use SQL Server Profiler to capture the trace
of the queries and identify the cause of the issue by analyzing the profiler trace
file. Then you can use Database Engine Tuning Advisor (DTA) to analyze the
queries and get some suggestions from DTA on how to improve the query
performance such as creating missing indexes. You can refer to this article for
more information:

172
Using DTA is a simple way to help you perform quick tuning on your queries.
Besides if your database is a large database with busy CRUD operations, you may
need to pay special attentions on your database statistics and fragmentations. If
database statistics are not updated in-time, the cached query execution plan
may be out and thus is not the best optimized one for the current query, it is
recommended that you schedule a job to timely update statistics on those heavy
tables.
Also huge fragmentations also degrade query performance, you can run the DMF
sys.dm_db_index_physical_stats on your table indexes to check the value of
avg_fragmentation_in_percent, if it is between 5% and 30%, try re-organizing
your indexes, if it is larger than 30%, try rebuilding indexes.
If you want to know more detailed information of troubleshooting SQL Server
performance issue, you can refer to the following two articles:
Troubleshooting Performance Problems in SQL Server 2005
Troubleshooting Performance Problems in SQL Server 2008
If you have a large amount of data to be transferred, it is recommended that you
enable the FastLoad option which requires a TABLE LOCK on the destination
table. If your destination is SQL Server, please use SQL Server Destination for the
best performance.
Other
Some problems are caused by known issues which are addressed in the latest
SQL Server Service Packs. It is recommended that you apply the latest service
pack before you perform in-depth troubleshooting.
If you still cannot resolve this issue after taking the above jobs, please collect a
hang dump file with ADPlus and contact Microsoft Customer Support Services for
further assistance.

How do I use SSIS to completely transfer my database
including logins, users, and permissions from one server to
another server?
Answer
This is a very common asked question, but there is indeed no easy way for a fully
automatic process. Though SSIS provides some methods like Transfer SQL Server
Login Task, Transfer SQL Server Database Task and Transfer SQL Server Database
Object Task, when you perform a real transfer, you will find that transferring
logins, users and user permissions is always a head-ache due to the security
design.
Many people usually need to manually reset the login passwords, recreate logins
and assign database roles to users after they create a SSIS package with those
aforementioned tasks for transfer. Here are the steps:
1. In SSIS, drag Transfer SQL Server Login Task to the Control Flow. Double click
on it to open the property editor, set the connections, choose the logins you
want to transfer and set the options “IfObjectExists” and “CopySids” per
your favorite.
Note: You can choose "IfObjectExists" to Skip if there are already duplicated
logins existing on the target server. In this case, choosing Overwrite may
cause errors during execution.
Setting CopySids to True is helpful for transferring Windows domain user
accounts when the two servers are in the same domain. If they are in
different domains, you need to re-create the logins later.
2. Drag a Transfer Database Task to the Control Flow panel. Double click it to
open the property editor, choose the Method of Source Database to
“DatabaseOnline”, and set the connections and destination database.
3. Link the two Tasks together from Transfer Login Task to Transfer Database
Task.
4. Save and Execute the SSIS package.

5. After that, connect to the target server, manually change the login password
for those transferred SQL logins since for SQL logins, after the transfer, their
passwords have been reset with random values.
6. As step 1 mentioned, if the Windows login account is in different domain,
you need to drop and recreate the logins.
7. Manually assign database roles for users.
To automate the whole process within a SSIS package, you need to consider
integrating the steps 5 to 7 to your SSIS package. Before you transfer your
database, you can first script out the logins/passwords, login permissions to a
logins.sql script file and user role permissions to another users.sql file, then you
can implement an automatic transfer with one Execute SQL Task (executing the
logins.sql script file) for creating logins/passwords on the target server, one
Transfer Database Task for transferring database objects to the target server as
the step 2, and one Execute SQL Task (executing the users.sql script file) to assign
users’ permissions.

How do I create and deploy a SSIS custom task?
Answer
Regarding the creation of a SSIS custom task, you can first start with the
following article and its related articles:
Create a Custom Task
There is also a good example "HelloWorldTask" in SSIS team blog which you can
reference:
http://blogs.msdn.com/mattm/archive/2008/07/18/creating-a-custom-task-with
-a-default-ui.aspx.
To easily deploy your SSIS custom task and use it immediately in your BIDS, you
can add the following script to your project's PostBuild event:
"C:Program FilesMicrosoft SDKsWindowsv6.0ABingacutil.exe" /if
"$(TargetPath)"
copy $(TargetFileName) "C:Program Files (x86)Microsoft SQL
Server100DTSTasks"
In this way, once you build your project, your custom task will be automatically
deployed. You can right click the Toolbox in BIDS, click "Choose Items" and select
the task at "SSIS Control Flow Items". This article depicts the detailed information:
Building, Deploying, and Debugging Custom Objects
The above articles are for basic knowledge of how to create a SSIS custom task.
Sometimes there are some requirements which require your in-depth
understanding of SSIS development and .NET Windows Forms control
programming. Another commonly asked question for SSIS custom task is how
you can create a property for your custom task, but the property value need to
be selected from a dropdown list. The above examples do not show you how to
do this. If you do not know about Windows Forms control programming, this may
take a lot of time working on this. But if you know it, it will not be a difficult job.
Let us take the HelloWorldTask project for example. To implement this
requirement. You need to:
1. Create a custom type converter class inherited from an existing type
converter like StringConverter and override the existing functions. For
example:
class DateFormatConverter:StringConverter
{

176
public override bool
GetStandardValuesSupported(ITypeDescriptorContext context)
{
return true;
}
public override TypeConverter.StandardValuesCollection
GetStandardValues(ITypeDescriptorContext context)
{
return new StandardValuesCollection(new string[]
{ "yyyy-MM-dd","M/d/yyyy","d/M/yy"});
}
public override bool
GetStandardValuesExclusive(ITypeDescriptorContext context)
{
return false;
}
}
2. Define the attribute in the GeneralViewNode class as follows:
[TypeConverter(typeof(DateFormatConverter)),
DisplayName("Format"), Description("Display Date Format")]
public string Format
{
get
{
return format;
}
set
{
format = value;
}
}
3. Rebuild the project and deploy it. You may need to close your Visual Studio
and re-open it so as to use the latest version custom task.
You can read this great article for developing advanced functions for custom task
properties:

How do I improve package loading performance in BIDS
when I open a package which is imported from another
place?
Answer
This issue is usually caused by the fact that your SSIS package is complex with
many tasks including many connection managers. When you open the SSIS
package in BIDS, by default the validation process on each task will start. Since
your SSIS package is copied from another place, the connections may be invalid.
In this case, the validation process will spend a lot of time and cause the BIDS not
working during this time.
To resolve this issue, you can do as follows:
1. Before you add the SSIS package, select your SSIS project first, then click the
SSIS menu, and change your SSIS project to Offline mode by checking "Work
Offline".
2. Add your SSIS package to the project and change each Task's DelayValidation
property to True.
3. After these steps, you can modify the connections to be valid based on your
local test environment.

How do I use parameters in an SSIS ADO NET source?
Answer
You can use variables together with Expression to pass the parameters:
1. Switch to Control Flow, click the Data Flow Task.
2. In the Properties window, notice a property called Expression and a small
button next to it. Click the button to open the Expression Editor.
3. In the Property list, select [The name of ADO NET Source].[SqlComamnd]
and click the button under expression column to open Expression Builder.
4. Write the query with variable names and click the Evaluate Expression
button to test the expression. For example:
"SELECT * FROM EMPLOYEES WHERE FNAME='" + @[User::FName] + "'"
Note: The Integration Services expression syntax is similar to the syntax
that the C and C# languages use. Expressions include elements such as
identifiers (columns and variables), literals, operators, and functions. For
more information, you can refer to:

How do I refresh the layout information of a SQL Server
Integration Services (SSIS) package that is modified
programmatically?
Answer
The problem is due to the fact that when the package was first made in Business
Intelligence Development Studio (BIDS), the layout information was saved within
a xml tag called <packagevariable>, and all elements have their layouts written in
encoded xml in the xml file.
When you modify the package through .NET and add new elements, the layout
information is not updated. So when the package is loaded within the BIDS for
modification, the BIDS recognizes that some layout information is available, so it
will use this information to layout the ENTIRE PACKAGE. This causes the problem.
To solve the issue, you can remove the layout information programmatically,
then the package will layout the package in a default manner. The code below is
for your reference:
Application app = new Application();
string path = @"D:LibrariesDocumentsVisual Studio
2008ProjectsWCFSSISWCFSSISFEL.dtsx";
Microsoft.SqlServer.Dts.Runtime.Package pkg = app.LoadPackage(path,
null);
Executable exec = pkg.Executables["FLC"];
(exec as IDTSSequence).Executables.Add("STOCK:SEQUENCE");
string strXML = null;
pkg.SaveToXML(out strXML, null);
//Remove the layout information.
strXML = strXML.Remove(strXML.IndexOf("<DTS:PackageVariable>"),
strXML.IndexOf("</DTS:PackageVariable>") -
strXML.IndexOf("<DTS:PackageVariable>") + 22);
strXML = strXML.Remove(strXML.IndexOf("<DTS:PackageVariable>"),
strXML.IndexOf("</DTS:PackageVariable>") -
strXML.IndexOf("<DTS:PackageVariable>") + 22);
Package pkg2 = new Package();
pkg2.LoadFromXML(strXML, null);
app.SaveToXml(@"D:package.dtsx", pkg2, null);
