Using this function on a MS SQL Server 2000 database connection with the syntax:
$res = odbc_columns($connId, $dbName, "%", $tableName, "%");
I actually get a result set with THESE columns name:
TABLE_CAT, TABLE_SCHEM, TABLE_NAME, COLUMN_NAME, DATA_TYPE, TYPE_NAME, COLUMN_SIZE, BUFFER_LENGTH, DECIMAL_DIGITS, NUM_PREC_RADIX, NULLABLE, REMARKS
in the order displayed.
