Чтение данных без ORM-а
1.varresults = executeQuery(“some sqlselect text”);
2.while(!results.eof()){
3.results.first();
4.varaddress = results.fieldByName(“address”).asString();
5.varphone = results.fieldByName(“phone”).asString();
6.varemail = results.fieldByName(“phone”).asString();
7.vardateOfBirth= results.fieldByName(“birth”).asDate();
8.} 2

Использование ORM-а
1.varcustomers = Models.find(“select * from customers …”);
2.customers.forEach(function(aCustomer){
3.…
4.});
