We are having an issue on returning identity column using PB2017 R3 build 1858 connecting to MSSqlServer DB via ODBC

We have a table with insert trigger that insert into another table and we want the return identity value to be the id from the first table. Instead of @@Identity , we would like to use Scope_Identity() , but PB returns null with scope_identity()

A simple test is an insert into a table and a select @@identity(), scope_identity() in DB painter 

the select returns the id from the table inside the trigger and a null 

the same select returns valid ids in SqlServer management studio 

What is the suggested setting in PBODB170.ini for GetIdentity?

Hi Angela;

  Have you tried using the ReSelectRow() command after the insert DML to get the new Trigger set value?

Regards ... Chris

Hello Angela,

I believe this looks like a bug for PB Version (PB2017 R3 build 1858 connecting to MSSqlServer 2014 DB via ODBC) as i  faced the same problem while using scope_identity() to return the new id. The application just crashed out without any error message.

The same procedure works well for older version of PB. Lately i discontinued the procedure and opted the path as suggested by Chris. Luckily, i had used this logic only in one procedure and easily handled.

Regards.

Is there a driver setting you need to set?  OLE DB with native driver uses "identity='scope_identity()'
