Hi Jason, thanks for your reply.
I have setted the LockSQL property manually and the problem is solved for me.
In the TIBOQuery I have not found the property UseReturningClause.
For the sample code I will try to prepare as soon as possible, but they are at a particularly messed up so it will take me a few days, is that a problem?
Regards.

Maurizio
