Thanks Dmitry.

I'm still new to IBO. You write

There is already a trigger defined in the database:

CENSUBNO_CENSUB_TRIG
Active BEFORE INSERT trigger for CENSUB at position 0

It seems the trigger isn't trigged :-) Do I need to define the fields in the TIBOTable object? In BDE you don't have to define the fields before using a TTable object.

Cheers
