Thinking about it, the EXCEPTION statement would be inside my user-
defined function (where I raise the exception in the first place), so
I cannot see how that would help. As far as I could understand, I
cannot call "ROLLBACK" (which is what I want to do) inside a user
defined function. I tried calling it and it was simply ignored. Or am
I missing something here?
