Subject Stored procedure return_value always null
Author flipmooooo
Hi,

Sorry for bothering u guys againbut i'm having some problems again
with my 'ever lasting' first SP. I have 2 SP's. In the main SP i call
the 2nd one. If in the 2nd SP a 'INVALID_ENTRY' exception occurs
EXCEPTION_DATA is filled with fieldinfo and passed back to the main
SP. But after returning to my main SP EXCEPTION_DATA is always NULL.
I tried putting 'EXIT' after 'EXCEPTION INVALID_ENTRY' but that
doesn't work either. Tried 'SUSPEND' too but since its a executable
procedure it shouldn't be used either according to the language
reference guide, exit should be used instead. Anyway 'SUSPEND' didn't
work either.

Greetings,
Filip Moons
