Thomas,

Yes, it would. That's why I petitioned to have them add an implicit SUSPEND
when none are included and there are columns for output.
See: http://tracker.firebirdsql.org/browse/CORE-3695

With FB 2.5 you would only be able to use them with any connectivity library
if you modify it to have a call to SUSPEND in the body.
See: http://tracker.firebirdsql.org/browse/CORE-3680

Look closely at the dialog between Adriano and Vlad.

Vlad answered:
"IIRC, initial implementation was changed at v2.5 to be more consistent with
more strict rules of usage of SUSPEND in PSQL"

There appears to have been a deliberate departure from the legacy ability to
omit the SUSPEND and yet get a singleton output result.

Hope this helps clear up the murky waters.

Perhaps you will consider pushing for the implementation of my request so
that legacy applications will not be broken. I see nothing gained by forcing
people to plunk in a SUSPEND in all their singleton execute block and stored
procedure statements.

Thanks,
Jason

Hello Jason,

Wouldn't that break a LOT OF legacy applications in respect to the usage
of executable SPs, as we have been told over the last 10 years not to
use SUSPEND in executable SPs. ;-)

Back to IBO: How would you use executable SPs in Firebird 2.5 with IBO?


Thanks,
Thomas
