Apparently, this is a known (to you) limitation of DSQL. As
PHP/Firebird is based on DSQL, there is no way to circumvent
limitations it imposes.

However, ibase_query()'s return value *is* based on the result of the
procedure in case of an 'EXECUTE PROCEDURE ...' statement, so you
might want to check what goes on there.
