Hello,
I have a small problem following statement executes well do not give me
proper results, rather subquery calleing another function is not executed at
all.
*perform sometable.pk, (select * from somefunction) from sometable where
somecondition;*
But* select * from somefunction;* and *perform * from somefunction*; and
also* select sometable.pk, (select * from somefunction) from sometable where
somecondition;* gets executed properly with all side effects.
Is there anything wrong in my first statement? OR perform can not used to
make join as in selects.
Thanks,
CPK
