Thank you Jie for your help. I am bit confused about how it works. I want for
each row , obtained by select statment, get certain values and then do some
calculations and out put that resulst eg
for rec IN select title, dcount from songs where artist='xyz'
tcount:= tcount+rec.dcount;
END LOOP;
return tcount;
would this work ?
Thanks again for your help.
