Hi guys,
I trying to return a 0.00 from a function it there are no records found else
return the amount.
create or replace function danmeans_getpayments(text)
returns numeric as
$BODY$
declare
invoice_num ALIAS FOR $1;
_paidamt numeric;
BEGIN
select sum(aropen_paid) into _paidamt FROM public.aropen where
aropen_applyto is not null and (aropen_applyto = $1) ;
IF (FOUND) THEN
RETURN _paidamt ;
END IF;
RETURN 0.00 ;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100
But all I get is either a blank or the amount paid. What am I doing wrong???
Johnf
