roger-
you need an exception block as in...
CREATE OR REPLACE FUNCTION sp_a_005("login" "varchar", pwd "varchar")
RETURNS boolean AS
$BODY$
BEGIN
UPDATE...
EXCEPTION
WHEN NO_DATA_FOUND
RETURN FALSE
WHEN PROGRAM_ERROR
RETURN FALSE
WHEN OTHERS
RETURN FALSE
RETURN TRUE
END;

Subject: [GENERAL] get value after updating table
Hi,
I wrote a function which should update a table field.
However, i would like somehow to control that update was done.
for that i was thinking to return a boolean : true is update was done, false
if an error happened.
however, i can i do that ? I mean how can i know if UPDATE has been correctly
executed ?
here is my function :
CREATE OR REPLACE FUNCTION sp_a_005("login" "varchar", pwd "varchar")
RETURNS boolean AS
$BODY$
DECLARE
BEGIN
UPDATE accounts
SET account_pwd = $2
WHERE account_login = $1;
RETURN;
END;
