Re: [PERFORM] Trigger is not firing immediately

Hi all,
Please find the procedure and trigger which took more time when we try
to update value in table through Procedure.

CREATE OR REPLACE FUNCTION procname1(args)
RETURNS void AS
$BODY$
DECLARE
{
---
Some code blocks
---
}
BEGIN

--> to here it is executing fastly after reaches this statement it's
taking time

update table1 set col1 = val1 where pk = val2 and col2 = val3;

-----> HERE table1 IS HAVING THE TRIGGER I GIVEN BELOW THE TRIGGER(
trigger1)

exception
WHEN OTHERS
THEN
raise notice '''EXCEPTION IN procname1 BLOCK 3 : %''',SQLERRM;
NULL;
END; $BODY$
LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION procname1(args);

CREATE OR REPLACE FUNCTION trigger1()
RETURNS "trigger" AS
$BODY$
BEGIN

IF (TG_OP='UPDATE') THEN
IF( some condition )
THEN
BEGIN
INSERT INTO table2(cols)
VALUES(values);
IF NOT FOUND THEN
NULL;
END IF;
EXCEPTION
WHEN OTHERS
THEN
NULL;
END;
END IF;
END IF;
