Trigger is not firing immediately

От

Дата:
 
Hi All,
    I am having a trigger in table, If I update the the table manually trigger is firing immediately(say 200ms per row), But if I update the table through procedure the trigger is taking time to fire(say 7 to 10 seconds per row).
 
Please tell me what kind of changes can I make so that  trigger  fire immediately while updating the table through procedure ?
 
Regards,
Praveen

Show us more details like source-code of the procedure, the trigger and
a demonstration.

Sending the same email over and over again isn't going to get you a
response any quicker.

If you send the details of the trigger and the tables/fields it affects
then you might get a more helpful response.

 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;
 RETURN NULL;
 END; $BODY$
  LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION trigger1();

hello

Are you sure, so you don't call trigger recursion?
