Hi, thanks yes I was using AFTER, but it only works with BEFORE so finally I got it to work. thanks to all
Im just still wondering why here... *BEGIN IF NEW.time_type = 'Start' THEN SELECT t.time_index FROM table_ebscb_spa_log02 t WHERE t.fn_name = NEW.fn_name AND t.time_type = 'Start' ORDER BY t.timestamp02 DESC LIMIT 1 INTO t_ix; GET DIAGNOSTICS n = ROW_COUNT; IF (n = 0) THEN t_ix = 1; ELSE t_ix = t_ix + 1; END IF; END IF; NEW.time_index = t_ix; return NEW; END $$ LANGUAGE plpgsql;* I have to put return NEW, instead of NEW.time_index = t_ix???? Thanks to all again. -- View this message in context: http://postgresql.nabble.com/INSERT-a-number-in-a-column-based-on-other-columns-OLD-INSERTs-tp5854577p5854602.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
