Hi, When adding sets of new child tables to a artitioned table, I need to update the triggers with new dates added as new condition. See sample below. My question is, what will happen if the update to the trigger happen at the same time as insert operation to the master table? CREATE OR REPLACE FUNCTION t_agg_billing() RETURNS "trigger" AS $BODY$ DECLARE BEGIN IF (TG_OP = 'INSERT') THEN IF NEW.CallDate = 20071001 THEN INSERT INTO z_agg_billing_d_20071001 VALUES ( NEW.* ); ELSEIF NEW.CallDate = 20071002 THEN INSERT INTO z_agg_billing_d_20071002 VALUES ( NEW.* ); ELSEIF NEW.CallDate = 20071003 THEN INSERT INTO z_agg_billing_d_20071003 VALUES ( NEW.* ); ... ... ... END IF; END IF; RETURN NULL; END; $BODY$ LANGUAGE 'plpgsql' VOLATILE; ALTER FUNCTION t_agg_billing() OWNER TO sa; ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org/
