Assuming your New.dt is a date type and NEW.months is an integer, you probably want to change your expression to something like: NEW.dt + (NEW.months * INTERVAL '1 month') Also a good read: http://www.postgresql.org/docs/8.1/interactive/functions-datetime.html Jason Minion -----Original Message----- From: pgsql-admin-owner@postgresql.org [mailto:pgsql-admin-owner@postgresql.org] On Behalf Of Ramesh Patel Sent: Tuesday, February 28, 2006 1:37 AM To: pgsql-admin@postgresql.org Subject: [ADMIN] Problem in date function dear All I am use Trigger in my database .
