e.g.
Try:
CREATE TABLE emp ( id int4 primary key, empname text, salary int4, last_date datetime, last_user name);
CREATE FUNCTION emp_stamp () RETURNS OPAQUE AS BEGINupdate emp set last_date=''now''::timestamp where id=NEW.id;
RETURN NEW; END;
' LANGUAGE 'plpgsql';
CREATE TRIGGER emp_stamp BEFORE UPDATE ON emp FOR EACH ROW EXECUTE PROCEDURE emp_stamp();
