<mailto:andreas@visena.com>>: Hi all. I have this simple schema: create
table fisk(
name varchar primary key,
autofisk varchar
); I want to update the column "autofisk" on commit based the value of
"name", so I created this trigger: CREATE OR REPLACE FUNCTION fisk_tf()
returns TRIGGER AS $$
BEGIN
raise notice 'name %', NEW.name <http://NEW.name;;
NEW.autofisk = NEW.name <http://NEW.name; || CURRENT_TIMESTAMP::text;
RETURN NEW;
END;
$$ LANGUAGE plpgsql; CREATE CONSTRAINT TRIGGER fisk_t AFTER INSERT OR
UPDATE ON fisk DEFERRABLE INITIALLY DEFERRED It should be BEFORE INSERT OR
UPDATE trigger He he, yes - I know that will work, but I need the trigger to
be run as a constraint-trigger, on commit, after all the data is populated in
other tables and this table. -- Andreas Joseph Krogh CTO / Partner - Visena AS
