Hello,

The question becomes how do you update the "item id" on the "groups"
table when you add new records to "items".
I have a trigger on items table:
CREATE TRIGGER items_insert
BEFORE INSERT
ON items
FOR EACH ROW
EXECUTE PROCEDURE items_oninsert();
CREATE OR REPLACE FUNCTION items_oninsert()
RETURNS trigger AS
$BODY$
BEGIN
UPDATE groups SET last_item = NEW.id WHERE id=NEW.group AND
(last_item IS NULL OR last_item<NEW.id);
RETURN NEW;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
Thanks!
