It would be better if you could provide the source of that trigger and involved

hello,

I'm trying to update a columm on a table with a trigger
but it don't work on PostgreSQL 7.2 (i686-pc-linux-gnu, compiled by GCC
2.96).

when I update a row the trigger does nothing.
what can I do?

thanks in advance

tony


here is my trigger:

########################################################
CREATE FUNCTION update_my_objekt() RETURNS OPAQUE AS '
BEGIN
        RAISE NOTICE ''My Trigger is updating the table'';
        IF OLD.status=''Activo'' THEN
                NEW.tempo := 10;
                NEW.actual := now();
        END IF;
        RETURN NEW;
END;
' LANGUAGE 'plpgsql';


CREATE TRIGGER update_online BEFORE  UPDATE ON iobjects
    FOR EACH ROW EXECUTE PROCEDURE update_my_objekt();

##########################################################
