Hi Joshua
Thanks for the mail.
I'm looking for something like your function and trigger on your page
here:
-- DROP FUNCTION UsersUpd();
CREATE FUNCTION UsersUpd() RETURNS OPAQUE AS '
BEGIN
UPDATE AuthNames SET Name = NEW.Name WHERE Name = OLD.Name;
NEW.Created = OLD.Created;
NEW.Modified = current_timestamp;
NEW.AuditSeq = nextval(''AuditSeq'');
RETURN NEW;
END;
' LANGUAGE 'plpgsql' WITH (isstrict);
-- SELECT DropTrigger('Users','UsersUpd');
CREATE TRIGGER UsersUpd BEFORE UPDATE ON Users
FOR EACH ROW EXECUTE PROCEDURE UsersUpd();
However my version of getting current_timestamp creates an error:
update ideas set title = 'three' where title ~ 'one';
NOTICE: Error occurred while executing PL/pgSQL function
update_date_time
NOTICE: line 3 at assignment
ERROR: Bad time external representation '16:11:45.820720+01'
Any ideas on why this may be?
Thanks for your help
Rory
