rowid in trigger?

Hi All, Maybe I missed something in the manuals... Is there are way to reference rowid in a create trigger statement? A messy work around is to use: (select rowid from tablex where fieldx = pre.fieldx_value) I get an error if I use: pre.rowid or just rowid Thanks in advance Phuoc Ho Example: create trigger nps_users_updupdate on nps_users referencing old as pre new as post for each row (execute procedure add_trigger(user,current, (select rowid from nps_users where users_code = pre.users_code)));
