Sorry if I didn't make myself plain enough, but I had

create view loco_dets as
select * from locos l -- includes lid which I want
left outer join
(select lnid, lnumber.......) ln on ln.lnid = l.lid
.......

The problem is that I have to have lnid in the sub-select to allow the 'on'
clause to work, but I don't want lnid to appear in the resulting view.
