Thanks for that Ian, worked a treat. However, can someone tell me why
select n.ntimestamp, n.nmid from news n where n.ntimestamp > current_time -
interval '5 minutes';
works while
select n.ntimestamp, n.nmid, m.mfname, m.mlname from news n, members m order by ntimestamp desc limit 1 where (n.nmid
=m.mid) and (n.ntimestamp > current_time - interval '5 minutes');
has a parse error at or near "where"
