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"
