SELECT * FROM expo WHERE date = (SELECT max(date) FROM expo WHERE date < now()); In fact, you might want to rewrite the subselect. Oh, and "date" is likely to cause trouble as a column-name. SELECT * FROM expo WHERE my_date = ( SELECT my_date FROM expo WHERE my_date < now() ORDER BY my_date DESC LIMIT 1 ) -- Richard Huxton Archonet Ltd
