Your union creates a table called rss_feed. This table has 4 columns (page_title, last_update, article and reference) from which you try to select the unknown column 'title'. So basicly, exactly what your db is telling you. If it doesn't make sense, strip the outer select and see what your subquery returns. That should make it more clear. regards On Sat, 2010-04-24 at 20:50 -0400, Ron Piggott wrote: > I am received the error message: > > Unknown column 'title' in 'field list' > > from the query below.
