Re: simple query question: return latest

If 2 days are equal for color red, you still would get 2 rows returned.
Maybe the below is accurate.

SELECT g.color, g.date, g.entered_by
      FROM giventable g
   WHERE g.color     = 'red'
        AND g.date =
                  (SELECT MAX(g2.date)
                        FROM giventable g2
                     WHERE g2.color        = g.color
                  ) LIMIT 1
