title: Won't group by?
body: <p>I am facing a really wierd issue, that i cannot GROUP by. If i do, it won't show the "best time". It's kinda wierd.</p>
  
  <p>Here is the SQL String which works (But it shows the same quiz 4 times, which it shouldn't!)</p>
  
  <pre><code>SELECT distinct a.quiz_id, a.time, b.end, b.images, b.prize_title 
  FROM entries a, quiz b 
  WHERE a.quiz_id = b.id AND a.member = '".$_SESSION['id']."' 
  ORDER BY a.time ASC
  </code></pre>
  
  <p>Screen of output: <a href="http://imgur.com/mOfBK3q" rel="nofollow">http://imgur.com/mOfBK3q</a></p>
  
  <p>This show NOT the best time (Fastest time => ASC)</p>
  
  <pre><code>SELECT distinct a.quiz_id, a.time, b.end, b.images, b.prize_title 
  FROM entries a, quiz b 
  WHERE a.quiz_id = b.id AND a.member = '".$_SESSION['id']."' 
  GROUP BY a.quiz_id 
  ORDER BY a.time ASC
  </code></pre>

  <p>The column "a.time" is miliseconds and the column is DOUBLE.</p>
