title: DISTINCT fields NOT to show up in cakephp 1.3
body: <p>I'm running the feeds Table where I don't want DISTINCT fields with "NULL" to retrieve. </p>
  
  <pre><code>$this-&gt;Feed-&gt;recursive = 0;
  $this-&gt;paginate = array('Feed' =&gt; array(
  'limit' =&gt; 6, 
  'fields' =&gt; 'DISTINCT Feed.* IS NOT NULL',
  'conditions' =&gt; array('Feed.member_id' =&gt; $friends_ids), 
  'order' =&gt; array('Feed.created' =&gt; 'DESC'), 
  ));
  $notes = $this-&gt;paginate('Feed');
  $this-&gt;set('notes', $notes);
  
  // debug($notes);
  unset($notes);
  </code></pre>
  
  <p>This gives me an error. Warning (512): SQL Error: 1054: Unknown column 'Feed.* IS NOT NULL'. Running this on cakephp 1.3 Thanks.</p>
