title: Doctrine check fetchOne
body: <p>My simple query:</p>
  
  <pre><code>    $list = Doctrine_Query::create()
              -&gt;from('liste l')
              -&gt;where('l.id =?', $id)
              -&gt;fetchOne();
  </code></pre>
  
  <p>$id = 123;</p>
  
  <p>I know that there is no entry with the $id =123 in my database. When I count $list, I get the result 1. How do I know with my query or the result of my query that there is no entry with the $id = 123 in my database?</p>
