title: Zend DB Framework examine query for an update
body: <p>So you can use something like this:</p>
  
  <pre><code>$query = $db-&gt;select();
  $query-&gt;from('pages', array('url'));
  echo $query-&gt;__toString();
  </code></pre>
  
  <p>to examine the sql that the Zend Db Framework is going to use for that SELECT query. Is there an equivilent way to view the SQL for an update?</p>
  
  <pre><code>$data = array(
     'content'      =&gt; stripslashes(htmlspecialchars_decode($content))
  );      
  $n = $db-&gt;update('pages', $data, "url = '".$content."'");
  ??
  </code></pre>
