title: Increment a column in MySQL
body: <p>Is there a way in Zend to increment an integer, held in a MySQL column, by 1?</p>
  
  <p>Thanks</p>
  
  <p>edit:</p>
  
  <p>My current code is like:</p>
  
  <pre><code>$row = $this-&gt;find($imageId)-&gt;current();
  $row-&gt;votes = // THIS IS WHERE I WANT TO SAY INCREMENT
  $row-&gt;save();
  </code></pre>
