title: Doctrine Update by DQL + field with parenthesis: "(" and ")"
body: <p>I have a doctrine update query to save my data:</p>
  <blockquote>
  <p>$customer = Doctrine_Query::create()</p>
  <p>-&gt;update('Customer')</p>
  <p>-&gt;set('fax',&quot;'&quot;. $this-&gt;getRequest()-&gt;getParam('fax').&quot;'&quot;)</p>
  <p>-&gt;where('id ='.$this-&gt;getRequest()-&gt;getParam('id'))</p>
  <p>-&gt;execute();</p>
  </blockquote>
  <p>The problem is that the field fax has parenthesis and doctrine returns an error in the query because of these parenthesis &quot;(&quot; and &quot;)&quot;.</p>
  <p>Somebody knows a solution for this?
  Thank's</p>
