title: Zend Db Table and setting fetch mode
body: <p>I would like to change the fetch mode within an extended class of Zend_Db_Table_Abstract. The following does <strong>not</strong> work:</p>
  
  <pre class="lang-php prettyprint-override"><code>&lt;?php
  class Foo extends Zend_Db_Table_Abstract
  {·
    function bar()
     {
       return $this-&gt;fetchAll(Zend_Db::FETCH_NUM);
     }
  }
  </code></pre>
  
  <p>Anybody have an idea how to do it properly??
  Thanks!</p>
