title: Fetch values of aggregated columns in Propel
body: <p>I am trying to make following query in Propel:</p>
  
  <pre><code>$criteria = new Criteria();
  $criteria-&gt;clearSelectColumns();
  $criteria-&gt;addSelectColumn(TableName::COLUMN1)
      -&gt;addSelectColumn(TableName::COLUMN2)
      -&gt;addAsColumn('alias1', 'DATE('.TableName::INIT_TIME.')')
      -&gt;addAsColumn('alias2', 'COUNT('.TableName::DOWNLOAD_START_TIME.')')
      -&gt;addGroupByColumn('DATE('.TableName::INIT_TIME.')')
      -&gt;addGroupByColumn(TableName::DOWNLOAD_START_TIME);
  
  $logs = TableName::doSelect($criteria);
  </code></pre>
  
  <p>It seems that everything OK and according to MySQL log file query generated and saved to server right. However I cannot get values of aggregated columns.</p>
  
  <p>doSelect returns array of TableName objects which have no methods to fetch aggregated columns. So, how can I do it?</p>
  
  <p>PS: I am talking about symfony 1.4 with Propel if it matters.</p>
