title: How to load point data into zend_db_row classes?
body: <p>I have following classes</p>
  
  <ul>
  <li><code>My_Table extends Zend_Db_Table_Abstract</code></li>
  <li><code>My_Row extends Zend_Db_Table_Row_Abstract</code></li>
  </ul>
  
  <p>I my table has a column of the type <code>Point</code></p>
  
  <pre><code>var_dump($row-&gt;point);
  string(25) "=
  ףp@@=
  ףp�^@"
  </code></pre>
  
  <p>How can I fetch the  <code>point</code> column as text ("32.23,122.21") through these classes? The select should probably have</p>
  
  <pre><code>CONCAT( X( `point` ) , ',', Y( `point` ) ) AS point
  </code></pre>
  
  <p>But I don't know what methods or properties to override. I've already tried manually setting $_cols in <code>My_Table</code> to no avail.</p>
