Why does column alias not work in doctrine?

Question

My script is like this:

$query = Doctrine_Query::create ()
  ->select(\'count(p.product_id) as num_a\')              
  ->from ( \'ProductComments p\'

I also had a problem with setting alias. I had to set alias and then use "ORDER BY" with that alias. Following solution worked for me:

$myQuery->addSelect('() AS my_alias');
$myQuery->orderBy('my_alias');

In the result query looked like "...() AS p_0 ... ORDER BY p_0". I hope it will help someone.
