How to ORDER BY CASE in Doctrine2 (Symfony2)

Question

I want to run this query by using Doctrine in Symfony 2.3. But it seems like Doctrine does not understand CASE statement. Can anyone help? Thank you in advance!

This one does the job for me when ordering by a relation-table or a local column if no relation exists:

$doctrineQuery->add('orderBy', '(CASE WHEN COUNT(relation_table.uid)>0 THEN relation_table.price ELSE current_table.generic_price END) ASC');
