php - Doctrine 2 - How to use discriminator column in where clause

Question

I was used discriminator column in where clause like this:

//f = root entity
$qb = $this->createQueryBuilder('f');
$qb->add('where', 'f.format = 'image' OR f.format = 'text'');

I've got an error: "Message: [Semantical Error] line 0, col 73 near 'format = 'image'': Error: Class EntitiesFileAbstractFile has no field or association named format"

How can i use discriminator column in where clause?

Thanks.
