Question

So I have 3 entities within one table. I need to be able to search 2 out of the 3 entities in one select statement, but I’m not sure how to do this.

Answer 1

Use the INSTANCE OF operator in your dql query like this (where User is your base class):

$em->createQuery('
    SELECT u 
    FROM Entity\User u 
    WHERE (u INSTANCE OF Entity\Manager OR u INSTANCE OF Entity\Customer)
');

Doctrine translates this in the sql query in a WHERE user.type = '...' condition.

See here for more details on the dql query syntax.
