How to write a DQL select statement to search some, but not all the entities in a single table inheritance table

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

The answer for multiple instances actually doesn't work. You would have to do something like this to check for multiple instances.

$classes = ['Entity\Manager', 'Entity\Customer'];
$qb = $this->createQueryBuilder('u');
->where('u.id > 10') //an arbitrary condition, to show it can be combined with multiple instances tests
->andWhere("u INSTANCE OF ('" . implode("','", $classes) . "')");
