Originally created by @danielspk on GitHub (Jul 18, 2017).

When requesting a partial object in a DQL query the discriminator column is returned.

$results = $em->createQuery("SELECT partial.{id, name} FROM Entity:ChildA")->getArrayResult();

The array results contains the keys: id, name and type - (type was not requested).

Entity configuration:

@InheritanceType("SINGLE_TABLE")
@DiscriminatorColumn(name="type", type="integer")
@DiscriminatorMap({
  "1" = "Entity\ChildA",
  "2" = "Entity\ChildB",
  "3" = "Entity\ChildC"
})

I didn't even know that array selection was possible with partial entity queries in DQL: nice catch!
