Assume I've an entity, which references itself to map parent-child-relations
class Food{ /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ protected $id; /** * @ORM\ManyToOne(targetEntity="Food", inversedBy="foodChildren") * @ORM\JoinColumn(name="food_group_id", nullable=true) */ protected $foodGroup; /** * @ORM\OneToMany(targetEntity="Food", mappedBy="foodGroup", fetch="LAZY", cascade={"remove"}) */ protected $foodChildren;I have a use case where I want to get food_group_id of an entity without getting full parent object from database. Using fetch="LAZY" doesn't keep Doctrine from querying again. Is there a way to return only the ID when getting $food->getFoodGroup()?
