I have an entity Entity\User with avatar:

/**
 * @ORM\OneToOne(targetEntity="Entity\Avatar", cascade={"remove"}, fetch="LAZY")
 */
protected $avatar;

And Entity\Message entity

/**
 * @ORM\ManyToOne(targetEntity="Entity\User")
 */
protected $user;

When i try to load all messages with users and avatars. But not all user have avatar.

    SELECT m, u, a
    FROM Entity\Message m
    JOIN m.user u
    JOIN u.avatar a
    ORDER BY m.id DESC

How to load all messages with user who avatars and who does not have?
