[DDC-1256] Generated SQL error with DQL WITH and JOINED inheritance

Duplicate — Wed, 1 May 2013 18:46:53 +0000

I've created an entity that has a one to one relationship to a class in an inheritance tree and I'm using class table inheritance in Doctrine. When I try to add a DQL WITH statement on a column in the super class to the join, the generated SQL incorrectly places the statement in the child classes JOIN ON section.

Here's the DQL:

SELECT p FROM Fampus_Entity_Photo p LEFT JOIN p.flag f WITH f.status='ok'

Here's the generated SQL:

SELECT p0_.id AS id0, p0_.name AS name1, p0_.path AS path2, p0_.type AS type3, p0_.reference_id AS reference_id4, p0_.view_count AS view_count5, p0_.created AS created6, p0_.modified AS modified7, p0_.event_id AS event_id8, p0_.user_id AS user_id9, p0_.school_id AS school_id10, p0_.flag_id AS flag_id11 FROM photos p0_ LEFT JOIN flaggedcontent_photo f1_ ON p0_.flag_id = f1_.id AND (f2_.status = 'ok') LEFT JOIN flaggedcontent f2_ ON f1_.id = f2_.id

Note that f2_.status = 'ok' is the correct statement, but it is in the wrong LEFT JOIN ON section.

Here are my entities (significantly clipped):

/**
 * @Table(name="photos")
*/
class Photo {
    /**
     * @OneToOne(targetEntity="FlaggedContent_Photo", mappedBy="photo")
     * @JoinColumn(nullable=true)
     */
    protected $flag;
}

/**
 * @DiscriminatorColumn(name="type")
 * @DiscriminatorMap({
 *     "photo" = "FlaggedContent_Photo"
 * })
 * @InheritanceType("JOINED")
 * @Table(name="flaggedcontent")
*/
abstract class FlaggedContent {
    /**
     * Database identifier
     *
     * @Id
     * @Column(type="integer")
     * @GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * Status
     *
     * @Column(type="text")
     * @var string
     */
    protected $status;
}

/**
 * @Entity
 * @Table(name="flaggedcontent_photo")
 */
class FlaggedContent_Photo extends FlaggedContent {
    /**
     * @OneToOne(targetEntity="Photo", inversedBy="flag")
     */
    protected $photo;
}
