I have entity like this:
/**
*
* @Table(name="table")
* @Entity
*/
class Table {
/**
* @Column(type="integer")
* @Id
* @GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @ManyToOne(targetEntity="Entities\Users")
* @joinColumn(name="userId", referencedColumnName="id")
*/
private $User;
/**
* @Column(type="string")
*/
private $text;
}
If i do $q->getQuery()->getSingleResult()->getUser()->getUserId()
doctrine generate query like:
SELECT * FROM table t INNER JOIN users u ON u.id = t.userId WHERE id = 100
but if i don`t need table users, how to get an userId.
In pure SQL i can just
SELECT * FROM table WHERE id = 100
and get userId without join users table.
You may also want to look at the IDENTITY() function (Doctrine version >2.2).
Example:
SELECT IDENTITY(t.User) AS user_id from Table
Should return:
[ ['user_id' => 1], ['user_id' => 2], ... ]
Try this:
$q = $qb->getQuery();
$q->setHint(\Doctrine\ORM\Query::HINT_INCLUDE_META_COLUMNS, true);
According to the documentation, D2 entities should never need the foreign key exposed as it is all done internally by the mapping information, however, as you have found out, there is a need now and then to have this value. To do this, simply supply the mapping info for the foreign key.
I don't know doctrine2 but from what I read this is a ORM. So I would suggest that you need a form of lazy loading where user isn't loaded. This article suggests that lazy loading is available in doctrine2 .
This may result in multiple db calls if user is later used on the returned table. You have to weigh this up with the idea of grabbing the data in one hit.
