php - 错误:预期的 Doctrine\ORM\Query\Lexer::T_WITH，得到 'ON'

Question

我编写了以下代码用于从数据库中获取数据:

function getnotificationAction()
{
    $session = $this->getRequest()->getSession();
    $userId = $session->get('userid');

    $entitymanager = $this->getDoctrine()->getEntityManager();
    $notification = $entitymanager->getRepository('IGCNotificationBundle:Notifications');
    $userNotification = $entitymanager->getRepository('IGCNotificationBundle:Usernotifications');
    $query = $entitymanager
                 ->createQuery("SELECT n.notificationid, n.title,n.notificationmessage, u.creationdate, u.notificationid, u.messagestatus From IGCNotificationBundle:Notifications AS n JOIN IGCNotificationBundle:Usernotifications AS u ON u.notificationid = n.notificationid WHERE u.userId = :userId ORDER BY n.creationdate DESC")->setParameter('userId', userId);

    $notifications = $query->getResult();

    return $this->render('IGCNotificationBundle:Default:notification.html.twig', array('notifications' => $notifications));
} }

但它正在给予:

[Syntax Error] line 0, col 203: Error: Expected Doctrine\ORM\Query\Lexer::T_WITH, got 'ON' 500 Internal Server Error - QueryException 1 linked Exception: QueryException »

我认为您应该将关键字“ON”替换为“WITH”。

文档摘录:

Joins between arbitrary entities are now possible in DQL by using the syntax FROM Foo f JOIN Bar b WITH f.id = b.id.
