Doctrine 的 DQL 未正确生成查询

Question

我有一个实体类：

/**
 * @ORMEntity
 * @ORMTable(name="""app_auth"".""User""", schema="app_auth")
 */
class User {
    /**
     * @ORMColumn(type="string")
     * @ORMId
     * @ORMGeneratedValue(strategy="NONE")
     */
    private $username;
    /**
     * @ORMColumn(type="string", nullable=true)
     */
    private $email;
    /**
     * @ORMColumn(type="string", nullable=true)
     */
    private $password;
    // removed setters and getters
}

它与数据库完美结合。实际上，此控制器按预期工作：

/**
 * @Route("users/{username}",
 *     defaults={
 *      "_format" = "json"
 *     })
 * @Method("GET")
 */
public function getUserAction($username)
{ 
    $user = $this->getDoctrine()
        ->getRepository('BelkaTestBundle:User')
        ->find($username);
    if(!$user)
        throw $this->createNotFoundException("User $username not found");
    $res = new JsonResponse();
    $res->setData(array(
        'user' => $user->getUsername(),
        'email' => $user->getEmail()));
    return $res;
}

但是，如果我尝试通过 DQL 进行查询，如下所示：

/**
 * @Route("users/{username}",
 *     defaults={
 *      "_format" = "json",
 *     })
 * @Method("GET")
 */
public function getUserAction($username)
{
    $repository = $this->getDoctrine()
            ->getRepository('BelkaTestBundle:User');
    $query = $repository->createQueryBuilder('u');
    $users = $query->getResult();
    /*something here to manage and return the results*/
    return $res;
}

我得到的是一个Symfony错误：

An exception occurred while executing 'SELECT "0_.username AS username0, "0_.email AS email1, "0_.password AS password2 FROM "app_auth"."User" "0_':
SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near "0"
LINE 1: SELECT "0_.username AS username0, "0_.email AS email1, "0_.p...

通过var_dumping $query->getResult()命令，我得到的是以下查询，引用起来看起来很糟糕：

SELECT "0_.username AS username0, "0_.email AS email1, "0_.password AS password2 FROM "app_auth"."User" "0_

请注意，我使用的是实体的架构名称。我无法弄清楚我的 DQL 出了什么问题。有什么帮助吗？我正在使用 Symfony 2.8 LTS

仅引用表名，将架构名称保留为不引号：

* @ORMTable(name="app_auth.""User""", schema="app_auth")
