如何使用symfony2和doctrine从数据库中手动查询

Question

我正试图在我的用户存储库中查询数据库(symfony2):

namespace Doobin\UserBundle\Entity;

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
public function pageAccess($User=1,$Page='_home')
{
    $query="SELECT `user` FROM `vu001_user_permission` WHERE `user` = '$User' AND `path`='$Page'";
    $conn = Doctrine_Manager::getInstance()->connection();
    $stmt = $conn->prepare($query);
    $stmt->execute();
    return $stmt;
}

但它不会起作用.它在现场直播时停止工作 $conn = Doctrine_Manager::getInstance()->connection();

我从symfony网站tuturial复制了那个.

我也试过这个:

$em = $this->getDoctrine()->getEntityManager();
    $connection = $em->getConnection();
    $statement = $connection->prepare("SELECT `user` FROM `vu001_user_permission` WHERE `user` = '$User' AND `path`='$Page'");
    $statement->execute();
    $results = $statement->fetchAll();

当它到达生产线时停止工作 $em = $this->getDoctrine()->getEntityManager();

并试过这个:

namespace Doobin\UserBundle\Entity;

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
public function pageAccess($User=1,$Page='_home')
{
return $this->getEntityManager()
        ->createQuery(
            'SELECT p FROM UserBundle:User p ORDER BY p.name ASC'
        )
        ->getResult();
}
}

$this->getEntityManager()现在正在工作,请帮忙我很开心.我查了一切.

我错过了什么吗？

执行以下操作以获取连接:

$em = $this->getDoctrine()->getEntityManager();
$conn = $em->getConnection();

要查询,

$stmt = $conn->prepare($query);
$stmt->execute();
$results = $stmt->fetchAll();
