mapping - 如何使用 Doctrine 2 管理 VIEW？

Question

我想用 映射一个 sql-view Doctrine2 .

此 View 是 临时表 包含一些统计信息，无需重写生成 View 的 sql 即可显示

我尝试像表一样映射，但更新架构删除 View 并创建表

我也尝试使用 NativeSQL ...

public function getMessages(\Project\Bundle\MyBundle\Entity\User $user) {
    $rsm = new \Doctrine\ORM\Query\ResultSetMapping();
    $rsm->addEntityResult('MessageCenter', 'v');
    $rsm->addFieldResult('v', 'user_id', 'user_id');
    $rsm->addFieldResult('v', 'tot', 'tot');
    $rsm->addFieldResult('v', 'read', 'read');
    $rsm->addFieldResult('v', 'to_read', 'to_read');
    $rsm->addFieldResult('v', 'stored', 'stored');
    $rsm->addFieldResult('v', 'spam', 'spam');

    $q = "SELECT * FROM message_stats_view WHERE user_id = ?";
    $rsm = new \Doctrine\ORM\Query\ResultSetMapping;
    $query = $this->getEntityManager()->createNativeQuery($q, $rsm);
    $query->setParameter(1, $user->getId());
    echo $query->getSQL();
    var_dump($query->execute());
    exit;
}

我使用 getter 和 setter 创建实体 MessageCenter，但我的输出是:

SELECT * FROM message_stats_view WHERE user_id = ?
array
  empty

(由 OP 在 aq 问题编辑中回答。转录到社区维基答案。见 Question with no answers, but issue solved in the comments (or extended in chat))

OP写道:

I SOLVED!!!!

public function getCentroMessaggi(\Project\Bundle\MyBundle\Entity\User $user) {
    $connection = $this->getEntityManager()->getConnection();
    $q = "SELECT * FROM message_stats_view WHERE user_id = :id";
    $stmt = $connection->executeQuery($q, array('id' => $user->getId()));
    return $stmt->fetch();
}

This return an array. PERFECT!
