Symfony 小innerJoin查询

symfony 1.4和条令1.2中的旧查询

$user = Doctrine_Query::create()
                ->from('User.u')
                ->innerJoin('u.State s')
                ->where('u.id = ?', $id)
                ->andWhere('u.state_id = ?', $state_id)
                ->fetchOne();

现在，我在symfony2中的查询：

$repository = $this->getDoctrine()
->getRepository('FrontendAccountBundle:User');

$user = $repository->findBy(array(
    'activationId' => $activation_id), 
    array('state' => 3));

我的错误是：

无法识别的字段：状态

有什么问题

编辑：重新格式化的代码

更新

问题是用户实体中的变量是“state”而不是“stateId”。必须始终使用实体中的名称，而不是数据库中的名称。从用户到状态的连接也需要完成，因为stateId位于状态实体中

当需要连接时，最好使用queryBuilder或DQL

以下是一篇关于加入条令2 queryBuilder的帖子：

以下是Symfony教义书中的文档：

以下是我的项目中与您的问题非常相似的一个示例：

    $uid = 2;
    $rep = $this->getDoctrine()->getRepository('DevondevTrackRTimeBundle:Activity');
    $q = $rep->createQueryBuilder('a')
        ->select ('a.activityId, a.startTime, a.endTime, u.username')
        ->join('a.login','u')
        ->where('u.id = :uid')
        ->setParameter('uid', $uid)
        ->getQuery();

    $acts = $q->getResult();

如果我不需要用户表中的任何内容，查询可以写成

    $uid = 2;
    $rep = $this->getDoctrine()->getRepository('DevondevTrackRTimeBundle:Activity');
    $q = $rep->createQueryBuilder('a')
        ->where('a.login = :uid')
        ->setParameter('uid', $uid)
        ->getQuery();

    $acts = $q->getResult();

这是以相同方式重新处理的查询：

    $rep = $this->getDoctrine()->getRepository('FrontendAccountBundle:User');
    $q = $rep->createQueryBuilder('u')
        ->join('u.state','s')
        ->where ('u.id = :uid')
        ->andWhere ('s.stateId = :sid')
        ->setParameters(array('uid' => $id, 'sid' => $state_id))             
        ->getQuery(); 

    $user = $q->getSingleResult();

多亏了彼得让我有点兴奋

如果您不想再次使用symfony2（-docs）和doctrine2的愚蠢解决方案，因为您需要比symfony1.4多得多的代码，就像这样。试试我的解决办法

结果如下

        $em = $this->getDoctrine()->getEntityManager();
        $user = $em->createQuery('SELECT u FROM FrontendAccountBundle:User u
              INNER JOIN FrontendAccountBundle:State s
                WHERE
                u.activation_id=:activation_id
                and
                u.state=:state_id
                ')
            ->setParameter('activation_id', $activation_id)
            ->setParameter('state_id', 3)
            ->getSingleResult();

你能给我们看一下你的条令2的实体吗？你为什么不在条令2中使用查询生成器呢？当然可以。这里就是。对不起，不，如果我使用$user=$repository->findBy（数组（'activationId'=>$activation\u id），数组（'State'=>3））；或者用“国家”和小盘股。错误仍在出现。您还需要执行从用户到状态的连接。好的，您介意为这两个表发布一个非常简单的查询示例吗？我对doctrine2非常陌生，我真的很笨。它和你的doctrine1.2代码非常相似。我在回答中添加了一个指向另一个帖子的链接。抱歉，我不能在这里给出一个明确的代码示例，我在iPad上，没有代码编辑器或测试平台。重点是，我需要一个实体管理器和innerJoin的小示例。我从来不需要使用它。我已经用查询生成器更新了我的答案。是的，谢谢，这也很有效。但有一点是我需要doctrine2中比doctrine1.2中更多的代码。但那是另一个故事！再次感谢！
