这段代码中的错误
我想用多连接创建查询，但不幸的是显示了这个错误
[这是我的SearchController控制器]
class SearchController extends Controller {
public function indexAction() {
$em = $this->get('doctrine.orm.entity_manager');
$users = $em
->createQueryBuilder('P')
->select('P.pname, Q.qname,P.gender,P.phone,P.yearsOfExperience,P.graduationYear,c.cname')
->add('from', 'serachBundle:Person P')
->Join('P.Qualification', 'Q')
->Join('Q.Category', 'c')
->where('P.qualificationId=Q.id')
->andwhere('Q.categoryId=c.id')
->getQuery();
$user = $users->getResult();
print_r($user);
//qualification
$Qlist = $this->getDoctrine()
->getRepository('serachBundle:qualification')
->findAll();
//category
$Catlist = $this->getDoctrine()
->getRepository('serachBundle:category')
->findAll();
return $this->render('serachBundle:Default:Search.html.twig', array('user' => $user, 'Qlist' => $Qlist, 'Catlist' => $Catlist));
}

如果有人能解决这个问题，请提前致谢。这将是一个非常好的帮助
答案 0 :(得分：0)
您将关系命名为$ qualificationid，因此您应该使您的查询如下：
->Join('P.qualificationid', 'Q')
->Join('Q.categoryid', 'c')
请记住在存储库类中进行所有查询。并且请尝试将您的捆绑包从serach重命名为搜索:-D
