我以各种方式搜索论坛，并尝试了我能找到的每一个解决方案。不幸的是没有用。我需要在教义中使用leftJoin而不能管理。在php我的管理员一切正常。
sbt compile
我尝试使用注释assotiations和每个可能的queryBuilder变体。每次我都有不同的错误。
我的实体（我省略了吸气剂和制定者）：
的appbundle \实体\ JobOffer

我找到了问题的答案。
的appbundle \实体\ JobOfferRepository
<?php
namespace AppBundle\Entity;
/**
* JobOfferRepository
*
* This class was generated by the Doctrine ORM. Add your own custom
* repository methods below.
*/
class JobOfferRepository extends \Doctrine\ORM\EntityRepository
{
public function getPaginateOffersbyRegion($currentPage = 1, $quantity = 5, $regId)
{
$firstResult = ($currentPage * $quantity) - $quantity;
return $this->createQueryBuilder('p')
->select('p')
->leftJoin('AppBundle:LocationToJobOffer', 'u', 'WITH', 'u.offerId = p.offerId')
->addSelect('u.cityName')
->where('u.regionId = :regId')
->setParameter('regId', $regId)
->addOrderBy('p.offerId', 'DESC')
->setFirstResult($firstResult)
->setMaxResults($quantity)
->getQuery()
->getArrayResult();
}
}
现在一切正常。

首先，您必须创建association mapping。
示例：
...
class LocationToJobOffer
{
/**
* @ORM\ManyToOne(targetEntity="JobOffer")
* @ORM\JoinColumn(name="offer_id", referencedColumnName="id")
*/
private $jobOffers;
...
class JobOffer
{
/**
* @OneToMany(targetEntity="LocationToJobOffer", mappedBy="jobOffers")
*/
private $locationToJobOffer;
...
之后，您的查询将如下所示：
$query = $this->createQueryBuilder('LocationToJobOffer')
->select('LocationToJobOffer', 'JobOffers')
->leftJoint('LocationToJobOffer.jobOffers', 'JobOffers')
->where('LocationToJobOffer.regionId = 9')
->getQuery();
