symfony3，doctrine，leftJoin

-1

我以各種方式搜索論壇，並嘗試了我能找到的每個解決方案。不幸的是沒有工作我需要在教條中使用左連接並且不能操縱。在PHP我的管理員一切正常。symfony3，doctrine，leftJoin

SELECT a.`offer_id`, b.* FROM `location_to_job_offer` a LEFT JOIN `job_offer` b ON a.`offer_id` = b.`offer_id` WHERE `region_id` = 9

我試着使用註釋分配和每個可能的queryBuilder變體。每當我得到不同的錯誤。

我的實體（我中省略getter和setter）：

你能指出我在正確的請帶這個方向嗎？非常感謝提前。

讓我看看你的存儲庫類文件。我確定你在庫類中有語法問題。 –

首先，您必須創建association mapping。

例子：

... 
class LocationToJobOffer 
{ 
    /** 
    * @ORM\ManyToOne(targetEntity="JobOffer") 
    * @ORM\JoinColumn(name="offer_id", referencedColumnName="id") 
    */ 
    private $jobOffers; 
... 
class JobOffer 
{ 
    /** 
    * @OneToMany(targetEntity="LocationToJobOffer", mappedBy="jobOffers") 
    */ 
    private $locationToJobOffer; 
...

它之後，你的查詢將如下所示：

$query = $this->createQueryBuilder('LocationToJobOffer') 
->select('LocationToJobOffer', 'JobOffers') 
->leftJoint('LocationToJobOffer.jobOffers', 'JobOffers') 
->where('LocationToJobOffer.regionId = 9') 
->getQuery();

我已經試過這個，但是當我添加關聯映射我的應用程序剛剛停止工作時，我會嘗試您的解決方案，並發表評論，如果它的工作，但現在我找到了解決方案。我在下面發佈它。 –

，我發現我的問題的答案。

的appbundle \實體\ 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(); 
    }   
}

而現在一切都工作得很好。
