symfony3, Doktrin, leftJoin

Question

Ich suchte das Forum in jeder Hinsicht und versuchte jede Lösung, die ich finden konnte. Leider hat nichts geklappt. Ich muss leftJoin in der Lehre verwenden und kann nicht menage. In php my admin funktioniert alles einwandfrei.

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 

Ich versuchte Anmerkung Verbände und Vereine und alle möglichen Variationen Querybuilder zu verwenden. Jedes Mal habe ich einen anderen Fehler bekommen.

Meine Einheiten (I ommited Getter und Setter):

Können Sie mir zeigen in die richtige Richtung damit bitte? Vielen Dank im Voraus.

Answer 1

Zuerst müssen Sie association mapping erstellen.

Beispiel:

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

Nachdem es, deine Abfrage wird wie folgt aussehen:

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

Answer 2

ich die Antwort für mein Problem gefunden.

AppBundle \ Entity \ 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(); 
    }   
} 

Und alles funktioniert jetzt einwandfrei.
