Doctrine 2 WHERE IN子句使用实体集合

Question

我正在尝试在Doctrine 2中构建一个查询,该查询查找Vacancy与任何给定VacancyWorkingHours实体相关的所有实体.

该Vacancy实体看起来如下:

/**
 * Vacancy
 *
 * @ORM\Table(name="vacancy")
 * @ORM\Entity(repositoryClass="JaikDean\CareersBundle\Entity\VacancyRepository")
 */
class Vacancy
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var VacancyWorkingHours
     *
     * @ORM\ManyToOne(targetEntity="VacancyWorkingHours", inversedBy="vacancies")
     * @ORM\JoinColumn(name="vacancy_working_hours_id", referencedColumnName="id")
     **/
    private $workingHours;

    /* Other fields and methods are inconsequential */
}

我的查询当前看起来如下,但由于where子句没有返回结果.在此示例中,$workingHours是Doctrine\Common\Collections\ArrayCollection包含许多VacancyWorkingHours实体的实例

$q = $this->createQueryBuilder('v')
    ->select('v')
    ->andWhere('v.workingHours IN (:workingHours)')
    ->setParameter('workingHours', $workingHours->toArray());
;

Answer 1

我对此提出的拉取请求已合并到Doctrine ORM 2.5中,因此您现在可以执行此操作:

$q = $this->createQueryBuilder('v')
    ->select('v')
    ->andWhere('v.workingHours IN (:workingHours)')
    ->setParameter('workingHours', $workingHours);
;

最新版本的Doctrine现在允许收集参数,并将自动使用每个集合条目的主键.

Answer 2

尝试将ID设置为参数

$ids = array();
foreach($workingHours as $w) {
    $ids[] = $w->getId();
}

然后

$q = $this->createQueryBuilder('v')
    ->select('v')
    ->andWhere('v.workingHours IN (:workingHours)')
    ->setParameter('workingHours', $ids);
;
