Question

我有以下表结构

表：医生

id name 
1  Mac
2  Smit

表：组织

id name
1  Org1
2 Org2

表：org_doctors

id org_id doctor_id
1   1      1
2   1      2

表：专业化

id name
1 ENT
2 Cardiac

表：doc_specialzations

id doctor_id specialzation_id
1  1          1
2  1          2
3  2          1

以下是我正在处理的学说代码：

$qb = $this->entityManager->createQueryBuilder();
    $qb2 = $qb;
    $qb2->select('dsp.doctor_id')
            ->from('Doctor\Entity\DoctorSpecialization', 'dsp')
            ->where('dsp.specialization = :specializationId')
            ->setParameter('specializationId', $searchBy['specialization']);


    $qb->select('od', 'd', 'o', 'u')
            ->from('Doctor\Entity\OrgDoctor', 'od')
            ->leftJoin('od.organization', 'o')
            ->leftJoin('od.doctor', 'd')
            ->leftJoin('d.user', 'u');


    $qb->where($qb->expr()->in('od.doctor', $qb2->getDQL()));

$qb->andWhere('od.organization IN (:organizations)')
                ->andWhere('d.active = true')
                ->andWhere('od.active = true')
                ->setParameter('organizations', $organizations);

在处理abvoe代码时，我收到以下错误：

[Syntax Error] line 0, col 188: Error: Expected Doctrine\\ORM\\Query\\Lexer::T_FROM, got ','

这是我的DoctorSpecialization实体：

/**
 * @ORM\Entity
 * @ORM\Table(name="doctors_specializations")
 */

class DoctorSpecialization extends BaseEntity{

    /**
     * @ORM\ManyToOne(targetEntity="Doctor\Entity\Doctor", inversedBy="docSpecialization")
     * @ORM\JoinColumn(name="doctor_id",referencedColumnName="id",nullable=false)
     */
    protected $doctor;

    /**
     * @ORM\ManyToOne(targetEntity="Doctor\Entity\Specialization", inversedBy="docSpecialization")
     * @ORM\JoinColumn(name="specialization_id", referencedColumnName="id", nullable=false)
     */
    protected $specialization;

    public function setDoctor(Doctor $doctor = null)
    {
        $this->doctor = $doctor;

        return $this;
    }

    public function getDoctor()
    {
        return $this->doctor;
    } 

    public function setSpecialization(Specialization $specialization = null)
    {
        $this->specialization = $specialization;

        return $this;
    }

    public function getSpecialization()
    {
        return $this->specialization;
    }  

}

你能尝试一下这个代码吗...你的IMO有错误......

    //don't use the same query builder for the two querys
    $qb = $this->entityManager->createQueryBuilder();
    $qb2 = $this->entityManager->createQueryBuilder();

    $qb2->select('dsp.doctor')
            ->from('Doctor\Entity\DoctorSpecialization', 'dsp')
            //You are searching by specializationId so join with especialization
            ->leftJoin('dsp.specialization', 'esp')
            ->where('esp.id = :specializationId')
            ->setParameter('specializationId', $searchBy['specialization']);


    $qb->select('od', 'd', 'o', 'u')
            ->from('Doctor\Entity\OrgDoctor', 'od')
            ->leftJoin('od.organization', 'o')
            ->leftJoin('od.doctor', 'd')
            ->leftJoin('d.user', 'u');

    $qb->where($qb->expr()->in('od.doctor', $qb2->getDQL()));
    //If organizations is an array of ids => o.id... if is an array of entities your code where rigth here
    $qb->andWhere('o.id IN (:organizations)')
                ->andWhere('d.active = true')
                ->andWhere('od.active = true')
                ->setParameter('organizations', $organizations);

祝你好运

注意：您还可以使用@ ORM / Column注释将doctor_id和specialization_id声明为您的实体中的私有/受保护属性，这与已声明的关系不冲突并促进查询，因为你不必加入实体（在这种情况下是especialitation），但我不知道这是非常好的做法

另一个答案，我昨天在思考这个问题并且你不需要子查询，只需要两个连接并修改查询子句

$qb = $this->entityManager->createQueryBuilder();
$qb->select('od', 'd', 'o', 'u')
        ->from('Doctor\Entity\OrgDoctor', 'od')
        ->leftJoin('od.organization', 'o')
        ->leftJoin('od.doctor', 'd')
        ->leftJoin('d.doctor_specialization', 'dsp')
        ->leftJoin('dsp.specialization', 'esp')
        ->leftJoin('d.user', 'u');

$qb->where('esp.id = :specializationId')
//If organizations is an array of ids => o.id... if is an array of entities your code where rigth here
   ->andWhere('o.id IN (:organizations)')
            ->andWhere('d.active = true')
            ->andWhere('od.active = true')
            ->setParameter('specializationId', $searchBy['specialization'])
            ->setParameter('organizations', $organizations);

祝你好运

在doctrine2查询生成器中的子查询内查询不起作用
