Question

这是查询：

public function getTeachersBySchool(School $school)
    {  

        $qb2 = $this->getEntityManager()->createQueryBuilder('UserGroup ug')
                ->select('ug.members')
                ->where('ug.school = :school')
                ->andWhere('ug.name = "teachers"')
                ->setParameter('school', $school)    
                ;

        $qb = $this->getEntityManager()->createQueryBuilder('Project\UserBundle\Entity\User u');

        $query = $qb
                ->select('Project\UserBundle\Entity\User')
                ->where($qb->expr()->in('Project\UserBundle\Entity\User', $qb2->getDQL()))   
            ;

        return $query;
    }

我无法理解为什么会出现此错误，尤其是所提出的SQL查询似乎是正确的：

SELECT Project\UserBundle\Entity\User WHERE Project\UserBundle\Entity\User IN(SELECT ug.members WHERE ug.school = :school AND ug.name = "teachers")

编辑：我不认为问题来自andWhere('ug.name = "teachers"')，因为即使删除此行，错误仍然相同。

Answer 2

试试这个：

        $qb2 = $this->getEntityManager()->createQueryBuilder('UserGroup ug')
            ->select('ug.members')
            ->where('ug.school = :school')
            ->andWhere('ug.name = :teachers')
            ->setParameters([
               'school' => $school,
               'teachers' => "teachers"
            ]);

Answer 3

试试这个：

    $qb2 = $this->getEntityManager()->createQueryBuilder()
            ->select('ug.members')
            ->from(UserGroup::class, 'ug')
            ->where('ug.school = :school')
            ->andWhere('ug.name = "teachers"')
            ->setParameter('school', $school);

Querybuilder：错误：字符串的预期结束，得到了＆＃39;（＆＃39;
