主义createQueryBuilder返回意外结果

Question

我有以下实体：

车辆-参考表，用于存储下一个实体之间的关联 使 模型 子模型

现在，根据车辆的“年份”和“品牌”，我试图返回可用的子模型，或者如果给定的车辆不可用，则不返回任何子模型。在我的示例中，$ make ='Mazda'和$ year ='2016'

由于某种原因，以下查询在不应该返回任何子模型时，返回属于Kia：D的子模型。我在做什么错了？

        $qb = $this->createQueryBuilder('submodel');
        $qb->select('submodel', 'vehicles')
        ->join('submodel.vehicles', 'vehicles')
        ->join('vehicles.make', 'make')
        ->Where('make.makeName = :makeName')->setParameter('makeName', $makeName)
        ->AndWhere('vehicles.year = :year')->setParameter('year', $year);
        $results = $qb->getQuery()->getResult();

车辆实体：
