php - Doctrine DQL Invalid parameter number：绑定变量的数量与标记的数量不匹配

Question

我收到Invalid parameter number: number of bound variables does not match number of tokens此查询的错误。

我真的没有看到问题，有什么想法吗？

public function getByPartial($q, Company $company)
{

    $query = $this->createQueryBuilder('u')
        ->join('u.company',':company')
        ->where('u.firstName LIKE :q')
        ->orWhere('u.lastName LIKE :q')
        ->setParameters(array('company' => $company, 'q' => '%'.$q.'%'))
        ->getQuery();
    return $query->getResult();

}

Answer 1

company 不能是参数，您只需指定一个别名，例如：

public function getByPartial($q, Company $company)
{
    $query = $this->createQueryBuilder('u')
        ->addSelect('c')
        ->join('u.company','c')
        ->where('u.firstName LIKE :q OR u.lastName LIKE :q')
        ->andWhere('c.id = :companyId')
        ->setParameters(array('companyId' => $company->getId(), 'q' => '%'.$q.'%'))
        ->getQuery();
    return $query->getResult();
}

Answer 2

您必须传递确切数量的参数。

public function getByPartial($q, Company $company)
{
    $query = $this->createQueryBuilder('u')
        ->join('u.company','c')
        ->where('u.firstName LIKE :q1 OR u.lastName LIKE :q2')
        ->andWhere('c.id = :company_id')
        ->setParameters(array('company_id' => $company->getId(), 'q1' => '%'.$q.'%', 'q2' => '%'.$q.'%'))
        ->getQuery();
    return $query->getResult();
}
