我想用用户信息左键加入一对一用户

用户信息将uid作为唯一密钥，并引用用户id

---

在uid=用户id的情况下，我如何离开连接并从用户信息获取数据？

您必须在实体之间创建关系。 如果您想要一个oneToOne关系：

class User
{
    /**
     * @ORM\Id
     */
    protected $id;

    /**
     * @ORM\OneToOne(targetEntity="UserInformation")
     */
    protected $userInformation;
}

class UserInformation
{
    /**
     * @ORM\Id
     */
    protected $id;

    /**
     * @ORM\OneToOne(targetEntity="User", inversedBy="userInformation")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
     */
    protected $uid;
}

内部联接：

$user = $repository
  ->createQueryBuilder('u')
  ->addSelect('ui') // to limit queries when doing $user->getUserInformation()
  ->innerJoin('u.userInformation', 'ui')
  ->where('u.email = :email')->setParameter('email', $email);

“ui WHERE u.email”：错误：Class App\Entity\Users没有名为userInformation的关联您是否有行

受保护的$userInformation？“ui WHERE u.email”：错误：Class App\Entity\Users没有名为userInformation的关联您是否有行
受保护的$userInformation？
