typeorm 连接与查询构建器

Question

我正在使用 typeorm join 而不在表中建立关系。这是我的查询：

let query = userRepository.createQueryBuilder("u")
    .where("u.academicYear = :year", { year })
    .leftJoinAndMapOne("u.educationalDetails", EducationalDetails, "e", "u.id = e.userId")
    .leftJoinAndMapOne("u.preferences", Preferences, "p", "u.id = p.userId")
    .leftJoinAndMapOne("u.phdEducationalDetails", PhdEducationalDetails, "ep", "u.id = ep.userId")
    .leftJoinAndMapOne("u.order", Order, "o", "u.serialNo = o.serialNo");

  isWhatsappNoSame: null,
  domicileState: null,
  educationalDetails: [EducationalDetails],
  preferences: [Preferences],
  phdEducationalDetails: null,
  order: null
},

这就是我得到结果的方式。我想要这一切都在一个对象中。我们可以这样做吗？在这里我先进入数组，然后进入对象

我可以在一个对象中解决这个问题吗？我也无法使用这种关系。我想在与他们没有任何关系的情况下做到这一点
