Sql server 在sqlserver中连接3个非常复杂的表

我想去

 i have 3 tables (employee,structure,District)

 1_employee table contains  empid,workid  and actuallwork  fks to structid 
 2_ structure table contains structid , districtId fk to district
 3_District table contains districtid , districtname

---

，ActualWork（外键actulalwork中的disitrict名称）

如果为每个事件指定了不同的别名，则可以在查询中多次使用同一个表。结构和地区列出两次，第一次作为工作/地区，第二次作为实际工作/实际严格。这就是在处理对同一表的多个引用时如何区分列的来源

empid  ,  work 

select employee.empid,
       district.districtname,
       actualdistrict.districtname acturaldistrictname
  from employee
    inner join structure work
       on employee.workid = work.structid
    inner join district
       on work.districtfk = district.districtid
    inner join structure actualwork
       on employee.actuallworkfk = actualwork.structid
    inner join district actualdistrict
       on actualwork.districtfk = actualdistrict.districtid
