在 MySQL 中对同一个表使用子查询

我有一张桌子叫Staff它有以下字段：idStaff, Name, Phone, Email, SupervisorId.

The SuervisorId is the idStaff该工作人员的主管。

我想显示所有员工的列表及其基本信息（姓名、电子邮件等）以及主管的姓名。

所以像这样：

select idStaff
     , Name
     , Email
     , Phone
     , (select Name from Staff where idStaff = SupervisorId) as SupervisorName 
  from Staff 
 order 
    by Name ASC

查询不起作用。我尝试连接这两个表，但我对如何从连接中的子查询获取名称感到困惑。

 select idStaff
      , Name
      , Phone
      , Email 
   from Staff a 
  inner 
   join Staff b 
     on a.idStaff = b.SupervisorId 
  order 
     by Name ASC

也许是这样的......

select s1.idStaff
     , s1.Name
     , s1.Email
     , s1.Phone
     , s2.Name as SupervisorName 
from Staff s1
LEFT JOIN Staff s2 ON s1.SupervisorId = s2.idStaff
 order 
    by s1.Name ASC

或者你可以做类似的事情......

select s.idStaff
     , s.Name
     , s.Email
     , s.Phone
     , (select top 1 m.Name from Staff m 
                            where  s.SupervisorId =  m.idStaff) as SupervisorName 
from Staff s
order by s.Name ASC
