Mysql 内部联接-在每行上选择2个参数

我有一个名为timesheet的表和一个名为user的表。在user中，我得到name和timesheet，在user中得到userIDID，myIDlast被修改

表-用户

表-时间表

我也想看看是谁修改了用户的密码

像

如何匹配myID和Name并添加另一个变量

userID=4

myID=5

4=安德斯

5=埃里克

"SELECT * FROM timesheet INNER JOIN user ON (timesheet.userID = user.ID) WHERE userID=$user";

---

您必须对时间表表执行两次JOIN use table，如：

select u1.name as Name, u2.name as Modified, t.info, t.order
from timesheet t
JOIN user u1 on t.userID = u1.ID
JOIN user u2 on t.myID u1.ID

Name   | Modified | info | order |

"SELECT * FROM timesheet INNER JOIN user ON (timesheet.userID = user.ID) WHERE userID=$user";

SELECT
  ua.Name,
  up.Name AS Modified,
  ua.info,
  ua.order
FROM
  timesheet t INNER JOIN user ua
ON
  ua.ID=t.userID INNER JOIN user up
ON
  up.ID=t.myID
WHERE
  ua.ID = ?;

select u1.name as Name, u2.name as Modified, t.info, t.order
from timesheet t
JOIN user u1 on t.userID = u1.ID
JOIN user u2 on t.myID u1.ID
