Question

所以这就是问题，我有两张桌子：

table1包含列intUsersID, varUsersName
table2包含列intCouriers, intResponsible

intCouriers（有一些intursersID是Couriers）和intResponsible（有一些负责任的intUsersID）

在我的查询中，我必须看到信使和负责人的用户名类似的东西：

SELECT 
    table1.varUsersName 'Couriers',
    table1.varUsersName 'Responsible'
FROM
    table1 
LEFT JOIN 
    table2 ON table2.intCouriers = table1.intUsersID

然后我需要一些如何子查询或加入这个“table1.varUsersName'Deponsible'”，以获得'Reponsible'人员。请帮帮我。

Answer 1

应该是这个

SELECT table1.varUsersName 'Couriers', table2.varUsersName 'Responsible'
FROM table1 
INNER JOIN table3  on table1.intUsersID = table3.intCouriers
INNER JOIN table1  as Table2 on  table2.intUsersID = table3. intResponsible

Mysql需要从table1中获取一列两次，然后通过table2的两个不同列对它们进行排序
