【问题描述】：

在我的应用程序中，会员有权管理每个任务。给予会员许可的方式是， 每个成员被分配到单独的组，每个组都有单独的权限。所以每个组的成员都会收到该组的权限。

我有以下表格结构，

组

+---------+------+
| GroupID | Name |
+---------+------+
| G1       | YYY  |
+---------+------+
| G2       | XXX  |
+---------+------+
| G3       | UUU  |
+---------+------+

授权

+-----------------+-------------------+
| AuthorizationID | AuthorizationName |
+-----------------+-------------------+
| AUTH1           | Delete            |
+-----------------+-------------------+
| AUTH2           | Send              |
+-----------------+-------------------+
| AUTH3           | ADD               |
+-----------------+-------------------+

会员

+----------+------+
| MemberID | Name |
+----------+------+
| 1        | PAUL |
+----------+------+
| 2        | JHON |
+----------+------+
| 3        | AMBE |
+----------+------+
| 4        | NISH |
+----------+------+

组授权

+----------------------+-----------+-------------------+
| GroupAuthorizationID | FKGroupID | FkAuthorizationID |
+----------------------+-----------+-------------------+
| 1                    | G1        | AUTH1             |
+----------------------+-----------+-------------------+
| 2                    | G2        | AUTH1             |
+----------------------+-----------+-------------------+
| 3                    | G1        | AUTH2             |
+----------------------+-----------+-------------------+
| 4                    | G3        | AUTH1             |
+----------------------+-----------+-------------------+

会员组

+---------------+-----------+------------+
| MemberGroupID | FKGroupID | FKMemberID |
+---------------+-----------+------------+
| 1             | G1        | 1          |
+---------------+-----------+------------+
| 2             | G2        | 1          |
+---------------+-----------+------------+
| 3             | G4        | 2          |
+---------------+-----------+------------+
| 4             | G4        | 3          |
+---------------+-----------+------------+

我需要获取所有具有发送授权的用户。我怎样才能给它写一个连接查询。

【参考方案1】：

Select M.name, A.Authorization
FROM Authorization A INNER JOIN GroupAuthorization GA 
ON A.AuthorizationID = GA.FkAuthorizationID
INNER JOIN MemberGroup MG 
ON MG.FKGroupID  = GA.FKGroupID 
INNER JOIN Memeber M ON M.MemberID  = MG.FKMemberID 
where A.AuthorizationName  = 'Send'
