Question

我有一个应用程序服务多级权限和角色

我有这个HIERARCHY：

国家

...地区

........市

............协会

................中心

....................学校

........................类

这个HIERARCHY我把它命名为“EntityLevels”

| ID | Name        | ParentID |
|----|-------------|----------|
| 1  | Country     | Null     |
| 2  | Region      | 1        |
| 3  | City        | 2        |
| 4  | Association | 3        |
| 5  | Center      | 4        |
| 6  | School      | 5        |
| 7  | Class       | 6        |

我还有一个群组表，这意味着乔布斯

| ID | Name               | EntityLevels |
|----|--------------------|--------------|
| 1  | CountryAdmins      | 1            |
| 2  | Region Supervisors | 2            |

用户表如下

| ID | Name  |
|----|-------|
| 1  | User1 |
| 2  | User2 |

现在我有一个UserJobs表或UserGroups

| ID | UserID | GroupdID | EntityID |
|----|--------|----------|----------|
| 1  | User1  | 1        | 1        |
| 2  | User2  | 2        | 2        |
| 3  | User3  | 4        | 38       |

现在问题是如何让每个用户和他的责任取决于他的水平

for eaxmple：

user1必须拥有所有角色和permissoins才能查看其级别下的所有用户，因为他位于Group（1）中，而Group1位于EntityLevel（1）上，而且位于国家级别。

我尝试做类似的事情，但它没有按照预期的方式工作只是在根下没有任何其他孩子给我根

;WITH MyCTE AS (
  SELECT T1.ID, UserId, 0 AS TreeLevel, CAST(T1.ID AS VARCHAR(255)) AS TreePath FROM UserJobs T1
  inner join EntityLevel el on t1.GroupId = el.Id WHERE EL.ParentID IS NULL

  UNION ALL

  SELECT T2.ID, T2.UserId, TreeLevel + 1, CAST(TreePath + '.' + CAST(T2.ID AS VARCHAR(255)) AS VARCHAR(255)) AS TreePath
  FROM UserJobs T2
  inner join EntityLevel el on T2.GroupId = el.Id
  INNER JOIN
  MyCTE itms ON itms.ID = EL.ParentID
)

SELECT ID, TreeLevel, TreePath
FROM  MyCTE 
ORDER BY TreePath;

任何解决方案？

Answer 1

恕我直言，您必须构建整个实体树，然后使用它与其他表一起加入。

看看你想要的结果，我不清楚实体和城市，地区，班级等之间的关系。

显然，根据实体的名称，我知道1 = Country，2 = Region等等，但是我无法找到表模式上允许获取此信息的任何字段：

CASE WHEN Entity.ID = 1 (SELECT Name FROM Country WHERE ID = Entity.ID) END
     WHEN Entity.ID = 2 (SELECT Name FROM Region WHERE ID = Entity.ID) END
     WHEN Entity.ID = 3 (SELECT Name FROM City WHERE ID = Entity.ID) END
     ...
END as EntityName

我建议您构建一个UDF或SP来获取实体的名称，并在下一个脚本中使用它。

;WITH tree AS
(
    SELECT e1.ID, e1.Name, e1.ParentID, [level] = 1
    FROM   EntityLevel e1
    WHERE  e1.ParentID = (SELECT EntityID FROM UserJobs WHERE UserID = 1)
    UNION ALL
    SELECT     e2.ID, e2.Name, e2.ParentID, [level] = tree.[level] + 1
    FROM       EntityLevel e2 
    INNER JOIN tree 
    ON         e2.ParentID = tree.ID
)
SELECT     EntityLevelID, UserName, GroupID, GroupName, EntityID, EntityName
FROM       tree t
INNER JOIN (SELECT gr.entitylevelid, 
                   us.Name UserName, 
                   gr.Name GroupName, 
                   el.Name as EntityName,
                   gr.ID as GroupID,
                   el.ID as EntityID
            FROM   userjobs uj
            INNER JOIN [group] gr
            ON     gr.id = uj.groupid
            INNER JOIN entitylevel el
            ON     el.id = gr.entitylevelid
            INNER JOIN [user] us
            ON us.id = uj.userid) t1
ON t.ID = t1.EntityLevelID
OPTION (MAXRECURSION 0)
;

GO

EntityLevelID | UserName | GroupID | GroupName         | EntityID | EntityName 
------------: | :------- | ------: | :---------------- | -------: | :----------
            2 | User2    |       3 | region admin      |        2 | Region     
            2 | User3    |       4 | region Supervisor |        2 | Region     
            4 | User4    |       5 | manager           |        4 | Association
            5 | user5    |       6 | supervisor        |        5 | Center     
            7 | user6    |       7 | teacher           |        7 | Class

你能试试吗？（评论后编辑）

;WITH MyCTE AS (
  SELECT T1.ID, UserId,  NULL AS PARENT_ID, T1.GroupID, G.EntityLevelID
  FROM UserJobs T1
  INNER JOIN [GROUP] G ON T1.GROUPID = G.ID
  inner join EntityLevel el on G.EntityLevelID = el.Id 
   WHERE T1.UserID = 1  /* Write here the user id you want */
  UNION ALL
  SELECT T2.ID, T2.UserId,  EL.ParentID, T2.GroupID, G.EntityLevelID
  FROM UserJobs T2
  INNER JOIN [GROUP] G ON T2.GROUPID = G.ID
  inner join EntityLevel el on G.EntityLevelID = el.Id
  INNER JOIN MyCTE itms ON EL.ParentID >= itms.ID 
)

SELECT B.*,  C.*, A.*
FROM (SELECT DISTINCT * FROM  MyCTE) A
INNER JOIN [USER] B ON A.UserID = B.ID
INNER JOIN [Group] C ON A.GroupID = C.ID
 ;

输出：

    ID  Name    Mobile  ID  Name    EntityLevelID   ID  UserId  PARENT_ID   GroupID EntityLevelID
