Sql server 从AD创建员工和经理列表

我有一张员工及其经理的表格：

-- Show the contents of the table
SELECT * FROM ActiveDirectory.dbo.ADUser

Last        First   ManagerDN
Johnson     Brent   CN=Jones\, Bob,OU=IT
Poleman     Debbie  CN=Jones\, Bob,OU=IT
Kismain     Lenni   CN=Jones\, Bob,OU=IT
Braiswool   Marc    CN=Jones\, Bob,OU=IT
Garpial     Pat     CN=Johnson\, Brent,OU=IT
McKinnis    Laurie  CN=Kismain\, Lenni,OU=IT
Thomason    Maddy   CN=Poleman\, Debbie,OU=IT
Dodgers     Kevin   CN=Thomason\, Maddy,OU=IT

我想创建一个员工、他们的经理和他们的经理的列表。为简单起见，假设可以有3个级别：

LastName    FirstName   ManagerDN3                  ManagerDN2                  ManagerDN1
                                                    CN=Braiswool\, Marc,OU=IT   CN=Jones\, Bob,OU=IT
                        CN=Garpial\, Pat,OU=IT      CN=Johnson\, Brent,OU=IT    CN=Jones\, Bob,OU=IT
                        CN=McKinnis\,Laurie,OU=IT   CN=Kismain\, Lenni,OU=IT    CN=Jones\, Bob,OU=IT
                        CN=Thomason\, Maddy,OU=IT   CN=Poleman\, Debbie,OU=IT   CN=Jones\, Bob,OU=IT
Dodgers     Kevin       CN=Thomason\, Maddy,OU=IT   CN=Poleman\, Debbie,OU=IT   CN=Jones\, Bob,OU=IT

以下是创建和填充表的代码：

-- Create the ADUser table
CREATE TABLE [dbo].[ADUser](
    [Last] [nvarchar](50) NOT NULL,
    [First] [nvarchar](50) NOT NULL,
    [ManagerDN] [nvarchar](50) NOT NULL
)

-- Populate the ADUser table
INSERT INTO [ActiveDirectory].[dbo].[ADUser]
           ([Last]
           ,[First]
           ,[ManagerDN])

SELECT 'Johnson','Brent','CN=Jones\, Bob,OU=IT'
UNION ALL 
SELECT 'Poleman','Debbie','CN=Jones\, Bob,OU=IT'
UNION ALL 
SELECT 'Kismain','Lenni','CN=Jones\, Bob,OU=IT'
UNION ALL 
SELECT 'Braiswool','Marc','CN=Jones\, Bob,OU=IT'
UNION ALL 
SELECT 'Garpial','Pat','CN=Johnson\, Brent,OU=IT'
UNION ALL 
SELECT 'McKinnis','Laurie','CN=Kismain\, Lenni,OU=IT'
UNION ALL 
SELECT 'Thomason','Maddy','CN=Poleman\, Debbie,OU=IT'
UNION ALL 
SELECT 'Dodgers','Kevin','CN=Thomason\, Maddy,OU=IT'

然后我可以查询每个列：

-- Show the Level2 Managers (ManagerDN2)
SELECT Last, First, ManagerDN FROM dbo.ADUser
WHERE ManagerDN = 'CN=Jones\, Bob,OU=IT'

-- Show the Level3 Managers (ManagerDN3)
SELECT Last, First, ManagerDN FROM dbo.ADUser
WHERE ManagerDN IN 
(   SELECT 'CN=' + Last + '\, ' + First + ',OU=IT'
    FROM dbo.ADUser
    WHERE ManagerDN = 'CN=Jones\, Bob,OU=IT'
)

-- Show the Employees
SELECT Last, First, ManagerDN FROM dbo.ADUser
WHERE ManagerDN IN 
(
    SELECT 'CN=' + Last + '\, ' + First + ',OU=IT'
    FROM dbo.ADUser
    WHERE ManagerDN IN 
    (   SELECT 'CN=' + Last + '\, ' + First + ',OU=IT'
        FROM dbo.ADUser
        WHERE ManagerDN = 'CN=Jones\, Bob,OU=IT'
        )
)

如何有效地创建员工及其经理及其经理的列表

谢谢

为什么不为每个用户提供一个唯一的Id

然后，您可以使用具有此Id的外键链接到某人的经理

但是，如果设置了模式，并且没有办法更改它，您可以查找。

我喜欢它！递归CTE非常适合这种情况。
