使用sql server获取递归数据,sql,sql-server-2008,Sql,Sql Server 2008,我正在尝试获取递归数据。下面的代码返回顶部的所有父级，然后返回子级。我想获取数据父1–他的孩子然后是父2–他的孩子然后是父3–他的孩子。我该怎么做 USE Subscriber GO WITH Parent (ParentId, Id, Name,subscriberID) AS ( -- Anchor member definition SELECT A.ParentId,A.id, A.name,A.SubscriberId FROM Subscriber.Budg

我正在尝试获取递归数据。下面的代码返回顶部的所有父级，然后返回子级。我想获取数据父1–他的孩子然后是父2–他的孩子然后是父3–他的孩子。我该怎么做

USE  Subscriber
GO
WITH Parent (ParentId, Id, Name,subscriberID)
AS
(
-- Anchor member definition
    SELECT A.ParentId,A.id, A.name,A.SubscriberId

    FROM Subscriber.Budget.SubscriberCategory AS A   
    WHERE ParentId IS NULL
    UNION ALL
-- Recursive member definition
    SELECT B.ParentId, B.id, B.name,B.SubscriberId

    FROM Subscriber.Budget.SubscriberCategory AS B 

    INNER JOIN Parent AS P


ON B.ParentId = P.Id
)

-- Statement that executes the CTE
SELECT parentId, id, name
FROM Parent
where subscriberID = '1C18093B-5031-42E4-9251-CEF69114365F'

GO

看看游标

我个人不喜欢他们，因为我可以避开他们，但这会让你一次抓住一个家长，然后抓住所有家长的孩子。

这里有一个通用的解决方案，OP可以映射到他们的表/列：

设置数据

DECLARE @Staff table (UserID char(4), UserName varchar(10), ManagerID char(4))
INSERT @Staff VALUES ('ABC1','Jerome', NULL )
INSERT @Staff VALUES ('ABC2','Joe'   ,'ABC1')
INSERT @Staff VALUES ('ABC3','Paul'  ,'ABC2')
INSERT @Staff VALUES ('ABC4','Jack'  ,'ABC3')
INSERT @Staff VALUES ('ABC5','Daniel','ABC3')
INSERT @Staff VALUES ('ABC6','David' ,'ABC2')
INSERT @Staff VALUES ('ABC7','Ian'   ,'ABC6')
INSERT @Staff VALUES ('ABC8','Helen' ,'ABC6')
INSERT @Staff VALUES ('ABC9','Sam'   , NULL)
INSERT @Staff VALUES ('ABD1','Ron'   ,'ABC9')
INSERT @Staff VALUES ('ABD2','Bill'  ,'ABC9')
INSERT @Staff VALUES ('ABD3','Fred'  ,'ABD1')

DECLARE @RootUserID  char(4)
SET @RootUserID='ABC2'

得到完整的树

;WITH StaffTree AS
(
    SELECT 
        UserID, UserName, ManagerID, CONVERT(char(4),NULL) AS ManagerUserID, 1 AS LevelOf
            ,CONVERT(varchar(max),UserID) AS ChainOfCommand
        FROM @Staff
        WHERE ManagerID IS NULL
    UNION ALL
        SELECT 
            s.UserID, s.UserName, s.ManagerID, t.UserID, t.LevelOf+1
                ,ISNULL(t.ChainOfCommand,'')+'|'+s.ManagerID
        FROM StaffTree         t
            INNER JOIN @Staff  s ON t.UserID=s.ManagerID

)
SELECT * FROM StaffTree ORDER BY ChainOfCommand,UserID

获取给定用户的树

;WITH StaffTree AS
(
    SELECT 
        UserID, UserName, ManagerID, CONVERT(char(4),NULL) AS ManagerUserID, 1 AS LevelOf
            ,CONVERT(varchar(max),UserID) AS ChainOfCommand
        FROM @Staff
        WHERE UserID=@RootUserID
    UNION ALL
        SELECT 
            s.UserID, s.UserName, s.ManagerID, t.UserID, t.LevelOf+1
                ,ISNULL(t.ChainOfCommand,'')+'|'+s.ManagerID
        FROM StaffTree         t
            INNER JOIN @Staff  s ON t.UserID=s.ManagerID
        WHERE s.ManagerID=@RootUserID

)
SELECT * FROM StaffTree ORDER BY ChainOfCommand,UserID

输出：

添加一些创建和填充一些测试数据以及预期结果集的tsql如何？My Id和parentID Id都是uniqueidentifier字段，我得到以下错误。Msg 291，级别16，状态1，第5行强制转换或转换：为类型“uniqueidentifier”+1指定的属性无效。远比光标好。但是，那么，我认为诅咒是撒旦发明的…非常感谢你。它就像一个符咒。再次感谢。正如你所说的，游标将是我的最后一个选择，我想尝试上面的解决方案，看起来它会起作用。谢谢你的回复。
