I am trying to get recursive data.
Following code returns all parents on the top and then the children.
I would like to get data Parent 1 – his children then parent 2 – his children then parent3 – his children.
How do I do this?

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'

    here is a generic solution that the OP can map to their tables/columns:

    set up data 

    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'

    get complete tree 

    ;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

    get tree of given user 

    ;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

    OUTPUT:
