Hierarchy can be implemented using common table expression (CTE).
WITH UserHierarchy ([user_id], [manager_id],[Level]) AS
(
SELECT [user_id],user_ap_mngd_by as manager,0
FROM [user_profile] usrtmp1
WHERE usrtmp1.[user_id]=1
UNION ALL
SELECT usrtmp2.[user_id],user_ap_mngd_by as manager, [Level] + 1
FROM [user_profile] usrtmp2
INNER JOIN UserHierarchy ON
usrtmp2.user_ap_mngd_by = UserHierarchy.[user_id]
)
SELECT * FROM UserHierarchy
