The data you've posted is not a hierarchy; you have no root node, and circular references.

For example, 3 is a child of 2, 2 is a child of 1, and 1 is a child of 3.

Hi,

as per your info provided, check this...

SQL

SELECT UserId, ParentId,name  from yourTable WHERE UserId in
(
 SELECT ParentId from yourTable where UserId=5
)
union
SELECT * from yourTable where ParentId=2

Hope this will give your required output.

Cheers
