Solution 3

SQL

DECLARE @tmp as Table(ID int,EmpName varchar(10),ManagerID int)
INSERT INTO @tmp  SELECT 1,'Kiran',null
INSERT INTO @tmp  SELECT 2,'Stephen',1
INSERT INTO @tmp  SELECT 3,'Basha',2
INSERT INTO @tmp  SELECT 4,'Surya',3

SELECT
    t1.*,
    t2.EmpName ManagerName
FROM @tmp t1
    LEFT JOIN @tmp t2
ON  t1.ManagerID = t2.ID
