Hi Mohd Wasif,

Try the following

SQL

SELECT username as Name,
           MAX( CASE seq WHEN 1 THEN department ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 2 THEN department ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 3 THEN department ELSE '' END ) + ', ' +
           MAX( CASE seq WHEN 4 THEN department ELSE '' END ) as Department
      FROM ( SELECT p1.username, p1.department ,
                    ( SELECT COUNT(*)
                        FROM emp p2
                        WHERE p2.username = p1.username
                        AND p2.department <= p1.department )
             FROM emp p1 ) D ( username, department, seq )
     where username='Mohd.wasif' GROUP BY username ;

Thanks

Please try this if you are planning to have as s stored proc.

SQL

BEGIN
DECLARE @DepartmentNames VARCHAR(1000)

DECLARE @UserName AS VARCHAR(20)

SET @UserName = 'Mohd.wasif'

    SELECT @DepartmentNames = COALESCE(@DepartmentNames,'') + Department+ ','
    FROM Emp WHERE UserName = @UserName

SELECT A.* FROM
    (SELECT @UserName AS UserName, @DepartmentNames AS Dept) AS A
--INNER JOIN Register AS B
--ON A.UserName = B.UserName

END
