    | 2  | 200    |
    | 3  | 300    |

Answer 1

I would use DENSE_RANK() & do LEFT JOIN with employee table :

SELECT t.Seq, e.*
FROM ( VALUES (2) 
     ) t (Seq) LEFT JOIN
     (SELECT e.*,
             DENSE_RANK() OVER (ORDER BY Salary DESC) AS Num
      FROM Employee e
     ) e 
     ON e.Num = t.Seq;
