Using ROW_NUMBER() to find the second highest in Sql Server

Have this query (see below): I want to be able to use the ROW_NUMBER() function to return the record with the 2nd highest salary. I know how to use the function but I can't figure out where to put it since I have a subquery.

The query returns:

Yuriana Hagasawa    NULL    China   Project Manager 56000.00
Venessa Katarina    Cameron Denmark     Tech Lead   185000.00
Sahi    King    NULL    Denmark     Design Engineer 156000.00
Chen    Chen    NULL    Andorra     Project Manager 76000.00

so, using the row number function I want to only return the record with sahi king. Thanks.

SELECT C.[First Name],
C.[Last Name],
C.[Middle Name],
C.[Country Name],
C.[Designation Name],
Salary.Emp_Salary AS 'Current Salary'
    FROM
    (
    SELECT
        Emp_First_Name AS "First Name",
        Emp_Last_Name AS "Last Name",
        Emp_Middle_Name AS "Middle Name",
        Country_Name AS "Country Name",
        Desig_Name as "Designation Name",
        MAX(Emp_Salary_Change_Year) AS "Change Year"

        FROM Employee_Details AS e

    INNER JOIN Country AS co ON e.Emp_Country_Id = co.Country_Id
    INNER JOIN State AS s ON e.Emp_State_Id = s.State_Id
    INNER JOIN Designation AS d ON e.Desig_Id = d.Desig_Id
    INNER JOIN Salary AS sa ON e.Emp_Id = sa.Emp_Id

    GROUP BY Emp_First_Name, Emp_Last_Name,
    Emp_Middle_Name, Country_Name, Desig_Name) AS C
    INNER JOIN Salary ON C.[Change Year] = Salary.Emp_Salary_Change_Year;

You can try the ROW_NUMBER with ORDER BY Salary.Emp_Salary DESC as below for this and if you need only the second highest then add a where condition WHERE RowNo = 2 below.

SELECT * FROM (
SELECT C.[First Name],
    C.[Last Name],
    C.[Middle Name],
    C.[Country Name],
    C.[Designation Name],
    Salary.Emp_Salary AS 'Current Salary',
    ROW_NUMBER() OVER (ORDER BY Salary.Emp_Salary DESC) As RowNo
        FROM
        (
        SELECT
            Emp_First_Name AS "First Name",
            Emp_Last_Name AS "Last Name",
            Emp_Middle_Name AS "Middle Name",
            Country_Name AS "Country Name",
            Desig_Name as "Designation Name",
            MAX(Emp_Salary_Change_Year) AS "Change Year"

            FROM Employee_Details AS e

        INNER JOIN Country AS co ON e.Emp_Country_Id = co.Country_Id
        INNER JOIN State AS s ON e.Emp_State_Id = s.State_Id
        INNER JOIN Designation AS d ON e.Desig_Id = d.Desig_Id
        INNER JOIN Salary AS sa ON e.Emp_Id = sa.Emp_Id

        GROUP BY Emp_First_Name, Emp_Last_Name,
        Emp_Middle_Name, Country_Name, Desig_Name) AS C
        INNER JOIN Salary ON C.[Change Year] = Salary.Emp_Salary_Change_Year) t
WHERE RowNo = 2;
