    /*Using Common Table Expression*/ /* n=10 */
    WITH Result as (Select Salary, Dense_Rank OVER (ORDER BY salary desc) as Dense_Rank from Employees)
    SELECT salary
    from Result
    WHERE Dense_Rank =n;

    /*Using LIMIT and OFFSET*/
    Select *from Employees
    Where Salary =(Select Distinct(Salary) from Employees Order by salary LIMIT n-1,1);

    Select * from (
    select ename,sal,dense_rank() OVER(order by sal desc)r from employee)
    where r = 10

    Explanation:
    we will use the window function dense_rank() to rank according to descending
    salaries and filter the rows which are getting a rank of 10
