A Simple and Another Way to Find Rows on n’th Maximum Number from a Table

Introduction

It's a very simple trick to get rows on n^th maximum number from a table. In this tip, I used common table expression (CTE) and DENSE_RANK() function. To know more about CTE, click this link and for DENSE_RANK(), click this link.

Using the Code

A simple code snippet is given below:

    --START TO GET N'TH HIGHEST NUMBER/SALARY

DECLARE @g_query        AS VARCHAR(256)
DECLARE @g_nth_highest  AS INT
DECLARE @g_nth_row      AS INT

SET @g_nth_height = 7;
SET @g_nth_row = 3;

SET @g_query =
    'WITH CTE_RESULT AS
        (
            SELECT ct_salary, DENSE_RANK() OVER
                (
                    ORDER BY ct_salary DESC
                )   AS  DENSERANK_RESULT FROM T_EMPLOYEE
        )
    SELECT TOP '+ CONVERT(VARCHAR, @g_nth_row) + _
    ' ct_salary AS SALARY FROM CTE_RESULT WHERE CTE_RESULT.DENSERANK_RESULT =' + _
    CONVERT(VARCHAR, @g_nth_highest);

    EXEC(@g_query)
-- END

Conclusion

I hope you guys get the scenario and this might be helpful to you. Enjoy!
