Nth Highest Salary In Sql Server Using Dense Rank Salary 80 000 72 000 50 000 The outer query then selects the first salary from the subquery except we re sorting it ascending this time which sorts from smallest to largest so 50 000 would be the first record sorted ascending As you can see 50 000 is indeed the third highest salary in the example
What Is the Task Here Let s find the third highest salary by department This means finding the third highest value not overall but within each subset where a subset has the salaries for a given department The most helpful tool for doing this is the window functions So here s the first solution using a window function Using NTH VALUE Solution This SQL tutorial will show how the SQL Server window function DENSE RANK can be leveraged to get the nth highest record from a table The SQL Server DENSE RANK function attaches a rank with each row inside the result set partition The DENSE RANK method in contrast to the RANK method returns a series of rank values

5 650 15 63 98 If there are three salaries 10 20 and 20 which is the second highest Is it 20 because the top two are both 20 Or is it 10 because 20 is the highest and 10 is the next highest In other words do you want to fetch the nth highest distinct salary or the nth highest salary Mark Byers Sep 5 2010 at 9 10 2 To find nth highest salary using CTE WITH RESULT AS SELECT SALARY DENSE RANK OVER ORDER BY SALARY DESC AS DENSERANK FROM EMPLOYEES SELECT TOP 1 SALARY FROM RESULT WHERE DENSERANK N To find 2nd highest salary we can use any of the above queries Simple replace N with 2 Similarly to find 3rd highest salary simple replace N with 3
