How to find Nth Highest Salary of Employee

This question is quite a popular question and it is interesting that I have been receiving this question every other day. I have already answer this question here. “How to find Nth Highest Salary of Employee”.

Please read my article here to find Nth Highest Salary of Employee table : SQL SERVER – Query to Retrieve the Nth Maximum value

I have re-wrote the same article here with example of SQL Server 2005 Database AdventureWorks : SQL SERVER – 2005 – Find Nth Highest Record from Database Table

Just a day ago, I have received another script to get the same result from one of the blog reader Pravin Phatangare, let us see his simple method here.

For particular example of employee :

How to get 1st, 2nd, 3rd, 4th, nth topmost salary from an Employee table

The following solution is for getting 6th highest salary from Employee table ,
SELECT TOP 1 salary
FROM (
SELECT DISTINCT TOP 6 salary
FROM employee
ORDER BY salary DESC) a
ORDER BY salary
You can change and use it for getting nth highest salary from Employee table as follows
SELECT TOP 1 salary
FROM (
SELECT DISTINCT TOP n salary
FROM employee
ORDER BY salary DESC) a
ORDER BY salary
where n > 1 (n is always greater than one)

Same example converted in SQL Server 2005 to work with Database AdventureWorks.
USE AdventureWorks;
GO
SELECT TOP 1 Rate
FROM (
SELECT DISTINCT TOP 4 Rate
FROM HumanResources.EmployeePayHistory
ORDER BY Rate DESC) A
ORDER BY Rate
GO
