How to find third or nᵗʰ maximum salary from salary table?

Question

How to find third or n^th maximum salary from salary table(EmpID, EmpName, EmpSalary) in optimized way?

Answer 1

Too simple if you use the sub query!

SELECT MIN(EmpSalary) from (
SELECT EmpSalary from Employee ORDER BY EmpSalary DESC LIMIT 3
);

You can here just change the nth value after the LIMIT constraint.

Here in this the Sub query Select EmpSalary from Employee Order by EmpSalary DESC Limit 3; would return the top 3 salaries of the Employees. Out of the result we will choose the Minimum salary using MIN command to get the 3rd TOP salary of the employee.
