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

If you want optimize way means use TOP Keyword, So the nth max and min salaries query as follows but the queries look like a tricky as in reverse order by using aggregate function names:

N maximum salary:

SELECT MIN(EmpSalary)
FROM Salary
WHERE EmpSalary IN(SELECT TOP N EmpSalary FROM Salary ORDER BY EmpSalary DESC) 

for Ex: 3 maximum salary:

SELECT MIN(EmpSalary)
FROM Salary
WHERE EmpSalary IN(SELECT TOP 3 EmpSalary FROM Salary ORDER BY EmpSalary DESC) 

N minimum salary:

SELECT MAX(EmpSalary)
FROM Salary
WHERE EmpSalary IN(SELECT TOP N EmpSalary FROM Salary ORDER BY EmpSalary ASC)

for Ex: 3 minimum salary:

SELECT MAX(EmpSalary)
FROM Salary
WHERE EmpSalary IN(SELECT TOP 3 EmpSalary FROM Salary ORDER BY EmpSalary ASC)

Answer 2

Method 1:

SELECT TOP 1 salary FROM (
SELECT TOP 3 salary 
 FROM employees 
  ORDER BY salary DESC) AS emp 
 ORDER BY salary ASC

Method 2:

  Select EmpName,salary from
  (
    select EmpName,salary ,Row_Number() over(order by salary desc) as rowid      
     from EmpTbl)
   as a where rowid=3

Answer 3

set @n = $n

SELECT a.* FROM ( select a.* , @rn = @rn+1  from EMPLOYEE order by a.EmpSalary desc ) As a  where rn = @n

Answer 4

To query the nth highest bonus, say n=10, using AdventureWorks2012, Try Following code

USE AdventureWorks2012; 
GO

SELECT * FROM Sales.SalesPerson;
GO

DECLARE @grade INT;
SET @grade = 10;
SELECT MIN(Bonus)
FROM (SELECT TOP (@grade) Bonus FROM (SELECT DISTINCT(Bonus) FROM Sales.SalesPerson) AS a ORDER BY Bonus DESC) AS g

Answer 5

Try this Query

SELECT DISTINCT salary
FROM emp E WHERE
&no =(SELECT COUNT(DISTINCT salary) 
FROM emp WHERE E.salary <= salary)

Put n= which value you want

Answer 6

Try this code :-

SELECT *
   FROM one one1
   WHERE ( n ) = ( SELECT COUNT( one2.salary )
                   FROM one one2
                   WHERE one2.salary >= one1.salary
                 )
