Question

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

Answer 1

Try this

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

For 3 you can replace any value...

Answer 2

To get third highest value from table

SELECT * FROM tableName ORDER BY columnName DESC LIMIT 2, 1

Answer 3

--nth highest salary

select * 
from (select lstName, salary, row_number() over( order by salary desc) as rn 
      from employee) tmp
where rn = 2

--(nth -1) highest salary

select * 
from employee e1
where 1 = (select count(distinct salary)  
           from employee e2
           where e2.Salary > e1.Salary )

Answer 4

declare @maxNthSal as nvarchar(20)
SELECT TOP 3 @maxNthSal=GRN_NAME FROM GRN_HDR   ORDER BY GRN_NAME DESC
print @maxNthSal

Answer 5

By subquery:

SELECT salary from
(SELECT rownum ID, EmpSalary salary from
(SELECT DISTINCT EmpSalary from salary_table order by EmpSalary DESC)
where ID = nth)

Answer 6

Replace N with your Max Number

SELECT *
FROM Employee Emp1
WHERE (N-1) = (
SELECT COUNT(DISTINCT(Emp2.Salary))
FROM Employee Emp2
WHERE Emp2.Salary > Emp1.Salary)

Explanation

The query above can be quite confusing if you have not seen anything like it before – the inner query is what’s called a correlated sub-query because the inner query (the subquery) uses a value from the outer query (in this case the Emp1 table) in it’s WHERE clause.
