Best way is using CORRELATED SUBQUERY : as belowSelect * From TableName T1 Where (N-1) = (Select Count(Distinct(E2.ColumnName)) From TableName T2 Where T2.ColumnName > T1.ColumnName)For Required Case We can use it as :-Select * From EMP T1 Where (2-1) = (Select Count(Distinct(E2.sal)) From EMP T2 Where T2.sal > T1.sal)

For this 2 ways are there.

1.select sal from (select sal from emp order by sal desc) where rownum e2.salary

But first approach is best approach because in second case one row of first table is compared with all the rows of second table.So performance will be reduced.

Hi..

your query returns fisrt 5 max salaries but the question is nth maximum salary so your query will be :

select min(salary) Salary from (select salary from employees where salary is NOT NULL order by salary desc) where rownum < = 5

here it will show 5th max salary.

Try this and let me know if my query is wrong.
