    There are two ways
    - Using LIMIT clause
    - Special SQL

    Using LIMIT there are issues that if table has got same salary (field) value multiple times, but this will show you only one record, then you will not get to know that there are also others with same salary.

    Another SQL Approach is -
    -------------
    select a.empid, a.salary from employees as a
    where 2 =(select count(distinct b.salary) from employees as b
    where b.salary >=a.salary)
    ---------------
    this query will return you all the rows which comes under this criteria.

    select * from TABLENAME where salary=(select salary from TABLENAME order by salary desc limit 4,1)


    The following example is for the 6th highest :-
    select * from TABLENAME where salary=(select salary from TABLENAME order by salary desc limit 6,1)
