I just saw this topic today. I also saw comments of various dbas regarding your query but was
not impressed by anyone.
You can successfully use this query and i bet this will not give you any problems:

select salary from employee x where 20 >
(select count(*) from employee y where y.salary > x.salary) order by
x.salary desc;

However if the u want to have top 20 distinct salaries then add distinct clause.
