You are right, I didn't get that from your post, though I thought it unlikely you didn't know it. :)

Jared,

Probably it is not clear from my post, but ROWNUM is still useless WITHOUT an order by. And original poster had no clue on what to order by to start with.

Rownum is not necessarily useless for this kind of query. In versions of Oracle (8i+) where an inline view can include an order by, it can be rather
useful.

Top 5 salaries:

select ename, sal
from (

   select ename, sal
   from scott.emp
   order by sal desc
) a
where rownum < 6
