How do I limit the number of rows returned by an Oracle query after ordering?

Question

Is there a way to make an Oracle query behave like it contains a MySQL limit clause?

In MySQL, I can do this:

Answer 1

(untested) something like this may do the job

WITH
base AS
(
    select *                   -- get the table
    from sometable
    order by name              -- in the desired order
),
twenty AS
(
    select *                   -- get the first 30 rows
    from base
    where rownum < 30
    order by name              -- in the desired order
)
select *                       -- then get rows 21 .. 30
from twenty
where rownum > 20
order by name                  -- in the desired order

There is also the analytic function rank, that you can use to order by.
