ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

select * from
(select * from abc where rownum < 9)
-- inner query
where rownum > 4
-- outer query
With respect I wouldn't recommend you suggested approach.
First tables rarely have a rownum field (except in the case of an ID and then the purpose is different)
If you have such a field than multiple selects (an inner to get part of the result and an outer to refine it) is quite inefficient.
Something like that could be done in a single select using a logical AND to join together two WHERE clauses but I would recommend using language constructs when they are available because they are most likely going to be more efficient.
