If you just want to select all entries created between two given dates, the
following query should do it:

SELECT column1, column2, ....
FROM table
WHERE creation_date between to_date('date1','date_format') and
to_date('date2','date_format')
order by creation_date;

This will find all the entries with a creation_date between date1 and date2
and it return the rows sorted by the creation date. You can add additional
selection critirias to the WHERE clause if needed.
