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.
