Query between two date columns ?

Question

Oracle 11g R2
I'm trying too create a query between two date columns. I have a view that consists of many columns. There are two columns in question called valid_to and valid_from
Part Number     Valid_from        valid_to
100                    01/01/2000       01/01/9999
200                    01/01/2000       01/01/9999
300                    01/01/2000       01/01/9999
etc
If I want to only see rows between with a date range of 01/01/2000 and 01/01/2013 how can I put this as SQL ?
Thanks in advance

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), so that the people who want to help you can re-create the problem and test their ideas.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
See the forum FAQ: https://forums.oracle.com/message/9362002
If you want to find rows that have that exact range, then you can do  something like
SELECT  *
FROM    table_x
WHERE   valid_from  = DATE '2000-01-01
AND     valid_to    = DATE '2013-01-01'
If you want to find rows where any or all or the range on the row overlaps any or all of the 200-2013 target range, then
SELECT  *
FROM    table_x
WHERE   valid_from  <= DATE '2013-01-02
AND     valid_to    >= DATE '2000-01-01'
If you want rows that are enritely within the target range, it's something else.
If you want rows that entirely enclose the target range, it's something else again.
