Question

I have a table X with records:

rec# start end 
===============
100  2000  2020 
101  2004  2005 
102  2006  2007

I try:

            SELECT * from X where start >= 2004 and end <= 2005;

and

            SELECT * from X where start BETWEEN 2004 and 2005;

In both cases I (correctly) get rec# 101 as the result.
But I need to also be retrieving rec# 100 because the range (2004-2005) is included in the 2000-2020 record.

Thank you for any help…

Sounds like you have your inequalities around the wrong way:

SELECT * FROM X WHERE start <= 2004 AND end >= 2005

This will return all records which contain the interval [2004,2005].

See it on sqlfiddle.
