Given 2 date ranges, the overlaps functions returns TRUE or FALSE. I
want to find the # of days that are overlapping. Is there a "built in"
way to do this? Should I just write a function to do it?
For instance, this example overlaps, but I want to know how much does
it overlap?
SELECT (DATE '2001-02-16', DATE '2001-12-21') OVERLAPS
(DATE '2001-10-30', DATE '2002-10-30');
Thanks in advance!
