You may use OVERLAPS predicate, which is an ANSI SQL standard used in

though) since version 10(?).

Thank you for sharing this info, never heard of it, very useful!

While googling for details I found this article:

http://oraclesponge.wordpress.com/2008/06/12/the-overlaps-predicate/

The author uses this construct everywhere:

date '2007-01-01'

I never saw this syntax and I'm not able to found documentation about it
(perhaps I'm using the wrong keywords...). Can you point me to a link?

Thank you.

Kind regards, Y.
