Bryan this sounds EXACTLY like what I was looking for.  Thanks, I will checkout 10.4.

If I understand your question correctly, in Derby we call these
"Table Functions", and they have been added to Derby recently:
https://issues.apache.org/jira/browse/DERBY-716

This feature will be part of Derby 10.4, which progress you can
follow here: http://wiki.apache.org/db-derby/DerbyTenFourRelease

We'd love to have some feedback about how well this feature works
for you, so please give it a try and let us know!

thanks,

bryan
