I just ran a Google on 'exception join' and came across this link
http://www.freepatentsonline.com/7171398.html
"Outer and exception join to inner join normalization" is the title
on the patent - I recognized a name from my time as a contractor at
IBM in 2001 - and, lo and behold, it is one of the developers of SQE
- hmm - and related patents listed have another developer's name on
them. So this is a bunch of stuff from IBM - IBM makes a big deal of
having a whole bunch of intellectual property patents. Makes for some
interesting reading.
Enjoy!!
