what a "Triangular Join" actually is? They just don't teach the good stuff in the schools that are supposed to...
I haven't seen a course that even mentioned that anything other than an equi-join is possible. I showed a join on > recently to a developer I work with and his reaction was "You can do that????"
And then there's the problem that a lot of people don't want to learn. That's a whole nother discussion.
