Do you know of a reference that explains these variations succinctly - I must admit my breadth of vendor quotient is quite low.

Until now I had assumed most (if not all) performed the 3VL fandango in the same direction around the dance floor - especially the (NULL == NULL) is FALSE outcome.

I had (previously?) thought the angst in this issue was more driven by ppl being aggravated by the "apparently" non-sensical outcomes when NULL values appear in join elements and/or procedural code and lead to unexpected results (bugs).
