1. If negative transactions are possible, than my query is incorrect.
2. You probably need a much larger set of test data to test different
approaches against. Also I would say there are at lest 2 possible
situations:
- most transactions are already negated.
- most transactions have not been negated yet.
In some cases in different situations different queries are the best. I
would try both and see if one and the same query is the best.
Good luck!
