Hi, I've been given a large set of data to transform, and while I think the task would be relatively simple to complete by making a quick macro, I imagine there should be some relatively simple SQL solution for this. Despite my efforts, I have been unable to come up with a query (or set of queries) to do exactly what I want.
The basic data input/output would be as follows.
(No duplicate combinations.)
I imagine that This should be able to be accomplished using some NOT IN or NOT LIKE subqueries, but I haven't been able to come up with a solution.
Does anybody have any ideas?
