Yep - not my design.

Can you do it in a couple of steps, inner join on the 2 layouts and eliminate them from the process,


I suspect that join between the two tables will return on the order of a billion rows. Either because there are very few rows that are not matched or there are zero. I am only expecting the first because with legacy data orphans might occur.

possibly even move the non matching records


I have to find them first. Once I find them I don't consider the analysis to be a problem. Actually for those that do not match I consider it likely they are orphans.
