Hi all
I am trying to do some Multi Product Affinity analysis. Database is sql 2008. The Business Question is
When customers purchased product A and Product B in one transaction, what other product/s did they purchase in the same transaction. See the sample data below. In this example , if I choose product '2008' and '2009' then the output expected is
Associated_Product qty
2006 1
Thank you
