There are three tables – table specific to item, table specific to distributor and a join table that has existing combination of item and distributor. Usually use fill in the jon table to with the possible (existing combination of item and the distributor level where they are sold. I need a union query oof some sort that returns a Cartesian product of the two tables – items Distributor join table and distributor List table - so that for example –
If item T23 was listed with only distributor D01 in the join table >> then the query returns a total of 5 rows – with the possible combination of that item and all the other distributor list but puts 0 for the price. See attached image and DB.
