I have a join table of skus which encompasses items which have different attributes(sizes).
When assigning a new attribute from a join table, I would like a script to check if attribute already exist in the other table and ignore or copy the attributeid and parentid into other table. For example I might have 10 items with attribute MD, but I only want to copy that MD once. This way I can have another table of measurements that is tied to the Parent Table.
Hope that makes sense.
