I need some advice of how to setup my tables I currently have a product table and a product codes table.
In the codes table I have an id and a title such as:
1 567902
2 345789
3 345678
there can be many items in this table.
In my product table I have the usual product id,title, etc but also a code id column that I'm currently storing a comma separate list of ids for any codes the product needs to reference.
in that column I could end up with ids like: 2,5,6,9
I'm going to need to be able to search the products table looking for code ids for a specific set this is where I've come into problems trying to use id IN ($var) or FIND_IN_SET is proving problematic I've been advised to restructure it I'm happy to do just wondering what the best method would be.
