I have 2 tables with my products. My products are defined by 3 barcodes, and i would link them by using these codes.
The problem is that some codes are missing. For example, i have a product with cip7 and cip13 in my first table and on cip7 in my second table.
How can i link my 2 tables to link my product if there is at least one code in common ?
Thanks for your help !
