I have a main table that contains barcode numbers. I then have a related table containing the information related to the barcode record. However one of the fields in the second table has a field which says this record is related to two/three other barcodes. It does not state the Barcodes its related to, so I am trying to do a manual link of barcode numbers this record is related to. Unfortunately the database already contains data, so if a junction table is to be used then I'm not sure how I proceed. I am trying to end up with the user clicking on any barcode and it also showing others that might be related. Hope I have explained it clearly, thanks.
