I have a table of products called 'products' like:
| id | name | desc | price | supplierId | barcode1 | barcode2 | barcode3 | barcode4 | etc.........
Some products have as many as 10 different barcodes. Obviously this is a ridiculous setup of barcodes (imported from supplier price lists) which I would like send to their own table called 'barcodes' like:
| productId | barcode |
(where productId is matched to that in the 'products' table - products.id)
Then each barcode can be slit into their own entries.
Thing is I have thousands of products. Any idea on how I can do this in bulk? I don't really know where to start!
