I’ve never used “ORDER BY …..” in any of my queries. If you want to get the records in order by id, you would simply do “ORDER BY id”. If you want them by product it would be “ORDER BY product_id”.
Your best bet (depending on what you want) is likely “ORDER BY product_id, id” which will give you the records in order by product id and then if you have multiple records with the same product_id, it will also order by id. So your results would look like:
id product_id
12...............3....................................
10...............4................................
25...............4.................................
33...............6...................................
40...............6..................................
43...............7...................................
17...............10.................................
