Lol, I know I have done this twice in my life. 1st time was on the dev box on a restore of production, so I could simply run a update query reading the correct values from the production database. Second time was a week or 2 ago on a system i developed freelance. There was no source, and no backups as yet. It was an update of the product code of only (well suposed to be...) two products. Lucky for me the product code is based on the primary key, the store branch, and category. So I just ran a update query to reconstruct the original product item no.

This solution might not be elegant, but will save paper in the sense of less written warning will be be issued to slightly careless developers/dba's

From my side, Thank you.
