we have a website that has many products on the website. we have given each product a sku number. let's say the number we gave was 12-1 for a jewelry item. when we look at the data base, it appears as 12-1. we downloaded the database and made several changes to the prices of each item. when we uploaded the csv file back to the database, the 12-1 sku number came out as a date number. instead of trying to fix all the numbers, can we revert back to lets say 12-30-09 restore? that way all the numbers would be the same before we started to work on the database. thanks again.
