Best way to save a ordered List to the Database while keeping the ordering

Question

I was wondering if anyone has a good solution to a problem I\'ve encountered numerous times during the last years.

I have a shopping cart and my customer explicitly

Answer 1

I would recommend keeping gaps in the order number, so instead of 1,2,3 etc, use 10,20,30... If you need to just insert one more item, you could put it at 15, rather than reordering everything at that point.
