question about orders_id table
We've arranged a special "import order" system to move orders from a business customer's site (using osCommerce) to our Zen site. It seems to work fine -- importing just 3 tables: orders, orders_products, orders_total.
The one problem I've discovered is the orders_id table - osCommerce doesn't seem to have it, so we need to make sure we add the orders_ids coming from him into this table, so the next order from another customer will be incremented correctly. I was planning on just manually adding the order numbers to the orders_id table -- but what about that session_id variable?
Does it matter if I just leave it blank? Does it need to match with something else?
And does anybody know of any other tables that we're missing like orders_id, that might cause problems? Thanks a lot!
Currently using ZEN CART v. 1.3.6
