Correct Order Status on multiple orders

Somehow a batch of old orders, about 500 of them, that were status: shipped got changed to status: prosessing. What is the best way to go about moving them back to shipped? Would I use a sql statement? or open the database and manually change it in the table where it resides? Any other ideas?

Hi there
It would be easiest using a sql statement. However there would need to be something common for all orders to make this work. Eg you could use the date. The satement based on date would be:
update zen_orders set orders_status = 3 WHERE zen_orders.date_purchased >= '2007-01-15' and zen_orders.date_purchased <= '2007-01-21'
You would need to change dates as per you range and if you don't use the 'zen_" prefix in your database you would also remove the prefix from above statement.
