If I have a Customers table linked to an Orders table, and I want to delete a customer and its corresponding orders, then I can do:

dataContext.Orders.DeleteAllOnSubmit(customer.Orders);
dataContext.Customers.DeleteOnSubmit(customer);

...which is great. However, what if I also have an OrderItems table, and I want to delete the order items for each of the orders deleted?

I can see how I could use DeleteAllOnSubmit to cause the deletion of all the order items for a single order, but how can I do it for all the orders?
