How can i import customerid into orders table when orders are made

Question

Im building relation database

Answer 1

Your question is not clear and you used your code snippet as keywords. Normally you should know the customerId within the context you're trying to do something for a customer (like inserting a new order record into the orders table). If not and you have another customer-specific property available, you might look the Id up. If you don't have anything, then there went something terribly wrong within your application's design.
