This question is from my database class;

using SQL

In this part we create a small procedure:

Write a procedure that has as input the customer_id. Then the procedure should delete the corresponding customer from table customers.

Notice that customer_id is a foreign key on table orders. Therefore the customer cannot be deleted if he has placed orders. To delete a record from customers you should first delete the corresponding orders and to do that you need to first delete the corresponding order_details.

Now execute the procedure to delete customer with id 1. If you have solved part 01 a record will be inserted into Customer_Archives.

ROLLBACK; and all these changes will be undone!
