Write a script that creates and calls a stored procedure named test. This procedure should use a transaction that includes the statements necessary to combine two customers. These statements should do the following: Select a row from the Customers table for the customer with a customer_id value of 6. This statement should lock the row so other transactions can’t read or modify it until the transaction commits, and it should fail immediately if the row is locked from another session. Update the Orders table so any orders for the selected customer are assigned to the customer with a customer_id value of 3. Update the Addresses table so any addresses for the selected customer are assigned to the customer with a customer_id value of 3. Delete the selected customer from the Customers table. If these statements execute successfully, commit the changes. Otherwise, rollback the changes.
