Offices Table

1. Create a trigger that will allow you to check the value of the country column before any insert action to the offices table, so that:

country can only be USA, France, Japan, UK, and Australia

If the value to be inserted to the country column is outside of the listed values, we assign the country column of the record to NULL.

Customers Table

Orders Table

2. Create a procedure and call it CustomerTotal

Making the procedure will allow you to get the total number of orders made by each customer, along with customer's first and last name, and country.
