Creating your first trigger

You have been hired by the company Fresh Fruit Delivery to help secure their database and ensure data integrity. The company sells fresh fruit to other online shops, and they use several tables to keep track of stock and placed orders.

One of their tables (Discounts) specifies the discount amount that shops receive when placing large orders. A deletion of several hundred rows happened at some point in the past when one of their employees removed some orders by mistake. They need a new trigger on the Discounts table to prevent DELETE statements related to the table, and this is where you can help.
