Triggers vs. stored procedures

One important task when you take ownership of an existing database is to familiarize yourself with the objects that comprise the database.

This task includes getting to know existing procedures, functions, and triggers.

You find the following objects in the Fresh Fruit Delivery database:

The company uses a regular stored procedure, MonthlyOrders, for reporting purposes. The stored procedure sums up order amounts for each product every month.
The trigger CustomerDiscountHistory is used to keep a history of the changes that occur in the Discounts table. The trigger is fired when updates are made to the Discounts table, and it stores the old and new values from the Discount column into the table DiscountsHistory.
