Practicing creating triggers

The Fresh Fruit Delivery company needs help creating a new trigger called OrdersUpdatedRows on the Orders table.

This trigger will be responsible for filling in a historical table (OrdersUpdate) where information about the updated rows is kept.

A historical table is often used in practice to store information that has been altered in the original table. In this example, changes to orders will be saved into OrdersUpdate to be used by the company for auditing purposes.
