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.
This is a part of the course
“Building and Optimizing Triggers in SQL Server”
Exercise instructions
- Create the new trigger for the
Orders
table. - Set the trigger to be fired only after
UPDATE
statements.
