Creating the PreventNewDiscounts trigger
The company doesn't want regular users to add discounts. Only the Sales Manager should be able to do that.
To prevent such changes, you need to create a new trigger called PreventNewDiscounts.
The trigger should be attached to the Discounts table and prevent new rows from being added to the table.
