Chapter 11: Views: Limiting Access to Data

Views created using with check option

This restriction determines what types of modifications you can make through views with check options. If a view has a with check option clause, each row inserted or updated through the view must be visible within the view. This is true whether you insert or update the view directly or indirectly, through another derived view.
