Use caution when granting the privilege to insert data using a view because data in fields not visible to the user may be inserted when a row is inserted using a view.
The following rules apply to inserting rows using a view:
- Both you and the immediate owner of the view must have the appropriate privileges.
- The view must reference columns in only one table or view.
- None of the columns in the view can be derived by using an expression to change values in the underlying table.
- Each column in the view must correspond one to one with a column in the underlying table or view.
- The view must include any column in the underlying table or view that is declared as NOT NULL.
- No two view columns can reference the same column in the underlying table.
- If the request used to define a view contains a WHERE clause, and WITH CHECK OPTION, all values inserted using that view must satisfy constraints specified in the WHERE clause.
If a view includes a WHERE clause but does not include the WITH CHECK OPTION, then data can be inserted that is not visible using that view.
