Which three statements are true about performing DML operations on a view with no INSTEAD...

A: Insert statements can be done through a view only if all NOT NULL constraints without default values of the base table are included in the view. Therefore, statement A is incorrect.

B: The WITH CHECK OPTION ensures that all DML operations performed through the view result in data that conforms to the view’s defining query. It affects DELETE as well as other DML operations, making statement B incorrect.

C: Similar to inserts, DELETE operations can be done through a view unless the view contains constructs that inherently do not support it, such as certain joins or set operations. Statement C is generally incorrect.

D: If a view does not include all NOT NULL columns without defaults of the underlying table, it cannot be used to add rows because the missing columns will lack values. This makes statement D correct.

E: This statement is incorrect as primary keys do not affect querying through views; they affect insert and update operations where uniqueness and non-nullability are enforced.

F: If the defining query of a view includes DISTINCT, the view generally cannot be used to perform update or insert operations as it may not be able to uniquely determine rows. This makes statement F correct.
