NEW QUESTION # 316
Which three statements are true about performing Data Manipulation Language (DML) operations on a view In an Oracle Database?

A. Insert statements can always be done on a table through a view.
B. The WITH CHECK clause has no effect when deleting rows from the underlying table through the view.
C. Views cannot be used to add or modify rows in an underlying table if the defining query of the view contains the DISTINCT keyword.
D. Views cannot be used to add on modify rows in an underlying table if the defining query of the view contains aggregating functions.
E. Views cannot be used to add rows to an underlying table if the table has columns with NOT NULL constraints lacking default values which are not referenced in the defining query of the view.
F. Views cannot be used to query rows from an underlying table if the table has a PRIPOARY KEY and the PRIMARY KEY columns are not referenced in the defining query of the view.

Answer: C,D,E

Explanation:
When performing DML operations on a view, certain restrictions apply:
* D. Views cannot be used to add or modify rows in an underlying table if the defining query of the view contains the DISTINCT keyword: If the defining query of a view contains the DISTINCT keyword, it cannot be used for certain DML operations, such as INSERT and UPDATE, because the set of rows it represents is not directly modifiable.
* E. Views cannot be used to add or modify rows in an underlying table if the defining query of the
* view contains aggregating functions: Aggregating functions create a result that summarises multiple rows and cannot be reversed to point to a single row for modification.
* F. Views cannot be used to add rows to an underlying table if the table has columns with NOT NULL constraints lacking default values which are not referenced in the defining query of the view: If a column with a NOT NULL constraint is not included in the view's defining query, and it does not have a default value, it is not possible to insert through the view because it would violate the NOT NULL constraint.
References:
* Oracle Database SQL Language Reference 12c, particularly the sections on views and the restrictions on DML operations through views.
