There is a simple view SCOTT.DEPT_VIEW on the table SCOTT.DEPT.

This insert fails with an error:

ERROR at line 1:

ORA-01400: cannot insert NULL into ("SCOTT"."DEPT"."DEPTNO")

What might be the problem?

AThe INSERT violates a constraint on the detail table.

BThe INSERT violates a constraint on the view.

CThe view was created as WITH READ ONLY.

DThe view was created as WITH CHECK OPTION.

Show Suggested Answer

Suggested Answer: A

B is incorrect because constraints are enforced on detail tables, not on views. C and D are incorrect because the error message would be different.
