* ERROR at line 1:
ORA-01400: cannot insert NULL into ("SCOTT"."DEPT"."DEPTNO")
What might be the problem?
This insert fails with an error:
SQL> insert into dept_view values('SUPPORT','OXFORD'); insert into dept_view values('SUPPORT','OXFORD')
* ERROR at line 1:
ORA-01400: cannot insert NULL into ("SCOTT"."DEPT"."DEPTNO")
What might be the problem?
Correct 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.
