View the Exhibit and examine the data in EMP and DEPT tables. In the DEPT table,
DEPTNO is the PRIMARY KEY. In the EMP table, EMPNO is the PRIMARY KEY and
DEPTNO is the FOREIGN KEY referencing the DEPTNO column in the DEPT table. What
would be the outcome of the following statements executed in the given sequence? DROP
TABLE emp; FLASHBACK TABLE emp TO BEFORE DROP; INSERT INTO emp VALUES
(2,COTT 10); INSERT INTO emp VALUES (3,ING 55);
A.
Only the second INSERT statement would succeed because all the constraints except
referential integrity constraints that reference other tables are retrieved automatically after
the table is flashed back.
B.
Both the INSERT statements would fail because all constraints are automatically
retrieved when the table is flashed back.
C.
Both the INSERT statements would succeed because none of the constraints on the
table are automatically retrieved when the table is flashed back.
D.
Only the first INSERT statement would succeed because all the constraints except the
primary key constraint are automatically retrieved after a table is flashed back.
