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. Both the INSERT statements would fail because all constraints are automatically retrieved when the table is flashed back.
B. Both the INSERT statements would succeed because none of the constraints on the table are automatically retrieved when the table is flashed back.
C. 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.
D. 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.

QUESTION 80
Evaluate the following CREATE TABLE command:
CREATE TABLE order_item (order_id NUMBER(3),
Item_id NUMBER(2),
qty NUMBER(4),
CONSTRAINT ord_itm_id_pk
PRIMARY KEY (order_id jtem_id)
USING INDEX
(CREATE INDEX ord_itm_idx
ON order_item(order_id item_id)));
Which statement is true regarding the above SOL statement?
A. It would execute successfully and only ORD_ITM_IDX index would be created.
B. It would give an error because the USING INDEX clause cannot be used on a composite primary key.
C. It would execute successfully and two indexes ORD_ITM_IDX and ORD_ITM_ID_PK would be created.
D. It would give an error because the USING INDEX clause is not permitted in the CREATE TABLE command.
