Oracle Database SQL Expert Sample Questions:
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 succeed because none of the constraints on the table are automatically retrieved when the table is flashed back.
- B. 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.
- C. Both the INSERT statements would fail because all constraints are automatically retrieved when the 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.

value as SYSDATE.
Evaluate the following statement:
UPDATE orders
SET order_date=DEFAULT
WHERE order_id IN (SELECT order_id FROM order_items
WHERE qty IS NULL);
What would be the outcome of the above statement?
- A. The UPDATE statement would change all ORDER_DATE values to SYSDATE provided the current ORDER_DATE is NOT NULL and QTY is NULL
- B. The UPDATE statement would not work because the main query and the subquery use different tables.
- C. The UPDATE statement would change all the ORDER_DATE values to SYSDATE irrespective of what the current ORDER_DATE value is for all orders where QTY is NULL
- D. The UPDATE statement would not work because the DEFAULT value can be used only in INSERT statements.
