View the Exhibit and examine the descriptions for ORDERS and ORDER_ITEMS tables.
Evaluate the following SQL statement:
SELECT o.customer_id, oi.product_id, SUM(oi.unit_price*oi.quantity) “Order Amount” FROM order_items oi JOIN orders o
ON oi.order_id = o.order_id
GROUP BY CUBE (o.customer_id, oi.product_id);
Which three statements are true regarding the output of this SQL statement? (Choose three.)
A.
It would return the subtotals for the Order Amount of every CUSTOMER_ID. B. It would return the subtotals for the Order Amount for every PRODUCT_ID.
B.
It would return the subtotals for the Order Amount of every PRODUCT_ID and CUSTOMER_ID as one group.
C.
It would return the subtotals for the Order Amount of every CUSTOMER_ID and PRODUCT_ID as one group.
D.
It would return only the grand total for the Order Amount of every CUSTOMER_ID and PRODUCT_ID as one group.
A, B, C are correct.
D is not correct. ‘It would return ONLY the grand total’ NOT TRUE!
SELECT deptno,job, count(job)
FROM emp
GROUP BY cube( deptno, job);
yeh…A,B,C are correct
I think Options are like this:
A.It would return the subtotals for the Order Amount of every CUSTOMER_ID.
B. It would return the subtotals for the Order Amount for every PRODUCT_ID.
C.It would return the subtotals for the Order Amount of every PRODUCT_ID and CUSTOMER_ID as one group.
D.It would return the subtotals for the Order Amount of every CUSTOMER_ID and PRODUCT_ID as one group.
E.It would return only the grand total for the Order Amount of every CUSTOMER_ID and PRODUCT_ID as one group.
