你想生成一个显示po_id和罚款金额的报表, 如果SHIPMENT_DATE 晚于PO_DTAE一个月,那么将会产生罚款,罚款金额为每天$20.

SQL> SELECT po_id, CASE
WHEN MONTHS_BETWEEN (shipment_date,po_date)>1 THEN
TO_CHAR((shipment_date - po_date) * 20) ELSE 'No Penalty' END PENALTY FROM shipments;

SQL>SELECT po_id, DECODE (MONTHS_BETWEEN (po_date,shipment_date)>1, TO_CHAR((shipment_date - po_date) * 20), 'No Penalty') PENALTY FROM shipments;

Which statement is true regarding the above commands?
A. Both execute successfully and give correct results.
B. Only the first query executes successfully but gives a wrong result.
C. Only the first query executes successfully and gives the correct result.
D. Only the second query executes successfully but gives a wrong result.
