Evaluate the following query:

SELECT INTERVAL '300' MONTH,

INTERVAL '54-2' YEAR TO MONTH,

INTERVAL '11:12:10.1234567' HOUR TO SECOND

FROM dual;

What is the correct output of the above query?

A) +25-00 , +00-650, +00 11:12:10.123457

B) +25-00 , +54-02, +00 11:12:10.123457

C) +00-300, +00-650, +00 11:12:10.123457

D) +00-300, +54-02, +00 11:12:10.123457

Answer:B

(解析:

INTERVAL '300' MONTH:300 个月为+25-00(25 年,即 25*12+0)

INTERVAL '54-2' YEAR TO MONTH:+54-02,表示 54 年零 2 个月

INTERVAL '11:12:10.1234567' HOUR TO SECOND: +00 11:12:10.123457(+00 表示 0 天),表示 11 个小时,12 分,10.123457 秒
