071考試-第20題、choose the best answer
View the Exhibit and examine the data in the PROMOTIONS table.
PROMO_BEGIN_DATE is stored in the default date format, dd-mon-rr.
You need to produce a report that provides the name,cost,and start date of all promos
in the POST category that were launched before January 1, 2000.
Which SQL statement would you use?
A) SELECT promo_name, promo_cost, promo_begin_date
FROM promotions
WHERE promo_category LIKE '%post%' AND promo_begin_date < '1-JAN-00';
B) SELECT promo_name, promo_cost, promo_begin_date
FROM promotions
WHERE promo_category = 'post' AND promo_begin_date < '01-01-00';
C) SELECT promo_name, promo_cost, promo_begin_date
FROM promotions
WHERE promo_cost LIKE 'post%' AND promo_begin_date < '01-01-2000';
D) SELECT promo_name, promo_cost, Promo_begin_date
FROM promotions
WHERE promo_category LIKE 'p%' AND promo_begin_date < '1-JANUARY-00';
Answer：A
(解析：因為日期的默認格式是 dd-mon-yy，所以 January 1, 2000 轉換成匹配的格式為 01-jan-00
)
