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：因为日期的默认格式是 dd-mon-yy，所以 January 1, 2000 转换成匹配的格式为

01-jan-00

)
