NEW QUESTION # 242

SELECT ch.channel_type, t.month, co.country_code, SUM(s.amount_sold) SALES FROM sales s, times t, channels ch, countries co WHERE s.time_ id = t.time id AND s.country_ id = co. country id AND s. channel id = ch.channel id AND ch.channel type IN ('Direct Sales', 'Internet') AND t.month IN ('2000-09', '2000-10') AND co.country code IN ('GB', 'US') Examine this output:

D specifies a ROLLUP on country_code only, which would not correctly group by channel_type and month.
