CREATE TABLE new_sales (prod_id, cust_id, order_date DEFAULT SYSDATE)
AS

You execute these commands:
CREATE TABLE customers (customer id INTEGER, customer name VARCHAR2 (20));
INSERT INTO customers VALUES (1,'Custmoer1 ');

INSERT INTO customers VALUES (2, 'Customer2 ');
<TODO>
SELECTCOUNT (*) FROM customers;
Which two, used independently, can replace <TODO> so the query retums 1?

Evaluate the following two queries:

Which statement is true regarding the above two queries?

Examine this partial query:
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 (&apos;Direct Sales&apos;, &apos;Internet&apos;)
AND t.month IN (&apos;2000-09&apos;, &apos;2000-10&apos;)
AND co.country code IN (&apos;GB&apos;, &apos;US&apos;)
Examine this output:

Which GROUP BY clause must be added so the query returns the results shown?
