View the Exhibit and examine the data in ORDERS and ORDER_ITEMS tables. You need
to create a view that displays the ORDER ID, ORDER_DATE, and the total number of items
in each order. Which CREATE VIEW statement would create the view successfully?
A.
CREATE OR REPLACE VIEW ord_vu (order_id,order_date) AS SELECT o.order_id,
o.order_date, COUNT(i.line_item_id) “NO OF ITEMS” FROM orders o JOIN order_items i
ON (o.order_id = i.order_id) GROUP BY o.order_id,o.order_date;
B.
CREATE OR REPLACE VIEW ord_vu AS SELECT o.order_id, o.order_date,
COUNT(i.line_item_id) “NO OF ITEMS” FROM orders o JOIN order_items i ON (o.order_id
= i.order_id) GROUP BY o.order_id,o.order_date;
C.
CREATE OR REPLACE VIEW ord_vu AS SELECT o.order_id, o.order_date,
COUNT(i.line_item_id) FROM orders o JOIN order_items i ON (o.order_id = i.order_id)
GROUP BY o.order_id,o.order_date;
D.
CREATE OR REPLACE VIEW ord_vu AS SELECT o.order_id, o.order_date,
COUNT(i.line_item_id)ll’ NO OF ITEMS’ FROM orders o JOIN order_items i ON (o.order_id
= i.order_id) GROUP BY o.order_id,o.order_date WITH CHECK OPTION;
