Q57. View the Exhibit and examine the structure of the ORDERS table.
The columns ORDER_MODE and ORDER TOTAL have the default values'direct “and respectively.
Which two INSERT statements are valid? (Choose two.)

INSERT INTO (SELECT order_id, order date, customer_id FROM orders) VALUES (1,
’09-mar-2007″101);

INSERT INTO orders (order_id, order_date, order mode,customer_id, order_total) VALUES (1, TO_DATE (NULL),’online’,101, NULL) ;

INSERT INTO orders VALUES (1, ’09-mar-2007′, ‘online’,’ ‘,1000);

INSERT INTO orders VALUES(’09-mar-2007’DEFAULT,101, DEFALLT);

Q58. View the Exhibit and examine the structure of the ORDERS table. The ORDER_ID column is the PRIMARY KEY in the ORDERS table.

Evaluate the following CREATE TABLE command:
CREATE TABLE new_orders(ord_id, ord_date DEFAULT SYSDATE, cus_id)
AS
SELECT order_id.order_date,customer_id
FROM orders;
Which statement is true regarding the above command?

The NEW_ODRDERS table would not get created because the DEFAULT value cannot be specified in the column definition.

The NEW_ODRDERS table would get created and only the NOT NULL constraint defined on the specified columns would be passed to the new table.

The NEW_ODRDERS table would not get created because the column names in the CREATE TABLE command and the SELECT clause do not match.

The NEW_ODRDERS table would get created and all the constraints defined on the specified columns in the ORDERS table would be passed to the new table.
