071考试题库-第41题、choose two

View the Exhibit and examine the structure of the ORDERS table.

The columns ORDER_MODE and ORDER_TOTAL have the default values 'direct' and 0 respectively.

Which two INSERT statements are valid? (Choose two.)


A) INSERT INTO

(SELECT order_id,order_date,customer_id FROM orders)

VALUES (1,'09-mar-2007', 101);


B) INSERT INTO orders

(order_id,order_date,order_mode,

customer_id,order_total)

VALUES(1,TO_DATE(NULL), 'online', 101, NULL);


C) INSERT INTO orders

VALUES (1, '09-mar-2007', 'online','',1000);


D) INSERT INTO orders

(order_id,order_date,order_mode,order_total)

VALUES (1,'10-mar-2007','online',1000);


E) INSERT INTO orders

VALUES (1,'09-mar-2007', DEFAULT, 101, DEFAULT);


Answer:AE

(解析:验证过,考点是考如何插入默认值的列,实际插入过程中可以忽略列,或者用 default 关键字显示

插入。D 语法没有错误,但是 customer_id 是非空约束,所以无法插入)
