1.创建表格

reate table trade(
		id int(4) not null primary key auto_increment,
		product varchar(30) null,
		price decimal(10,2),
		create_time timestamp
	)ENGINE=InnoDB DEFAULT CHARSET=utf8;;

2.单条插入

NSERT INTO trade
	(product, price, create_time)
	VALUES
	("毛巾", 105, '2018-04-5 23:38:19');

INSERT INTO trade
	 (product, price, create_time)
	 VALUES
	 ("枕头", 2, '2018-04-07 23:37:38');

3.多条插入

NSERT INTO trade
	(product, price, create_time)
	VALUES
	("显示器", 500, '2018-05-07 23:37:25'),
	("CPU", 200, '2018-06-07 23:37:38'),
	("硬盘", 300, '2018-07-06 23:38:02'),
	("内存", 400, '2018-08-5 23:38:19');
