sql怎么添加语句

三、新建一个SQL,创建一个表

use demo;

create table seckill (

seckill_id bigint NOT NULL AUTO_INCREMENT COMMENT '商品库存id',

name varchar(120) NOT NULL COMMENT '商品名称',

number int NOT NULL COMMENT '库存数量',

start_time timestamp NOT NULL COMMENT '秒杀开启时间',

end_time timestamp NOT NULL COMMENT '秒杀结束时间',

create_time timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',

PRIMARY KEY (seckill_id),

key idx_start_time(start_time),

key idx_end_time(end_time),

key idx_create_time(create_time)

)ENGINE=InnoDB AUTO_INCREMENT=1000 DEFAULT CHARSET=utf8 COMMENT='秒杀库存表';

然后继续添加数据：

insert into

seckill(name,number,start_time,end_time)

values

('100秒杀iphone9',100,'2018-8-1 00:00:00','2018-9-1 00:00:00'),

('200秒杀iPad',200,'2018-8-1 00:00:00','2018-11-1 00:00:00'),

('300秒杀小米8',300,'2018-8-1 00:00:00','2018-11-1 00:00:00'),

('400秒杀小米笔记本电脑',400,'2018-8-1 00:00:00','2018-11-11 00:00:00');

四、继续键入查询：

select * from seckill;

选中运行，输出添加结果，如图所示：
