Mysql创建表实现主键自增并且初始值为1000

CREATE TABLE `seckill` (
`seckill_id` bigint(20) NOT NULL AUTO_INCREMENT comment '商品库存id' ,
`name` varchar(120) NOT NULL comment '商品名称' ,
`number` int(11) 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 on update 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 DEFAULT CHARSET=utf8 AUTO_INCREMENT=1000 comment '秒杀库存表';
