Mysql创建表实现主键自增并且初始值为1000

具体sql语句为如下：

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';
