(1)MySQL数据库设置自增序号,删除表中数据序号错乱重新排序

alter table tablename drop column id;
alter table tablename add id mediumint(8) not null primary key auto_increment first;

alter table tablename auto_increment=0

(2)执行创建表的sql语句设置默认编码格式

CREATE TABLE `school` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(64) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL,
  `actTime` datetime NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

CHARACTER SET utf8 COLLATE utf8_unicode_ci

设置默认编码UTF-8,不区分大小写ci不区分大小写,cs区分大小写
