mysql的一个报错,求解决
Centos 7.5 系统安装的<em>mysql</em>数据库,设置了密码。rn<em>mysql</em> -uroot -p 密码 进入后,使用sql语句报下面的错误:rnrnERROR 1820 (HY000) You must reset your password using ALTER USER statement before executing this statement;rnrn按照网上的操作方式,不管输入任何语句都会报上面的错误,所以无法<em>解决</em>问题,求大家帮助看看,如何<em>解决</em>。rnrn我初步的<em>解决</em>方式是:rn修改了配置文件 my.cnf 在[<em>mysql</em>d]下面输入了 skip-grant-tables 然后重启<em>mysql</em>d服务,再次无密码认证进入数据库后就可以正常使用<em>mysql</em>语句,去掉my.cnf文件中的这句话就不可以了。。。。。
MySQL建表报错!Row size too large!
Hibernate在MySQL自动建表时报了以下错误~ rnrnERROR org.hibernate.<em>too</em>l.hbm2ddl.SchemaUpdate - Unsuccessful: create table Advert (id bigint not null auto_increment, space varchar(255), administrators varchar(4000), readers varchar(4000), editors varchar(4000), creator varchar(255), salesman varchar(255), spaceSize varchar(255), advertType varchar(255), createDate varchar(255), contactName varchar(255), receivableDate varchar(255), money varchar(255), publishTime varchar(255), advertName varchar(255), salesmanId varchar(255), newsSerialNumber varchar(255), advertDate varchar(255), draftDate varchar(255), spaceEdit varchar(255), newsAdd varchar(255), drafter varchar(255), advertContent varchar(1300), remack varchar(4000), contract_id bigint, customer_id bigint, primary key (id)) rnrnERROR org.hibernate.<em>too</em>l.hbm2ddl.SchemaUpdate - Row size <em>too</em> large. The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs rnrn自己算了一下,这张表怎么都还没到65535啊~ rnrn后来上网找了一下,发现UTF-8编码的,一个字符当3个算~郁闷~ rnrn然后自己算了一下,确实超过了,然后减少了其中一个varchar,表就建起来了~ rnrn再后来上官网看到好像是InnoDB限制了,但它又没说怎么去改(最主要是我不知道InnoDB是什么……)! rnrn所以想请教一下大家,是否有办法改一下什么配置能让它把表建起来~谢谢~ rn
