在安装有些二开框架时会遇到下面的问题,在填写完数据库密码之后他会提示你请在mysql配置文件中修改ql-mode去掉ONLY_FULL_GROUP_BY,但是我们去mysql的配置文件中查找此配置,有时候会发现压根就没有这个配置,这时候我们就要拿出杀手锏 cmd 来帮助我们完成这项使命了 first:win+r 输入 cmd,来到安装mysql的根目录,使用phpstudy的小伙伴可以到 phpstudy\PHPTutorial\MySQL\bin 这个目录下按住shift然后按住鼠标右键然后选…

ONLY_FULL_GROUP_BY是mysql默认的一种sql模式,其作用是约束sql语句:要求select中的所有字段,除复合函数外,全部要出现在group by中. 默认这种模式是有原因的,因为滥用gourp by可能会得到错误的结果,但是这里不做讨论.那么如何禁用这种模式呢,执行以下命令: $ # 查看sql_mode配置$ mysql> select @@sql_mode 要想永久禁用,将sql_mode写入 /etc/mysql/mysql.conf.d  下的 mysqld.cnf…

下载安装的是最新版的mysql5.7.x版本,默认是开启了 only_full_group_by 模式的,但开启这个模式后,原先的 group by 语句就报错,然后又把它移除了. 一旦开启 only_full_group_by ,感觉,group by 将变成和 distinct 一样,只能获取受到其影响的字段信息,无法和其他未受其影响的字段共存,这样,group by 的功能将变得十分狭窄了 only_full_group_by 模式开启比较好. 因为在 mysql 中有一个函数: any_…

原因分析:MySQL5.7版本默认设置了 mysql sql_mode = only_full_group_by 属性,导致报错. 1.查看sql_mode SELECT @@sql_mode; 2.去掉ONLY_FULL_GROUP_BY,重新设置值. SET @@global.sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO…
