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_…

异常介绍: ONLY_FULL_GROUP_BY 指的是你查询的语句使用到了group by 例如  select name,age from person group by sex; 此时你group by 的是性别但是查询的是name,age在mysql5.7中不是合法的 正确写法的是  select sex from person group by sex; 但是如果你坚持那样写的话,可以采用下面方法解决 找到你的mysqld.cnf文件,将红框中的字段去掉后,重启mysql解决问题…

MySQL5.7后将sql_mode的ONLY_FULL_GROUP_BY模式默认设置为打开状态,这样一来,很多之前的sql语句可能会出现错误,错误信息如下: Error Code: 1055. Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column '×××' which is not functionally dependent on columns in GROUP B…

近期在开发过程中,因为项目开发环境连接的mysql数据库是阿里云的数据库,而阿里云的数据库版本是5.6的.而测试环境的mysql是自己安装的5.7.因此在开发过程中有小伙伴不注意写了有关group by的sql语句.在开发环境中运行是正常的,而到了测试环境中就发现了异常. 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. 其中ONLY_FULL_GROUP_BY就是造成这个错误的罪魁祸首了,对于group by聚合…

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…

一.出错原因 最近因为开发数据库与部署数据库版本不同,带来了几个问题,其中only_full_group_by问题是之前没有遇到的. 具体报错如下 [Err] 1055 - Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'information_schema.PROFILING.SEQ' which is not functionally dependent…

数据库版本是5.7.19,在写语句的时候,只要涉及ORDER BY,就会报错, ERROR 1055 (42000): Expression #7 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'postscan.verifyDelayLog.auditor' which is not functionally dependent on columns in GROUP BY clause;…
