摘要:属性是在数据库,表中,点进去,可以看到默认属性是解决这个问题,就需要修改这个字段的属性。方法二修改配置的文件在安装这个版本的的时候,我没有发现的配置文件。
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; this is incompatible with sql_mode=only_full_group_by
这个时候,百度发现,是因为这个版本的mysql 数据库默认开启了 sql_mode 字段的only_full_group_by 属性。这个属性是在你写语句时,当你 ORDER BY 的字段不在select 的字段当中,都会报错。
sql_mode 属性是在mysql数据库,event表中,
点进去,可以看到默认属性是
ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
解决这个问题,就需要修改这个字段的属性。
方法一
在navicat 里面直接针对event表进行修改
set GLOBAL sql_mode ="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION ";
这样就能去掉only_full_group_by 字段。但弊端是这个方法是针对session的,也就是说每次连接mysql 前,都需要set一次。
方法二
修改配置mysql的文件
mac在安装这个版本的mysql的时候,我没有发现mysql 的配置文件。不管是
/etc 下还是 mysql 的support-files 下都没有
这个时候,可以自己在etc目录下创建一个
关闭mysql
sudo vim /etc/my.cnf
然后往文件里写这个配置就ok。
