Windows端 MySQL5.7版本的 only_full_group_by 1055 解决方案

MySQL5.7版本的 only_full_group_by 1055 解决方案

方案一：只修改当前数据库的SQL_MODE

-- 查询版本

SELECT VERSION();

SELECT @@GLOBAL.sql_mode;

SELECT @@SESSION.sql_mode;

 
-- 注意：重新 SET 的内容是将原来内容里的 "only_full_group_by" 删除后的剩下部分

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';
 
SET SESSION sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

方案二：修改全局配置文件my.ini

-- 查看数据库的存储地址

SELECT @@datadir

-- 结果如下
-- D:\Program Files\mysql-5.7.17-winx64\data\

1.查看数据库的存储地址：

2.打开对应的地址 配置文件路径 D:\Program Files\mysql-5.7.17-winx64，找到 my.ini (如果只有 my-default.ini ，而没有 my.ini ，复制 my-default.ini 重命名为 my.ini 即可)

3.把最后一行原来的的 sql_mode 注释掉，添加如下代码

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

4.----------------修改后的 my.ini 配置如下-------------------

# Remove leading # to set options mainly useful for reporting servers.

#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
