Mysql8 group by 报错 Cause: java.sql.SQLSyntaxErrorException: Expression #1 of SELECT list is not in GROUP BY

本文转载自  查看原文  2021-11-02 09:08  1330    坑

原因: myql8开启了ONLY_FULL_GROUP_BY

1. select @global.sql_mode  有值说明开启了group by严谨模式

2. 关闭这个模式:

在my.cnf 配置文件中的 [mysqld] 下添加一行指令

[mysqld]
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

3. 重启mysql服务
