mysql报1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column

我的MySQL版本为：MySQL-8.0.12

解决方案：
先执行

select @@global.sql_mode;

结果为：

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;

再执行下面语句

set @@global.sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';

然后重启数据库，才会生效。
