SELECT list is not in GROUP BY clause and contains

select @@global.sql_mode;

可以看到模式中包含了ONLY_FULL_GROUP_BY，只要没有这个配置即可。
我的Mysql版本是5.7.21，默认是带了ONLY_FULL_GROUP_BY模式。

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,
ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

2.重设模式值

set @@global.sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE, <br/>ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION;
