mysql5.7后用group by 查询时抛出异常

MySQL 5.7.5后实现了对功能依赖的检测。默认启用了only_full_group_by 的SQL模式，会抛出：Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'userinfo.
在session和global 的sql_mode的值都为：
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
执行select @@sql_mode;查询；执行以下两个命令去掉：ONLY_FULL_GROUP_BY就好；
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';
