mysql group_by 的问题

ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'DBname.table.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

平台： Mac OS X
报错： incompatible with sql_mode=only_full_group_by
版本： mysql  Ver 14.14 Distrib 5.7.16, for osx10.11 (x86_64) using  EditLine wrapper
参考： https://stackoverflow.com/questions/23921117/disable-only-full-group-by 
搜索： "version 5.7.11 running on Mac OS X"

解决办法：
1）命令行登录mysql
2）执行语句：

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";

设置好之后没有重启就可以；重启可能导致配置消失；

3）搞定

==================== 成功案例 ======================
mysql> select t.id from transactions t,transaction_info i where t.id=i.t_id   group by i.email order by i.email ASC;
