SQLSTATE[42000]: this is incompatible with sql_mode=only_full_group_by in

执行

SELECT *FROM test WHERE id>1 GROUP BY name having AVG(age)>10 ORDER BY id desc limit 1

提示错误

Fatal error: Uncaught PDOException: SQLSTATE[42000]: Syntax error or access violation: 1055 Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'aaa.test.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by in

这个错误是由于 MySQL 的新版本中默认开启了ONLY_FULL_GROUP_BY模式，即在 GROUP BY 语句中的 SELECT 列表中，只能包含分组或​聚合函数​，不能包含其他列

临时解决方案:

执行
set sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

仅对下次连接生效，不影响当前会话，且MySQL重启后失效，因为MySQL重启时会重新读取配置文件里对应值，如果需永久生效需要修改配置文件里的值。

永久解决方案 

修改/etc/my.cnf，将sql_mode=中的only_full_group_by给删掉

保存退出，重启服务器，即可永久生效
