错误提示：
.... which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
查看sql_mode:
select @@global.sql_mode
--->
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
重新设置值
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'; -- 此处去掉了 ONLY_FULL_GROUP_BY
