ERROR 1055 (42000): Expression #1 of ORDER BY clause is not in GROUP BY..sql_mode=only_full_group_by

MySQL错误：Expression #1 of ORDER BY clause is not in GROUP BY clause and contains nonaggregated column 'DB.table.column' which is not functionally dependent on columns in GROUP BY clause; this is incompatible
with sql_mode=only_full_group_by

解决办法1:

（临时）在命令行中登陆Mysql，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';

解决办法2:

（永久）在Mysql的配置文件my.cnf修改sql_mode值（去掉里面的ONLY_FULL_GROUP_BY），重启MySQL即可。

----- 配置文件my.conf在哪 -----

（0）Linux下，参考：Linux下MySQL配置文件my.ini位置，http://www.linuxidc.com/Linux/2013-01/77389.htm

（1）OSX下，需要自己复制出来， sudo cp /usr/local/mysql/support-files/my-medim.cnf /etc/my.cnf，重启mysql即可

（2）windows下，参考Windows下MySQL5.6查找my.ini配置文件，http://blog.csdn.net/mayor125/article/details/54140454
