1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'table1.sale_id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
执行sql语句报错：
SELECT list的表达式#1不在GROUP BY子句中，它包含非聚合列’table1 '。sale_id’在功能上不依赖于GROUP BY子句中的列;这与sql_mode=only_full_group_by不兼容
解决办法：
在mysql中输入
mysql> set sql_mode =‘STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION’;
或
在mysql的安装目录下找到其配置文件my.ini，然后在其最底部添加如下配置：
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
保存文件，重启mysql服务
再次从新查询就OK了！
