今天，公司新购买了云服务器，要部署测试环境，测试时发现开发环境没问题，但测试环境却报错了，打开日志分析错误原因，原来时mysql5.7版本的sql_model默认配置了ONLY_FULL_GROUP_BY的原因。

完整错误日志如下：

### Error querying database.  Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'yb_platform_audit.file_illegal_record.doctor_name' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
### The error may exist in com/ks/mapper/FileIllegalRecordMapper.java (best guess)
### The error may involve com.ks.mapper.FileIllegalRecordMapper.rangeOfDoctor-Inline
### The error occurred while setting parameters
### SQL: SELECT doctor_code AS doctorCode, doctor_name AS doctorName, count(doctor_code) AS illegalTimes FROM file_illegal_record WHERE (doctor_code IS NOT NULL AND doctor_code != '' AND outpatient_date BETWEEN ? AND ?) GROUP BY doctor_code ORDER BY illegalTimes desc LIMIT ?, ?

提取错误日志关键字眼：

Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'xxx.xxx' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

大概意思就是说，SQL语句中包含了GROUP BY 聚合操作的情况下，如果在SELECT 中的列没有出现在GROUP BY 中，那么这个SQL 就是不合法的，因为列不在GROUP BY 从句中。

原来是因为mysql中配置的sql_model包含了ONLY_FULL_GROUP_BY，所以对于SQL语句的检查比较严格。

查询sql_model配置：

select @@sql_mode;

在通过分析日志，查看请求中查询数据库的sql语句：

### SQL: SELECT doctor_code AS doctorCode, doctor_name AS doctorName, count(doctor_code) AS illegalTimes FROM file_illegal_record WHERE (doctor_code IS NOT NULL AND doctor_code != '' AND outpatient_date BETWEEN ? AND ?) GROUP BY doctor_code ORDER BY illegalTimes desc LIMIT ?, ?

的确是SELECT 中的列没有出现在GROUP BY 中。

解决方案：

去掉ONLY_FULL_GROUP_BY的默认配置

编辑mysql的配置文件，(Windows系统在mysql安装目录下的my.ini进行编辑，Linux系统在/etc目录下的my.cnf中进行编辑)

在[mysqld]下增加以下内容：

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

就大功告成了~
