一、異常信息

org.springframework.jdbc.BadSqlGrammarException: 
### 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 'daotable.he_store_file.file_url' 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/zbq/springbootbase/mysql/HeStoreFileDAO.java (best guess)
### The error may involve com.zbq.springbootbase.mysql.HeStoreFileDAO.findFileInfoByFileTypeAndStoreIdList-Inline
### The error occurred while setting parameters
### SQL: SELECT store_id, file_url FROM he_store_file WHERE (1=1)  AND (store_id in (8310596))  AND (file_type = ? ) GROUP BY store_id

二、分析原因

　　ONLY_FULL_GROUP_BY的意思是：對於GROUP BY聚合操作，如果在SELECT中的列，沒有在GROUP BY中出現，那么這個SQL是不合法的，因為列不在GROUP BY從句中，也就是說查出來的列必須在group by后面出現否則就會報錯，或者這個字段出現在聚合函數里面。

命令行執行：

SELECT @@SESSION.sql_mode;

發現：

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

第一項默認開啟ONLY_FULL_GROUP_BY。

 

三、解決方案
1.臨時解決方案

關掉ONLY_FULL_GROUP_BY！

set @@GLOBAL.sql_mode='';
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';

 

2.永久解決方案

修改my.ini 配置（如果你們mysql 沒有這個文件，就把my-default.ini 改成my.ini）

在 [mysqld]和[mysql]下添加
 sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
