MySQL报错org.springframework.jdbc.BadSqlGrammarException: ### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression

org.springframework.jdbc.BadSqlGrammarException:
### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Expression #3 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘card.mall_refund_order.status‘ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

 

 

问题出现的原因: 
MySQL 5.7.5及以上功能依赖检测功能。如果启用了ONLY_FULL_GROUP_BY SQL模式(默认情况下),MySQL将拒绝选择列表,HAVING条件或ORDER BY列表的查询引用在GROUP BY子句中既未命名的非集合列,也不在功能上依赖于它们。(5.7.5之前,MySQL没有检测到功能依赖关系,默认情况下不启用ONLY_FULL_GROUP_BY。有关5.7.5之前的行为的说明,请参见“MySQL 5.6参考手册”。)

解决方法一:

打开navcat,

用sql查询:

select @@global.sql_mode

查询出来的值为:

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

去掉ONLY_FULL_GROUP_BY,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’;

 

解决方法二:

成功的步骤:

iterm打开

sudo vim /etc/mysql/conf.d/mysql.cnf

滚动到文件底部复制并粘贴

[mysqld] 
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

到文件的底部

保存并退出输入模式

sudo service mysql restart

重启MySQL。
