mysql问题解决SELECT list is not in GROUP BY clause and contains nonaggregated column
今天在Ubuntu下的部署项目,发现一些好好的列表页面发生
1055:Expression #11 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'ppm_c.ppm_flow_starting_dealing.status' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
查了下问题出现的原因:
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:
1.临时修改
查询
select @@global.sql_mode

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';
这种方式mysql服务重启后就失效了
2.永久解决
修改配置文件
我的配置文件是/etc/mysql/mysql.conf.d/mysqld.cnf
在[mysqld]下面添加
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
重启mysql
问题解决
