Expression #1 of ORDER BY clause is not in SELECT list, references column 'ekbX1.t0.name' which is not in SELECT list; this is incompatible with DISTINCT
报错信息:
Expression #1 of ORDER BY clause is not in SELECT list, references column 'ekbX1.t0.name' which is not in SELECT list; this is incompatible with DISTINCT
问题原因:
mysql5.7.5及以上版本将sql_mode的ONLY_FULL_GROUP_BY模式默认设置为打开状态,会导致一些错误:
1、我们使用GROUP BY查询时,出现在SELECT字段后面的只能是GROUP BY后面的分组字段,或使用聚合函数包裹着的字段,否则会报错如下信息:
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'database.table.column' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by 2、当使用ORDER BY查询时,不能使用SELECT DISTINCT去重查询。否则会报错如下信息:
Expression #1 of ORDER BY clause is not in SELECT list, references column 'database.table.column' which is not in SELECT list; this is incompatible with DISTINCT
查询验证:
select version(); 查询版本

解决方法:
去除ONLY_FULL_GROUP_BY
1、通过命令关闭: 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';
但该方法在重启Mysql服务后会失效,重启服务后会失效
2、通过修改mysql的配置文件关闭ONLY_FULL_GROUP_BY SQL模式
sudo vim /etc/mysql/conf.d/mysql.cnf
文件底部追加:
[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
保存并重启mysql
sudo service mysql restart
没有所谓的平步青云!
