我用WAMP服务器在我的windows PC上使用MySQL 5.7.13

我的问题是在执行这个查询时

SELECT *
FROM `tbl_customer_pod_uploads`
WHERE `load_id` = '78' AND
      `status` = 'Active'
GROUP BY `proof_type`

我总是得到这样的错误

SELECT列表中的表达式#1不在GROUP BY子句中,包含未聚合的列returntr_prod.tbl_customer_pod_uploads。id',它不依赖于GROUP BY子句中的列;这与sql_mode=only_full_group_by不兼容

你能告诉我最好的解决办法吗?

我需要这样的结果

+----+---------+---------+---------+----------+-----------+------------+---------------+--------------+------------+--------+---------------------+---------------------+
| id | user_id | load_id | bill_id | latitude | langitude | proof_type | document_type | file_name    | is_private | status | createdon           | updatedon           |

下面的方法解决了我的问题:

在ubuntu中

类型:sudo vi /etc/mysql/my.cnf

输入A进入插入模式

在最后一行粘贴下面两行代码:

[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

按esc退出输入模式

Type :wq to save and close vim.

输入sudo service mysql restart重启mysql。

For the query to be legal in SQL92, the name column must be omitted from the select list or named in the GROUP BY clause. SQL99 and later permits such nonaggregates per optional feature T301 if they are functionally dependent on GROUP BY columns: If such a relationship exists between name and custid, the query is legal. This would be the case, for example, were custid a primary key of customers. MySQL 5.7.5 and up implements detection of functional dependence. If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list, HAVING condition, or ORDER BY list refer to nonaggregated columns that are neither named in the GROUP BY clause nor are functionally dependent on them. via MySQL :: MySQL 5.7 Reference Manual :: 12.19.3 MySQL Handling of GROUP BY

你可以用下面的命令改变sql模式来解决这个问题:

SET GLOBAL sql_mode=(SELECT (@@sql_mode,'ONLY_FULL_GROUP_BY', "));

和…记得重新连接数据库!!

转到phpmyadmin并打开控制台并执行此请求

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

在my.ini中,这样写:

[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"

取决于你的版本。或者:

[mysqld]
sql_mode = ""

或者简单地删除这个:ONLY_FULL_GROUP_BY

从它的外观来看,我认为分组多列/字段不会损害你的结果。你为什么不试试这样加入这个群呢:

GROUP BY `proof_type`, `id`

这将首先按proof_type进行分组,然后再按id进行分组。我希望这不会改变结果。在某些/大多数情况下,按多列分组会给出错误的结果。

MySQL 8.0升级

你的sql-mode不会有NO_AUTO_CREATE_USER,因为它已经被删除了,正如这里提到的-如何设置sql-mode-in-my-cnf-in-mysql-8

[mysqld]
sql-mode = "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"

此外,如果有人没有my.cnf文件,那么他们可以在/etc/mysql/my.cnf中创建一个新的文件,然后添加上面的行。
