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           |

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

Hi不是获取所有列,而是使用ANY_VALUE(column_name)获取所需的列。它工作得很完美。只是检查。

例如:

SELECT proof_type,any_value("customer_name") as customer_name
FROM `tbl_customer_pod_uploads`
WHERE `load_id` = '78' AND `status` = 'Active' GROUP BY `proof_type`

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。

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!!

在我的例子中,这是我的旧sql_mode

sql_mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"

您可以使用

show variables like "sql_mode";

然后我把它设置成这样

SET sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION';
