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 |
+----+---------+---------+---------+----------+-----------+------------+---------------+--------------+------------+--------+---------------------+---------------------+
| 1 | 1 | 78 | 1 | 21.1212 | 21.5454 | 1 | 1 | id_Card.docx | 0 | Active | 2017-01-27 11:30:11 | 2017-01-27 11:30:14 |
+----+---------+---------+---------+----------+-----------+------------+---------------+--------------+------------+--------+---------------------+---------------------+
你可以禁用
sql_mode = only_full_group_by
通过一些命令，你可以尝试通过终端或MySql IDE
mysql> 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';
mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
This
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
将通过这个命令改变MySQL中的sql模式来简单地解决，
SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));
这也适用于我。
我使用这个，因为在我的项目中有很多这样的查询，所以我只是将这个sql模式更改为only_full_group_by
或者简单地包括SELECT语句指定的GROUP BY子句中的所有列。sql_mode可以保持启用状态。
谢谢你！: -)
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!!
