本文翻译自:MySQL error 1449: The user specified as a definer does not exist

When I run the following query I get an error: 当我运行以下查询时,我收到一个错误:

SELECT
  `a`.`sl_id`                     AS `sl_id`,
  `a`.`quote_id`                  AS `quote_id`,
  `a`.`sl_date`                   AS `sl_date`,
  `a`.`sl_type`                   AS `sl_type`,
  `a`.`sl_status`                 AS `sl_status`,
  `b`.`client_id`                 AS `client_id`,
  `b`.`business`                  AS `business`,
  `b`.`affaire_type`              AS `affaire_type`,
  `b`.`quotation_date`            AS `quotation_date`,
  `b`.`total_sale_price_with_tax` AS `total_sale_price_with_tax`,
  `b`.`STATUS`                    AS `status`,
  `b`.`customer_name`             AS `customer_name`
FROM `tbl_supplier_list` `a`
  LEFT JOIN `view_quotes` `b`
    ON (`b`.`quote_id` = `a`.`quote_id`)
LIMIT 0, 30

The error message is: 错误消息是:

#1449 - The user specified as a definer ('web2vi'@'%') does not exist

Why am I getting that error? 为什么我会收到这个错误? How do I fix it? 我如何解决它?


#1楼

参考:https://stackoom.com/question/gffc/MySQL错误-指定为定义者的用户不存在


#2楼

The user 'web2vi' does not exist on your mysql server. 您的mysql服务器上不存在用户'web2vi'。

See http://dev.mysql.com/doc/refman/5.1/en/error-messages-server.html#error_er_no_such_user 请参阅http://dev.mysql.com/doc/refman/5.1/en/error-messages-server.html#error_er_no_such_user

If that user does exist, check what servers it can access from, although I would have thought that would be a different error (EG you might have [email protected], but you are accessing the db as [email protected]% (At anything) 如果该用户确实存在,请检查它可以访问哪些服务器,虽然我认为这将是一个不同的错误(EG您可能有web2vi @ localhost,但您正在访问数据库为web2vi @%(在任何地方)

From MySQL reference of CREATE VIEW : MySQL参考 CREATE VIEW

The DEFINER and SQL SECURITY clauses specify the security context to be used when checking access privileges at view invocation time. DEFINER和SQL SECURITY子句​​指定在视图调用时检查访问权限时要使用的安全上下文。

This user must exist and is always better to use 'localhost' as hostname. 此用户必须存在,并且总是更好地使用“localhost”作为主机名。 So I think that if you check that the user exists and change it to 'localhost' on create view you won't have this error. 因此,我认为如果您检查用户是否存在并在创建视图上将其更改为“localhost”,则不会出现此错误。


#4楼

进入编辑例程部分,在底部,将安全类型从Definer更改为Invoker。


#5楼

The user who originally created the SQL view or procedure has been deleted. 最初创建SQL视图或过程的用户已被删除。 If you recreate that user, it should address your error. 如果您重新创建该用户,则应该解决您的错误。

I had your very same problem minutes ago, I ran into this issue after deleting an unused user from mysql.user table, but doing an alter view fixed it, here is a handy command that makes it very simple: 几分钟前我遇到了同样的问题,我在从mysql.user表中删除一个未使用的用户后遇到了这个问题,但是做了一个修改视图修复了它,这里有一个方便的命令,它非常简单:

SELECT CONCAT("ALTER DEFINER=`youruser`@`host` VIEW ",
table_name," AS ", view_definition,";") FROM 
information_schema.views WHERE table_schema='databasename'

Mix this with the mysql command line (assuming *nix, not familiar with windows): 将其与mysql命令行混合使用(假设* nix,不熟悉windows):

> echo above_query | mysql -uuser -p > alterView.sql
> mysql -uuser -ppass databasename < alterView.sql

Note: the command generates and extra SELECT CONCAT on the file, making mysql -uuser -ppass databasename < alterView.sql fail if you don't remove it. 注意:该命令会在文件上生成额外的SELECT CONCAT,如果不删除它,则会使mysql -uuser -ppass databasename < alterView.sql失败。
