MySQL错误1449:指定为定义者的用户不存在 [英] MySQL error 1449: The user specified as a definer does not exist

问题描述

当我运行以下查询时，我得到一个错误:

When I run the following query I get an error:

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

错误消息是:

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

为什么会出现该错误?我该如何解决?

Why am I getting that error? How do I fix it?

推荐答案

当创建一个对象的用户不再存在时，将视图/触发器/过程从一个数据库或服务器导出到另一个数据库或服务器时，通常会发生这种情况.

This commonly occurs when exporting views/triggers/procedures from one database or server to another as the user that created that object no longer exists.

您有两个选择:

在最初导入数据库对象时，通过从转储中删除任何DEFINER语句，这可能最容易做到.

This is possibly easiest to do when initially importing your database objects, by removing any DEFINER statements from the dump.

稍后更改定义器比较棘手:

Changing the definer later is a more little tricky:

1. 运行此SQL生成必要的ALTER语句

1. Run this SQL to generate the necessary ALTER statements

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

复制并运行ALTER语句

Copy and run the ALTER statements

如何更改存储过程的定义器

示例:

How to change the definer for stored procedures

Example:

UPDATE `mysql`.`proc` p SET definer = 'user@%' WHERE definer='root@%'

请小心，因为这将更改所有数据库的所有定义器.

Be careful, because this will change all the definers for all databases.

如果在使用MySQL数据库时发现以下错误:

If you've found following error while using MySQL database:

The user specified as a definer ('someuser'@'%') does not exist`

然后您可以解决 通过使用以下命令:

Then you can solve it by using following :

GRANT ALL ON *.* TO 'someuser'@'%' IDENTIFIED BY 'complex-password';
FLUSH PRIVILEGES;

这就像一种魅力-您只需将someuser更改为丢失用户的名称.在本地开发服务器上，您通常可能只使用root.

This worked like a charm - you only have to change someuser to the name of the missing user. On a local dev server, you might typically just use root.

还要考虑您是否实际上需要授予用户ALL权限，或者他们是否可以做得更少.

Also consider whether you actually need to grant the user ALL permissions or whether they could do with less.
