MySQL 错误 1449:指定为定义者的用户不存在

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

问题描述

当我运行以下查询时，出现错误:

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

错误信息是:

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

为什么我会收到那个错误?我该如何解决?

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

推荐答案

这通常发生在将视图/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，因为创建该对象的用户不再存在.

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:

这在最初导入数据库对象时可能是最简单的，方法是从转储中删除任何 DEFINER 语句.

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

稍后更改定义器有点棘手:

Changing the definer later is a more little tricky:

1. 运行此 SQL 以生成必要的 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';

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

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

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