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

当MySQL中的一个存储过程或函数被定义时，可能会指定一个definer，即定义者。当该存储过程或函数被执行时，MySQL会检查definer是否存在。如果definer不存在，则会出现“1449-The user specified as a definer does not exist”错误。

解决此问题的方法是创建一个与definer相同的用户。例如，如果错误信息中指定的definer是'development'@'%'，则可以使用以下命令创建该用户：

CREATE USER 'development'@'%' IDENTIFIED BY 'password';

然后，将该用户授予执行存储过程或函数的权限：

GRANT EXECUTE ON PROCEDURE database.procedure_name TO 'development'@'%';

其中，'database'是存储过程或函数所在的数据库名称，'procedure_name'是存储过程或函数的名称。

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

The error message "The user specified as a definer ('yhz'@'%') does not exist" indicates that there is an issue with the user specified in a SQL statement. It seems that the user 'yhz' does not exist in the database or has been removed.

To resolve this issue, you can try the following steps:

1. Check the spelling and capitalization of the user name. Make sure it is correct.
2. Verify if the user 'yhz' exists in the database. You can use the following SQL command to check:

   SELECT user, host FROM mysql.user WHERE user = 'yhz';

If the user does not exist, you will need to create it using the appropriate SQL command.
3. If the user exists, but you are still getting the error, it is possible that the user's privileges have been revoked or modified. In this case, you may need to grant necessary privileges to the user using the GRANT statement.

For example, if you want to grant all privileges to the user 'yhz', you can use the following SQL command:

   GRANT ALL PRIVILEGES ON *.* TO 'yhz'@'%';   ```

   Make sure to replace '*' with the appropriate database and table names if you want to limit the privileges to specific databases or tables.

By following these steps, you should be able to resolve the "user specified as a definer does not exist" error.

The user specified as a definer ('admin'@'%') does not exist报错

报错信息 "The user specified as a definer ('admin'@'%') does not exist" 表示指定的用户 'admin'@'%' 不存在。

这个错误通常发生在以下情况下：
1. 您尝试将权限授予一个不存在的用户。
2. 您可能没有使用正确的用户名或主机名。

请确保在授权语句中使用正确的用户名和主机名，并确保该用户存在于数据库中。您可以执行以下步骤来解决这个问题：
1. 确认是否正确拼写了用户名 'admin'。
2. 确认是否正确指定了主机名。如果要将权限授予在任何主机上访问，请使用 '%' 作为主机名，而不是 'localhost'。
3. 确认该用户 ('admin') 在数据库中存在，可以使用 `SHOW GRANTS FOR 'admin'@'%';` 查询语句来验证用户是否存在。

如果问题仍然存在，请检查您的数据库配置和权限设置，确保用户被正确创建和授权。如果需要进一步的帮助，请联系您的数据库管理员。
