MySQL Error 1449: How to Fix

MySQL Error 1449: The User Specified as a Definer

The MySQL error 1449, "The user specified as a definer ('web2vi'@'%') does not exist," indicates that the user who created a database object (such as a view, trigger, or procedure) no longer exists in the database. This typically happens when exporting and importing database objects between different databases or servers.

Resolving the Error

There are two possible solutions to this error:

1. Change the DEFINER

  • For views: Create ALTER statements to update the view definitions, removing any DEFINER statements.
  • For stored procedures: Use an UPDATE statement to change the definer for the stored procedure. However, this will affect all databases on the server.

2. Create the Missing User

  • Create the missing user with the same privileges as the original user who created the object.
  • Grant the necessary permissions to the new user.
  • Use the FLUSH PRIVILEGES command to refresh the permissions cache.

Example Using Option 2

If the missing user is "root," use the following commands:

GRANT ALL ON *.* TO 'root'@'%' IDENTIFIED BY 'complex-password';
FLUSH PRIVILEGES;
Copy after login

Alternatively, for MariaDB:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'complex-password';
FLUSH PRIVILEGES;
Copy after login

After creating the missing user, the error should no longer appear when executing the query.
