MySQL Error 1448: Insufficient SUPER Privilege for View Definer
Description
Error 1448 indicates that the MySQL user attempting to create a view does not possess the `SUPER` global privilege, which is required when using a `DEFINER` clause that specifies a user other than the current one, or if the specified definer user does not exist. This error prevents the view creation operation from completing.
Error Message
You need the SUPER privilege for creation view with '%s'@'%s' definer
Known Causes
3 known causesCurrent User Lacks SUPER Privilege
The MySQL user executing the `CREATE VIEW` statement does not possess the necessary `SUPER` global privilege.
Defining View with Different User
The `CREATE VIEW` statement includes a `DEFINER` clause that specifies a user account different from the one currently executing the statement.
Non-Existent Definer User
The user account specified in the `DEFINER` clause of the `CREATE VIEW` statement does not exist on the MySQL server.
Solutions
4 solutions available1. Grant SUPER Privilege Temporarily easy
Grant the SUPER privilege to the user creating the view for the duration of the view creation.
1
Connect to your MySQL server as a user with sufficient privileges (e.g., root).
2
Grant the SUPER privilege to the user who is encountering the error. Replace 'username' and 'hostname' with the actual credentials.
GRANT SUPER ON *.* TO 'username'@'hostname';
FLUSH PRIVILEGES;3
Have the user create the view.
4
Once the view is created, revoke the SUPER privilege from the user.
REVOKE SUPER ON *.* FROM 'username'@'hostname';
FLUSH PRIVILEGES;2. Change View Definer to a User with SUPER Privilege medium
Modify the view's definer to a user account that already possesses the SUPER privilege.
1
Identify a user account on your MySQL server that has the SUPER privilege. This might be the 'root' user or another administrative account.
2
Modify the view's definer using the `ALTER VIEW` statement. Replace 'your_view_name', 'new_definer_username', 'new_definer_hostname', and 'your_database_name' with your specific details.
ALTER VIEW `your_database_name`.`your_view_name` DEFINER = 'new_definer_username'@'new_definer_hostname' SQL SECURITY DEFINER;3
Verify that the view can now be accessed or altered without the SUPER privilege error.
3. Recreate View with a Different Definer medium
Drop the existing view and recreate it, specifying a definer that has the necessary privileges.
1
Connect to your MySQL server as a user with sufficient privileges (e.g., root).
2
Get the `CREATE VIEW` statement for the existing view. You can often find this by running `SHOW CREATE VIEW your_view_name;`.
SHOW CREATE VIEW your_view_name;3
Drop the existing view.
DROP VIEW your_view_name;4
Modify the `CREATE VIEW` statement obtained in step 2 to include a `DEFINER` clause with a user that has SUPER privilege, or omit it if you want the current user to be the definer (assuming they will have SUPER privilege).
CREATE DEFINER='user_with_super'@'hostname' VIEW your_view_name AS ...;5
Execute the modified `CREATE VIEW` statement.
4. Avoid Using DEFINER Clause When Not Necessary easy
When creating views, omit the `DEFINER` clause if the intention is for the current user to be the definer.
1
When creating a view, do not explicitly specify the `DEFINER` clause if the user creating the view is intended to be the definer.
CREATE VIEW my_new_view AS
SELECT column1, column2 FROM my_table;2
Ensure the user creating the view has the necessary privileges to perform the operations within the view's definition. If the view definition itself requires elevated privileges (e.g., accessing system tables), the user might still need them, but the SUPER privilege specifically relates to the definer.
