Error Message
Failed to drop %s
Known Causes
3 known causesInsufficient User Privileges
The database user attempting to drop the event lacks the necessary `EVENT` or `SUPER` privileges.
Event Not Found
The event specified in the `DROP EVENT` statement does not exist in the current database or schema.
Incorrect Database Context
The `DROP EVENT` statement was executed while not connected to or explicitly specifying the database where the event is defined.
Solutions
3 solutions available1. Verify Event Name and Existence easy
Ensure the event name is spelled correctly and the event actually exists in the database.
1
Connect to your MariaDB server using a client like `mysql` or `mariadb`.
mariadb -u your_user -p2
Select the database where the event is expected to be.
USE your_database_name;3
List all events in the current database to confirm the exact name.
SHOW EVENTS;4
Attempt to drop the event using the confirmed name.
DROP EVENT IF EXISTS your_event_name;2. Check User Privileges for Event Management medium
Confirm that the user attempting to drop the event has the necessary `DROP` privilege on events.
1
Connect to your MariaDB server with a user that has administrative privileges (e.g., `root`).
mariadb -u root -p2
View the privileges granted to the user who is encountering the error.
SHOW GRANTS FOR 'user_who_has_error'@'localhost';3
If the user lacks `DROP` privilege on events, grant it. Replace `user_who_has_error` and `localhost` with the actual user and host.
GRANT DROP ON your_database_name.* TO 'user_who_has_error'@'localhost';
FLUSH PRIVILEGES;4
Have the user who encountered the error try to drop the event again.
DROP EVENT your_event_name;3. Investigate Event Dependencies or Locks advanced
Rule out any potential blocking issues, such as the event being actively executed or having complex dependencies.
1
Connect to your MariaDB server.
mariadb -u your_user -p2
Check for any currently running events or processes that might be interfering.
SHOW PROCESSLIST;3
If the event is currently executing, wait for it to finish or, as a last resort, kill the process. Use caution when killing processes.
KILL process_id;4
Examine the event's definition for any complex logic or dependencies that might be preventing its termination. You can retrieve the event definition using:
SHOW CREATE EVENT your_event_name;5
After ensuring the event is not actively running and there are no apparent blocking dependencies, try dropping it again.
DROP EVENT your_event_name;
