MariaDB Error 1454: Missing Trigger DEFINER
Description
This warning indicates that a trigger was created without a `DEFINER` clause, or its `DEFINER` attribute was lost. While the trigger will still execute, it will do so with the privileges of the user who invokes the action that activates it. This can lead to insufficient permissions for the trigger's operations, causing unexpected behavior or failures.
Error Message
No definer attribute for trigger '%s'.'%s'. The trigger will be activated under the authorization of the invoker, which may have insufficient privileges. Please recreate the trigger.
Known Causes
3 known causesMissing DEFINER Clause
The trigger was explicitly created using a `CREATE TRIGGER` statement without including a `DEFINER = 'user'@'host'` clause, causing MariaDB to omit this security attribute.
Database Migration/Import Issues
During database migration or import operations, the `DEFINER` attribute for triggers might be lost or become invalid if the defining user does not exist on the new target system.
Insufficient Creation Privileges
The user attempting to create the trigger lacked the necessary privileges (e.g., `SUPER`) to assign a specific `DEFINER` or create triggers with implicit definers correctly.
