MySQL 1082: Failed to execute event.

 ?
  1. Check the MySQL error log for detailed error messages. This can be done by locating the error log file (often named `mysqlerror.log` or `mysqld.log`) in the MySQL data directory or as configured in the MySQL configuration file (`my.cnf` or `my.ini`). Use the command `SHOW VARIABLES LIKE 'logerror';` to find the log file location.



  1. Review the event's code by querying the `EVENTS` table in the `information_schema` database to see if there are any apparent issues with the event's syntax or logic. Use the following query to get details about the event:


SELECT * FROM informationschema.EVENTS WHERE EVENTNAME = 'YourEventName';

  1. Verify that the MySQL Event Scheduler is ON. Use the command:


SHOW VARIABLES LIKE 'event_scheduler';
If it's OFF, turn it on with:
SET GLOBAL event_scheduler = ON;

  1. Check if the MySQL user who created the event or the user defined in the DEFINER clause of the event has the necessary privileges to execute the operations defined in the event. Use the following command to check privileges:


SHOW GRANTS FOR 'youruser'@'yourhost';

  1. Ensure that the tables or databases the event is trying to interact with exist and that the user has the correct permissions to perform actions on them.



  1. Examine server resources (CPU, memory usage) and MySQL server status variables related to threads, connections, and errors at the time the event failed. Use commands like `TOP` for system resources and the following MySQL queries for server status:


SHOW STATUS LIKE 'Threads_connected';
SHOW STATUS LIKE 'Threads_running';
SHOW STATUS LIKE '%error%';

Attached error:
