MySQL 1083: Invalid event time interval.
MySQL 1083: Invalid event time interval.
When encountering the error "1083: Invalid event time interval" in MySQL, the user should immediately:
- Identify the Event and Query Causing the Error:
- Run `SHOW EVENTS;` to list all events in the current database.
- Identify the event related to the error (based on recent changes or the error context).
- Check the Event Definition:
- For the identified event, run `SHOW CREATE EVENT eventname;` replacing `eventname` with the name of the suspect event. This will display the event's definition, including the schedule.
- Validate the Event Schedule Syntax:
- In the event definition, specifically look at the `SCHEDULE` clause. The interval must be correct according to MySQL syntax, e.g., `EVERY 1 DAY` or `EVERY 1 HOUR`. Common issues include incorrect interval values or units.
- Correct the Interval if Necessary:
- If the interval is found to be incorrect, modify the event with the correct interval syntax. Use:ALTER EVENT event_name
ON SCHEDULE EVERY correct_interval
STARTS start_time
ENDS end_time;
- Replace `eventname`, `correctinterval`, `starttime`, and `endtime` with the respective values.
- Verify the Change:
- Run `SHOW CREATE EVENT event_name;` again to ensure the changes have been applied correctly.
- Monitor the Event Execution:
- Check the MySQL error log for any subsequent instances of the same error.
- Optionally, you can use `SELECT * FROM informationschema.EVENTS WHERE EVENTNAME = 'event_name';` to monitor the event's status and last execution time.
This approach directly addresses the specific error by validating and correcting the event schedule, the most common cause of this error.
