how can i create a mysql event that repeats every day, but also repeats every four minutes betweent eh hours of midnight and 9am

To create a MySQL event that repeats every day but also repeats every four minutes between the hours of midnight and 9 AM, you can define two separate schedules for the event. You'll need to create a stored procedure that encapsulates the logic you want to execute at each interval. Here's how you can do it:

1. Create a stored procedure that contains the logic you want to execute.
2. Create an event with two schedules: one for daily execution and one for execution every four minutes between midnight and 9 AM.

Here's an example of how you can achieve this:

```sql
-- Step 1: Create a stored procedure
DELIMITER $$
CREATE PROCEDURE DailyEventProcedure()
BEGIN
    -- Your logic goes here
    -- This is just an example, replace it with your actual logic
    INSERT INTO your_table (column1, column2) VALUES (value1, value2);
END$$
DELIMITER ;

-- Step 2: Create an event with two schedules
CREATE EVENT DailyEvent
ON SCHEDULE
    -- Schedule 1: Daily execution at 9 AM
    EVERY 1 DAY
    AT '9:00:00'
DO
    CALL DailyEventProcedure();

-- Schedule 2: Every 4 minutes between midnight and 9 AM
CREATE EVENT FourMinuteEvent
ON SCHEDULE
    EVERY 4 MINUTE
    STARTS '00:00:00'
    ENDS '09:00:00'
DO
    CALL DailyEventProcedure();
```

Replace `your_table`, `column1`, `column2`, `value1`, and `value2` with your actual table name, column names, and values you want to insert.

This setup will execute the `DailyEventProcedure` stored procedure daily at 9 AM and every four minutes between midnight and 9 AM. Adjust the schedules and procedure as per your specific requirements.
