How to Set a Timer in MySQL
November 22, 2023
This guide covers how to automate SQL commands in MySQL. You’ll usually want to do this to schedule routine tasks like data backups, cleanup and reporting during off-peak hours.
What are MySQL Events?
MySQL's event scheduler is a built-in feature for executing tasks at scheduled times. It's similar to cron jobs in Unix/Linux systems.
Enabling the Event Scheduler
Before creating events, ensure the event scheduler is enabled:
SET GLOBAL event_scheduler = ON;
Alternatively, check its status:
SHOW VARIABLES LIKE 'event_scheduler';
How to Create a Basic Event in MySQL
You can create an event with the following syntax:
CREATE EVENT my_event ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 HOUR DO UPDATE my_table SET my_column = my_value;
This event updates my_table
one hour from the current time.
Advanced Scheduling
For more complex scheduling, you can use a couple clauses in the ON SCHEDULE
section.
Repeating Events
To repeat an event, use the EVERY
clause:
CREATE EVENT my_repeating_event ON SCHEDULE EVERY 1 DAY STARTS CURRENT_TIMESTAMP DO INSERT INTO my_table (my_column) VALUES (my_value);
This will insert a new record into my_table
every day.
Specifying Start and End Times
Control when an event starts and optionally when it ends:
CREATE EVENT my_timed_event ON SCHEDULE EVERY 1 WEEK STARTS '2023-01-01 00:00:00' ENDS '2023-12-31 23:59:59' DO CALL my_procedure();
This calls my_procedure
weekly throughout 2023.
You could ship faster.
Imagine the time you'd save if you never had to build another internal tool, write a SQL report, or manage another admin panel again. Basedash is built by internal tool builders, for internal tool builders. Our mission is to change the way developers work, so you can focus on building your product.
Managing Events
Viewing Existing Events
List all events:
SHOW EVENTS;
Altering Events
Modify an event's definition:
ALTER EVENT my_event ON SCHEDULE EVERY 2 DAYS;
Deleting Events
Remove an event when it's no longer needed:
DROP EVENT IF EXISTS my_event;
Integrating with Basedash
Basedash is a solid way to streamline your MySQL workflows. Basedash gives you a fully-functional admin interface for your MySQL database in just a couple clicks. You can edit data, share SQL queries with your team and build collaborative dashboards.
