Question

There is a way in MySQL to set a value in a specific datetime. For example:

Today in my Table Test there is

Id    Value     Expiration Date
1       0      2012-08-07 18:20
2       0      2012-08-10 15:20

Tomorrow i’d like to have

Id    Value     Expiration Date
1       1      2012-08-07 18:20
2       0      2012-08-10 15:20

The way to do that is just with a job (some timer…)? What is the best practice?

Answer 1

Better way to achive this is by creating EVENT in MySQL as:

DELIMITER $$

CREATE EVENT event1
ON SCHEDULE EVERY 1 DAY
DO
BEGIN
    UPDATE table_name 
    SET Value = 1
    WHERE DATE(Expiration Date) < CURRENT_DATE AND
          Value = 0;
END$$

DELIMITER ;
