Question

I have a problem:

How I can insert a row and delete it X time?

I think something like INSERT the value whit a time stamp and add a task to delete it.

But I don’t have idea how to add MySQL task and if here is a better method.

Answer 1

you need to use event scheduler from MySQL:

the basic about MySQL scheduler is:

CREATE EVENT myevent
    ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 HOUR
    DO
      UPDATE myschema.mytable SET mycol = mycol + 1;
