Please see my past answer to a related question:
Polling Database with Timer[^].

If you''re having trouble figuring out how to connect to the database and run your SQL command, you might want to start with a tutorial. You can find some on google[^].

As stated in the comments, you probably will want to use a timer control in order to run your SQL every hour. For that you should research the timer class on MSDN.[^]
