Records in that table have a timestamp, so I can tell how long they've been waiting. I want a stored procedure that checks to see if a record has been waiting too long, and if it does, then it will run FlashLightAndSoundHorn.exe. How do I run that program from inside a stored procedure?
A better way to do it is to have an external program that polls the database (or waits to be notified from a database trigger using listen/notify) and have that program do anything that's needed.
