Re: help modeling a schedule system

Well, when I did something similar a very long time ago, I put a "next time to fire" column in the table. Each time an
eventis fired, the application updates that column. 

Was a lot simpler than baroque searches for events that would need firing between the last check and now. Was a lot
cleanerthan creating tons of instances out through the future. 

You could create a stored procedure, if you want, to calculate the next time based on all the possible criteria.

You could, have a "last time fired" column that keeps track of when the event was most recently fired, for
logging/debugging/info.You could have a trigger that updates that "next time to fire" column each time the "last time
fired"column is updated.
