Hi

If you want to execute this every hour, this would be better handled in a
scheduled job. Which can be scheduled to run a SQL Statement or stored
procedure every hour.

Although you could schedule the application to run an update query (without
a Trigger or View) every hour, what if the application isn't running all the
time? or if there are muttiple instances of it running?

One point of clarification you cannot execute and Update Query in a View.
