Is there any way to have a field that will update any time its row is updated?
My situation is that I will have multiple devices writing to a database, and in one case the time that is being kept track of is important. And the devices writing to the database are a bit difficult to keep accurate times on, so instead of writing the time from the devices themselves, I was hoping I could just have a field update itself. I know it can be done on INSERT, but I do not want to do an INSERT every time.
Thanks!
