Thanks Andy.
My understanding, and please correct me if I'm wrong, is that the view
will effectively inherit the table's constraints, because writes to the
view that can't be written to the table will fail on the table. Re:
"will the data be good data," what risks should I be considering?
In terms of rollout, we would 1) create the view, 2) deploy code that
uses the new [view] name, 3) drop the view and rename the table.
Deployments are "rolling" so there would be no downtime. The app and
users shouldn't notice/care if they're hitting the table or the view.
Thank you
I'd assumed new version of app would have new columns in the table.
That's what I meant by good data. New columns would not get populated
by the old app.
But if the table structure isn't changing, then I'd say your plan sounds
like it should work. I've never tried it, personally, but I would if I
were in the same boat.
