We are like a living room as seen in a TV series... everyone can watch for
free, at any time the show is running.

Views are VERY BUGGY. No joke. And we inherited those bugs from the unnamed
company. Just search our bug tracker and you will find at least 10 serious
issues. As it's not enough, Dmitry Kuzmenko logged two more today. The only
serious one I remember I fixed (shown among closed bugs) is that one that
came "only" from IB4: joins of views using indices in the underlying tables
kill the engine at prepare time, no need to run the query. Several of those
bugs come from 1994 and never were fixed.

I use views in my applications. If I happen to run in one of the bugs, I
will find a way to restructure my SQL view so it doesn't fail. It's like
running near the nest of very aggressive bees.

It was fixed according to Ann suggestions. If someone's still not happy with
the new "virtual behavior" for views, please take the sources and branch a
new fork of the original product. Questions about the philosophical
foundation for the new behavior can be sent to Jason Wharton. <g> I think he
will copy/paste one of his letters to explain you. You get the activity on
the view, not on the underlying tables.

The bottom line is that the behavior is different than IB6.
