Re: Uppercase to lowercase trigger?

What if you created separate tables with the fields in uppercase, either
with different names or better yet the same names and a different schema?
It seems you could put triggers on those tables, and have your trigger
translate the field names and make the updates to the real tables instead.

Seems like a lot of work, though, that could be avoided if you could get
your app to drop the quoting of field names, and have it automatically fold
to lower case...
