I don't follow. Are you saying something in CDO causes these differences?

I think something in the particular Mysql configurations causes case insensitive identifiers. In that case the case in
the queries wouldn't matter, either.

All these informations should be accessible on the server side through IDBStore, IMappingStrategy, IClassMapping, etc.
If you need them at the client side, it would be possible to implement and contribute a custom IQueryHandler that
returns these mapping informations (or any other server information).
