>I don't change codepage used for my database. But I thought that in case the DBA changes it, I would use UPPER(). How likely/typical is for a DBA to change this?

I would fire a DBA over that.
You can't comfortably change that when a database is in production. It almost certainly would screw up a lot of things (like functions and stored procedures) if you did.
