My first thought is that, since you are searching on field name, you need the *metadata* in the database to be case (in)sensitive. This is achieved by going to the virtual database via Database Management in denodo, and setting the Identifiers charset setting to Unicode for case sensitive, or restricted which is the default, for case insensitive. Make this change, and it should allow the catalog to make case sensitive queries to the database’s metadata, eg field name. But, this doesn’t handle the literal string comparisons, that is handled by the property you mentioned, and determines whether “ABC” = “abc” -> true. Again, not the metadata like fieldname.
Hope this helps!
