Hi Kaniz, thank you for your feedback.
Databases that I have to link cannot be changed, other teams and products rely on those databases as well, this change would be disruptive.

I think this is a limitation in the unity catalog behaviour, as it should take in account that external databases could have a case sensitive collation, either:

- keeping the name of the tables as they are, leaving up to the user to deal with case issues for external tables.
- remapping that internally and hide it to the user
- providing some API where to hook on in the database registration, or perform it programmatically.

So I'll open up a ticket support for it.

Thank you
