How to compare two databases using their DDLs?

Hello all!

My question is: how to compare two database structures if I only have
their DDL files? As the result I would expect an sql-script upgrating
one database structure to another.

The most 3rd-party tools I tested require connection to both databases.

Personally, I would use the DDL to create two databases, then compare them
with a tool. If you want to be able to compare two databases without having
MSSQL available, then you would have to look for a tool which supports that.
I believe ERwin does, although I'm not sure (and it's rather expensive).
