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).

Hey all, I am currently researching ways to compare databases via an XSD schema. I wrote a small app that creates a dataset from a database and exports that dataset to XSD. This gives me an XSD file with tables and relationships representing the entire database. At this point, I am trying to find ways to compare these schemas. Does anybody know of a way to do this easily and to record differences if there are any?

Most of the programs jus do tables, that is the easy part. Also I was wondering how you would compate text fiels progammatically and kick back a report using...

I am trying to compare the tables in two similar databases using the SQLDMO object. I am able to use this object to access different SQL servers and choose two different databases.

In the followng stored procedure, 2 NULL columns (COMM) are selected into 2 different SP variables and compared for equal. They are both NULL, but do not compare as equal. When the Not NULL columns (SALARY) are compared, they do compare as equal.
