I'm literally thinking as I'm typing (dangerous combination).

If you queried sys.columns....

select * from sys.columns where max_length = 36 and system_type_id = 175

I "think" that would give you the columns. Now, you'd have to take the object_ids and join to sys.tables to get the table names.

It would seem to me that any loop to construct a full script would use that at the beginning.

Again, just a partial idea, but maybe that can help...(I'd be tempted to write a short .NET program to iterate through the rows and generate a t-sql script)
