I would think the easiest would be to take a user which is a member of that
group, but I was not able to get that to work. Or more precisely, I was
not able to impersonate as such a user.
You can always look directly into sys.database_permissions, but I don't
really know this information is exposed. In SQL 2005 you can grant a
principal a permission on a schema, which then applies to all objects
in that schema. But I don't think there is a row for every object in
the schema, but I have not investigated this.
