When you need to compare two tables to see what the differences are, are there any tools or shortcuts you use, or do you handcode the SQL to compare the two tables?

Background: In my SQL Server environment, I created a stored procedure which inspects the metadata of the two tables/views, creates a query (as dynamic sql) which joins the two tables on the specified key columns, and compares data in the compare columns, reporting key differences and data differences. The query can either be printed and modified/copied or just excecuted as is. We are not allowed to create stored procedures in our Teradata environment, unfortunately.
