Have you ever wanted to test a table in the database for the correct structure? Ever had someone make a column nullable that shouldn't have been? ever have someone make a column VARCHAR instead of NVARCHAR? INT instead of BIGINT? SMALLDATETIME instead of DATETIME? This is an easy way for bugs to creep in - when the code is written for one version of the database and then someone makes a change... So if you haven't been testing your tables (SQL should be TDD'd too), perhaps you should... Here is a handy stored procedure you could use that describes a table in an easy-to-test way.
