Instead of using CHECKSUM, timestamp, or other methods, hashing data may be a good alternative.

A common scenario in data warehousing applications is knowing what source system records to update, what data needs to be loaded and which data rows can be skipped as nothing has changed since they were last loaded. Another possible scenario is the need to facilitate searching data that is encrypted using cell level encryption or storing application passwords inside the database.

Data Hashing can be used to solve this problem in SQL Server.
