SQL Server 2005 allows you to create .NET CLR objects that can be used
inside SQL Server.

using.

For reasons of performance, security and maintainability, it is best to
avoid the use of external library function calls unless there is a very
special need. As an example, if you are basically wanting access to
functions for string parsing or financial calculations, then this could be
implemented using advanced SQL techniques or perhaps implemented at the
application level.
