CLR User-Defined Functions
User-defined functions are routines that can take parameters, perform calculations or other actions, and return a result. In Microsoft SQL Server 2005, you can write user-defined functions in any Microsoft .NET Framework programming language, such as Microsoft Visual Basic .NET or Microsoft Visual C#.
There are two types of functions: scalar, which returns a single value, and table-valued, which returns a set of rows.
The following table lists the topics in this section.
