Working with User-Defined Types in SQL Server
User-defined type (UDT) functionality can be accessed in SQL Server from the Transact-SQL language by using regular query syntax. UDTs can be used in the definition of database objects, as variables in Transact-SQL batches, in functions and stored procedures, and as arguments in functions and stored procedures.
