Data Types in AdventureWorks
This topic lists the Microsoft .NET Framework CLR user-defined types, Microsoft SQL Server system data types, and Transact-SQL alias data types that are represented in the AdventureWorks sample database.
CLR User-Defined Types
The following table lists the samples in AdventureWorks that use CLR user-defined types. The samples can be downloaded from the Microsoft SQL Server Samples and Community Projects home page. For more information about CLR user-defined types, see CLR User-Defined Types.
Sample |
Description |
|---|---|
SQL Server Database Engine Samples |
Defines a Currency user-defined data type by using C#. This user-defined data type encapsulates both an amount and a culture that helps determine the correct way to display the amount as a currency value in that culture. The sample also provides a currency conversion function that returns an instance of the Currency user-defined type. |
UDT Utilities |
Includes functions to expose assembly metadata to Transact-SQL: sample streaming table-valued functions to return the types in an assembly as a table, and also functions to return the fields, methods, and properties in a user-defined type. |
User-Defined Data Type (UDT) Sample |
Shows the creation and use of a simple user-defined data type from both Transact-SQL and a client application that uses System.Data.SqlClient. |
UTF8 String User-Defined Data Type (UDT) |
Shows the implementation of a UTF-8 user-defined data type that extends the type system of the database to provide storage for UTF-8 encoded values. This type also implements code to convert Unicode strings to and from UTF-8. |
Calendar-Aware Date/Time UDT |
Defines two user-defined data types, CADatetime and CADate, that provide calendar-aware handling of dates and times. |
Array Parameter Sample |
Passes an array of information from a client to a CLR stored procedure on the server by using a CLR user-defined data type. |
System Data Types
The following table lists the SQL Server system data types and the tables and columns that use them. For more information about system data types, see Data Types (Transact-SQL).
