Readme_UDT Sample

This sample works only with SQL Server 2005 and SQL Server 2008. It will not work with any version of SQL Server earlier than SQL Server 2005.

The UserDefinedDataType sample shows the creation and use of a simple user-defined data type from both Transact-SQL and a client application using System.Data.SqlClient.

When you compile common language runtime integration samples, the path of the version of the Microsoft .NET Framework compiler that was distributed with SQL Server must be the first Framework directory in the PATH environment variable. The location of the compiler that is included with SQL Server is either drive:\WINNT\Microsoft.NET\Framework\v2.0.xxxxx or drive:\Windows\Microsoft.NET\Framework\v2.0.xxxxx, where drive is the installation drive and xxxxx is the version of the .NET Framework that is included with SQL Server.

The default installation directory is C:\Program Files\Microsoft SQL Server\100\Samples\Engine\Programmability\CLR\UserDefinedDataType.

SQL Server samples and sample databases must be downloaded and installed before you can view or work with them. For more information, see Considerations for Installing SQL Server Samples and Sample Databases.

A developer wants to represent, persist, and manipulate complex numbers.

Transact-SQL, Visual C# and Visual Basic.

The UserDefinedDataType sample uses the following SQL Server features:

Before running this sample, make sure the following software is installed:

  • Microsoft SQL Server or Microsoft SQL Server Express. You can obtain SQL Server Express free of charge from the SQL Server Express Documentation and Samples Web site.
  • The AdventureWorks database that is available at the SQL Server Developer Web site.
  • The SQL Server Database Engine samples that are available at the SQL Server Developer Web site.
  • .NET Framework SDK 2.0 or Microsoft Visual Studio 2005. You can obtain .NET Framework SDK free of charge. See Installing the .NET Framework Documentation.

If you have not already created a strong name key file, generate the key file using the following instructions.

  1. Open a Microsoft Visual Studio 2005 command prompt. Click Start, point to All Programs, point to Microsoft .NET Framework SDK 2.0, and then click SDK Command Prompt.

    -- or --

    Open a Microsoft .NET Framework command prompt. Click Start, point to All Programs, point to Microsoft .NET Framework SDK 2.0, and then click SDK Command Prompt.

  2. Use the change directory command (CD) to change the current directory of the command prompt window to the folder where the samples are installed.

    To determine the folder where samples are located, click the Start button, point to All Programs, point to Microsoft SQL Server, point to Documentation and Tutorials, and then click Samples Directory. If the default installation location was used, the samples are located in <system_drive>:\Program Files\Microsoft SQL Server\100\Samples.
  3. At the command prompt, run the following command to generate the key file:

    sn -k SampleKey.snk

    For more information about the strong-name key pair, see "Security Briefs: Strong Names and Security in the .NET Framework" in the .NET Development Center on MSDN.

To build the sample, do the following:

  1. Compile the sample by using Visual Studio 2005 and the provided Visual Studio solution, or by using Microsoft MSBuild, which is included in the .NET Framework SDK 2.0. Run a command similar to the following at the command prompt:

    msbuild /nologo /verbosity:quiet /property:Configuration=Debug CS\ComplexNumber.sln

  2. Ensure that the AdventureWorks database is installed, or, if necessary, create the database in which you want to install the samples.

  3. Open the scripts\installCS.sql or scripts\installVB.sql file, depending on whether you compiled the Visual C# project or the Visual Basic project, in SQL Server Management Studio. Run the script that is contained in the file, or run a command similar to the following at the command prompt:

    sqlcmd -E -I -i Scripts\InstallCS.sql

    This file contains the script to install and register the CLR Integration UDT sample in SQL Server.

To run the sample, do the following:

  1. Open the scripts\test.sql file in SQL Server Management Studio and run the script that is contained in the file. Or, run the following command at the command prompt:

    sqlcmd -E -I -i Scripts\test.sql

    This script invokes the sample CLR Integration UDT objects from Transact-SQL.

  2. Execute clientsample.exe, specifying the name of the database into which the sample user-defined data type has been installed on the command line. This simple console application invokes the sample user-defined data type by using System.Data.SqlClient.

To remove the sample, do the following:

  1. Open the scripts\cleanup.sql file in SQL Server Management Studio and run the script that is contained in the file. Or, run the following command at the command prompt:

    sqlcmd -E -I -i Scripts\cleanup.sql

    This script removes the UDT sample.

The CLR for SQL Server or SQL Server Express must be enabled for this sample to work correctly.
