Hello World Sample
Updated: 5 December 2005
The Hello World sample demonstrates the basic operations that are involved in creating, deploying, and testing a simple common language runtime (CLR) integration-based stored procedure. This sample also demonstrates how to return data through an output parameter
and through a record, which are dynamically constructed by the stored procedure and returned to the client.

Jane is a developer for Adventure Works Cycles. She has to understand the basics in using CLR integration stored procedures.
Transact-SQL, Visual C# and Visual Basic.
The Hello World sample uses the following features of SQL Server.
Before running this sample, make sure the following software is installed:
- Microsoft SQL Server 2005 or Microsoft SQL Server 2005 Express Edition (SQL Server Express). You can obtain SQL Server Express free of charge from the SQL Server 2005 Express Edition Documentation and Samples
- The AdventureWorks database which is included with SQL Server 2005, and is also available at the SQL Server Developer
- The SQL Server 2005 Database Engine samples. These samples are included with SQL Server 2005. You can download the latest version of the samples at the SQL Server Developer
- .NET Framework SDK 2.0 or Microsoft Visual Studio 2005. You can obtain .NET Framework SDK free of charge. See
Installing the .NET Framework SDK.
Building the Sample
If you have not already created a strong name key file, generate the key file using the following instructions.
To generate a strong name key file
- 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.
- Use the change directory command (CD) to change the current directory of the command prompt window to the folder where the samples are installed.
Note: To determine the folder where samples are located, click the Start* button, point to
All Programs, point to Microsoft SQL Server 2005, 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\90\Samples.*
- At the command prompt, run the following command to generate the key file:
sn -k SampleKey.snk Important: 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 Hello World sample
- 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 a command prompt:
msbuild /nologo /verbosity:quiet /property:Configuration=Debug CS\HelloWorld.sln
- Make sure that the AdventureWorks database is installed.
- If you did not install the SQL Server engine samples in the default location, modify the path in the CREATE ASSEMBLY portion of the script in Scripts\InstallCS.sql and Scripts\InstallVB.sql to refer to the location where the samples were installed.
- If you are not an administrator for the SQL Server instance you are using, you must have an administrator grant you
CreateAssembly permission to complete the installation.
- 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 Microsoft . Run the script that is contained in the file, or run a command similar to the following in
a command prompt window: sqlcmd -E -I -i Scripts\InstallCS.sql
Running the Sample
To run the Hello World sample
- Open the scripts\test.sql file in Management Studio. Run the script that is contained in the file, or run the following command in a command prompt window:
sqlcmd -E -I -i Scripts\test.sql
Removing the Sample
To remove the Hello World sample
- Open the scripts\cleanup.sql file in Management Studio. Run the script that is contained in the file, or run the following command in a command prompt window:
sqlcmd -E -I -i Scripts\cleanup.sql
The CLR for SQL Server 2005 or SQL Server Express must be enabled for this sample to work correctly.
Samples are provided for educational purposes only. They are not intended to be used in a production environment and have not been tested in a production environment. Microsoft does not provide technical support for these samples. Sample applications and assemblies
should not be connected to or used with your production SQL Server database or your report server without the permission of the system administrator.
