The Hello World sample demonstrates the basic operations that are involved in creating, deploying, and testing a simple CLR integration-based stored procedure. This sample also demonstrates how to return data via an output parameter and via a record, which is dynamically constructed by the stored procedure and returned to the client.

Prerequisites

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

  • or (SQL Server Express). You can obtain SQL Server Express free of charge from the SQL Server 2005 Express Edition Documentation and Samples Web site

  • The AdventureWorks database, which is included with SQL Server 2005, and is also available at the SQL Server 2005 Express Edition Documentation and Samples Web site.

  • The SQL Server 2005 Database Engine samples. These samples are included with SQL Server 2005 and are also included with the Microsoft Microsoft .NET Framework version 2.0 SDK 2.0.

  • .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

To build the Hello World sample

  1. CD to the install directory and execute the following at a .NET Framework or Microsoft Visual Studio 2005 command prompt:

    sn -k keypair.snk

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

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

  3. Make sure that the AdventureWorks database is installed.

  4. 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.

  5. 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.

  6. 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 and execute the script contained in the file, or execute 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

  1. Open the scripts\test.sql file in SQL Server Management Studio and execute the script contained in the file, or execute the following command in a command prompt window:

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

Removing the Sample

To remove the Hello World sample

  1. Open the scripts\cleanup.sql file in SQL Server Management Studio and execute the script contained in the file, or execute the following command in a command prompt window:

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