The UDTUtilities sample contains a number of utility functions. They include functions to expose assembly metadata to Transact-SQL, sample streaming table-valued functions to return the types in an assembly as a table, and functions to return the fields, methods,
and properties in a user-defined data type. Technologies that are demonstrated include streaming table-valued functions, .NET Framework reflection APIs, and invocation of table-valued functions from Transact-SQL.
When you compile common language runtime (CLR) integration samples, note that the path of the version of the Microsoft .NET Framework compiler that was distributed with SQL Server 2005 must be the first Framework directory in the PATH environment variable.
The location of the compiler that is included with SQL Server 2005 is either
is the installation drive and xxxxx
is the .NET Framework version that is included with your copy of SQL Server 2005.
The default installation directory is drive
:\Program Files\Microsoft SQL Server\90\Samples\Engine\Programmability\CLR\UDTUtilities
A developer would like to access metadata about CLR-based user-defined data types.
Transact-SQL, Visual C#, and Visual Basic.
The UDTUtilities sample uses the following SQL Server 2005 features:
Before you run this sample, make sure the following software is installed:
- SQL Server 2005 or 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 the strong-name key file ExternalSampleKey.snk
, 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 Visual Studio 2005, point to Visual Studio Tools, and then click
Visual Studio 2005 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.
- At the command prompt, use the change directory (CD) command to change the current folder of the command prompt window to the Samples folder.
Note: To determine the folder where samples are located, click Start, 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 <systemdrive_>:\Program Files\Microsoft SQL Server\90\Samples.
- At the command prompt, run the following command to generate the key file:
sn -k ExternalSampleKey.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 sample, do the
Build the 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 the command prompt:
msbuild /nologo /verbosity:quiet /property:Configuration=Debug CS\UDTUtilities.sln
- Ensure that the AdventureWorks database is installed, or, if necessary, create the database in which you want to install the samples.
- 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 script to install and register the utility samples in SQL Server.
Running the Sample
To run the sample, do the following:
Run the sample
- Open the scripts\test.sql file in Management Studio. 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 utility sample objects from Transact-SQL.
Removing the Sample
To remove the sample, do the following:
Remove the sample
- Open the scripts\cleanup.sql file in Management Studio. 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 sample.
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.
