Supplementary-Aware String Manipulation
The StringManipulate sample for Microsoft SQL Server 2005 demonstrates supplementary character aware string processing. This sample shows the implementation of five Transact-SQL string functions that provide the same string manipulation functions as built-in ones, but with additional supplementary character-aware capability to handle both Unicode and supplementary character strings. The five functions are len_s(), left_s(), right_s(), sub_s() and replace_s() which equivalent to built-in’s LEN(), LEFT(), RIGHT(), SUBSTRING() and REPLACE() string functions.

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 Web site
The AdventureWorks database which is included with SQL Server 2005, and is also available at the SQL Server Developer Web site.
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 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 SDK.
Ext-B font must be installed on the computer for the correct characters to appear in the SQL Server Management Studio results window. To change the font in the results window, in Management Studio, on the Tools menu, click Options, expand Environment, and then click Fonts and Colors. Set the font to MingLiU_ExtB for Text Results and/or Grid Results. You must close and then reopen Management Studio for the changes to take effect.
If you have not already created the strong-name key file ExternalSampleKey.snk, generate the key file using the following instructions.
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.
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 <system_drive>:\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 following:
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\ StringManipulate.sln
Make sure that the AdventureWorks database is installed, or, if necessary, create the database in which you want to install the samples.
If you did not install the SQL Server Database Engine samples in the default location, modify the path in the CREATE ASSEMBLY part of the script in Scripts\InstallCS.sql and Scripts\InstallVB.sql to refer to location where the samples were installed.
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 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 sample CLR objects into SQL Server.
To run the sample, do the following:
To remove the StringManipulate sample, do the following:
The CLR for SQL Server 2005 or SQL Server Express must be enabled for this sample to work correctly.
