Scenario

For more information on this sample, see Execute user-defined function and process return code (OLE DB) in Books Online.

Languages

This sample uses Transact-SQL and Visual C++.

Prerequisites

Before running this sample, make sure the following software is installed:
  • SQL Server 2005 or SQL Server 2005 Express Edition (SQL Server Express) including Database Engine. You can download SQL Server Express from the Microsoft Download Center.
  • The AdventureWorks database which is included with SQL Server 2005, and is also available at the Microsoft SQL Server Developer Center.
  • 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 Microsoft SQL Server Developer Center.
  • .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

  • This sample connects to your computer's default SQL Server instance. To connect to a named instance, change the connection string from L"(local)" to L"(local)\name" , where name is the named instance. By default, SQL Server Express installs to a named instance.
  • The sample requires that you add the following user-defined function, which you can find in the sample's scripts directory: * USE AdventureWorks
    drop function fn_RectangleArea
    go

    CREATE FUNCTION fn_RectangleArea
    (@Width int,
    @Height int )
    RETURNS int
    AS
    BEGIN

    RETURN ( @Width * @Height )
    END
    GO * In SQL Server Management Studio, load and execute the Scripts\setup.sql script or execute the following command in a Command Prompt window: * sqlcmd -E -I -i Scripts\setup.sql *
    • If you are using Visual Studio, load the InitializeAndEstablishConnection_C.sln file and build it.
    • If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the InitializeAndEstablishConnection_C.sln file: * MSBuild InitializeAndEstablishConnection_C.sln *

    Running the Sample

    • From Visual Studio, invoke Start Without Debugging (CTRL+F5).
    • If you built with MSBuild.exe, invoke InitializeAndEstablishConnection_C.exe.
