Demonstrates processing a rowset, a return code, and an output parameter. This sample is not supported on IA64.

Scenario

For more information on this sample, see How to: Execute a Stored Procedure (Using RPC Syntax) and Process Return Codes and Output Parameters (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 you to execute the following stored procedure, which you can find in the sample's scripts directory:

  USE AdventureWorks
  DROP PROCEDURE myProc
  GO
  
  CREATE PROCEDURE myProc 
      @inparam nvarchar(5),
      @outparam int OUTPUT
  
  AS
  SELECT Color, ListPrice 
  FROM Production.Product WHERE Size > @inparam
  SELECT @outparam = 100
  
  IF  (@outparam > 0)
      RETURN 999
  ELSE
      RETURN 888
  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_B.sln file and build it.

• If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the InitializeAndEstablishConnection_B.sln file:

  MSBuild InitializeAndEstablishConnection_B.sln
  

Running the Sample

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