README Execute stored procedure (using ODBC CALL syntax) and process return codes and output parameters (OLE DB)


[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]
This sample works only with SQL Server 2005 and SQL Server "Katmai". It will not work with any version of SQL Server earlier than SQL Server 2005.
This example shows 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 ODBC CALL 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:
*
The SQL Server Database Engine samples. These samples are included with SQL Server. 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 (on some Windows operating systems, you will need to change (localhost) or (local) to the name of your 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.
  • Make sure your INCLUDE environment variable includes the directory that contains sqlncli.h.
  • 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_A.sln file and build it.
    • If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the InitializeAndEstablishConnection_A.sln file: * MSBuild InitializeAndEstablishConnection_A.sln *

    Running the Sample

    • From Visual Studio, invoke Start Without Debugging (CTRL+F5).
    • If you built with MSBuild.exe, invoke InitializeAndEstablishConnection_A.exe. © 2007 Microsoft Corporation. All rights reserved.
