Readme_Stored Procedure Using ODBC CALL Syntax (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 2008. 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.

SQL Server samples and sample databases must be downloaded and installed before you can view or work with them. For more information, see Considerations for Installing SQL Server Samples and Sample Databases.

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

Before running this sample, make sure the following software is installed:

  • 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
    

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