Readme_UseDataAtExecutionParameters (ODBC)

11/05/2008 21:36:06


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.
The sample shows how to read SQL_LONG variable character data using SQLParamData and SQLPutData. 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.

Languages

This sample uses Visual C++.

Prerequisites

Before running this sample, make sure the following software is installed:
  • SQL Server or SQL Server Express including Database Engine. You can download SQL Server Express from the Microsoft Download Center.
  • The AdventureWorks database that is available at the Microsoft SQL Server Developer Center.
  • The SQL Server Database Engine samples that are available 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 Documentation.
  • You will also need an ODBC data source called AdventureWorks, whose default database is the AdventureWorks sample database. If you will build and run this sample as a 32-bit application on a 64-bit operating system, you must create the ODBC data source with the ODBC Administrator in %windir%\SysWOW64\odbcad32.exe.

Building the Sample

  • This sample connects to your computer's default SQL Server instance. To connect to a named instance, change the definition of the ODBC data source to specify the instance using the following format: server\namedinstance_. 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
    CREATE TABLE emp4 (NAME char(30), AGE int, BIRTHDAY datetime, Memo1 text) * 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 UseDataAtExecutionParameters.sln file and build it.
    • If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the UseDataAtExecutionParameters.sln file: * MSBuild UseDataAtExecutionParameters.sln *

    Running the Sample

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