This sample works only with SQL Server 2008. It will not work with any version of SQL Server earlier than SQL Server 2008.
This sample shows how to call SQLColumns on a table with sparse columns that were defined by using ODBC in SQL Server Native Client.
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.

Scenario

For more information about the sparse columns feature, see Sparse Columns Support in SQL Server Native Client in SQL Server Books Online.

Languages

This sample uses Visual C++.

Prerequisites

Before running this sample, make sure that 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 SQL Server Database Engine samples that are available at the Microsoft SQL Server Developer Center.
  • .NET Framework SDK 2.0 (or later) or Microsoft Visual Studio 2005 (or later). You can obtain .NET Framework SDK free of charge. For more information, see Installing the .NET Framework Documentation.

Building the Sample

  • You must specify a server. In odbc_sparse.cpp, change "MyServer" to a valid server name.
  • Make sure your INCLUDE environment variable includes the directory that contains sqlncli.h.
  • If you are using Visual Studio, load the odbc_sparse.sln file and build it.
  • If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt. Pass in the odbc_sparse.sln file, as follows: * MSBuild odbc_sparse.sln *

Running the Sample

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