Readme_Setting Large Data (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.

Shows how to set BLOB data, create a table, add a sample record, fetches that record in the rowset, and then set the value of the BLOB field. 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.

For more information on this sample, see How to: Set Large Data (OLE DB) in Books Online.

This sample uses 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.

Adding and deleting the table is done programmatically, in the CreateTable function.

  • If you are using Visual Studio, load the WorkingWithBLOBs.sln file and build it.
  • If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the WorkingWithBLOBs.sln file:
    MSBuild WorkingWithBLOBs.sln

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