README How to set large data (OLE DB)

Updated: 17 July 2006
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.


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:
  • SQL Server 2005 or SQL Server 2005 Express Edition (SQL Server Express) including Database Engine. You can download SQL Server Express from the Microsoft Download Center.
  • The AdventureWorks database which is included with SQL Server 2005, and is also available at the Microsoft SQL Server Developer Center.
  • The SQL Server 2005 Database Engine samples. These samples are included with SQL Server 2005. 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. 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.
Adding and deleting the table is done programmatically, in the CreateTable function. If this sample is being run on a computer where the TestISeqStream table has not already been added to the AdventureWorks database, you should comment out the code that deletes the table. If the TestISeqStream table has already been added to the computer database, you should comment out the code that deletes and adds the table.
  • 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 *

Running the Sample

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