[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 2008. It will not work with any version of SQL Server earlier than SQL Server 2008.
This sample uses an ISequentialStream interface bound to an ICommandText parameter to send between 4MB and 4GB of data to a filestream column.
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 on the Filestream feature, see FILESTREAM Support (OLE DB) in Books Online.
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 theMicrosoft Download Center .
-
The AdventureWorks database which is included with SQL Server, and is also available at the
Microsoft SQL Server Developer Center .
-
The SQL Server Database Engine samples. These samples are included with SQL Server. You can download the latest version of the samples 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. See Installing the .NET Framework SDK.
Building the Sample
-
Make sure your INCLUDE environment variable includes the directory that contains sqlncli.h.
-
If you are using Visual Studio, load the ICommandUpload.sln file and build it.
-
If you are using MSBuild.exe, invoke MSBuild.exe at a command prompt, passing it the ICommandUpload.sln file:
MSBuild ICommandUpload.sln
Running the Sample
When you run this sample, you must pass the name of a server, or a server\instance_name, well as a value between 4 MB (0x400001) and 4 GB (0xFFFFFFFF) indicating the amount of data to write.
The server must have a directory called C:\DBFsa; this is where the sample will create the database.
From Visual Studio, invoke Start Without Debugging (CTRL+F5).
If you built with MSBuild.exe, invoke ICommandUpload.exe.
Deleting the Sample Database
To delete the databases in c:\DBFsa, you have to detach the database in SQL Server Management Studio, as follows:
sp_detach_db 'DBFsa' IF EXISTS (SELECT name FROM master..sysdatabases WHERE name = 'DBFsa') DROP DATABASE [DBFsa] |
