}

this give error
plese corret it or send me as posible as
and also tell me that can we use sqldatareader to store rows

– 0. xp_cmdshell is turned on from sp_configure
sys.sp_configure ‘xp_cmdshell’, 1
RECONFIGURE;

GO
– 1 Declaration
DECLARE @sql VARCHAR(500),
@server sysname,
@user sysname,
@pwd sysname,
@db sysname,
@table sysname,
@column sysname,
@whereclause VARCHAR(500),

– 2. Config
SET @server = @@SERVERNAME
SET @user = ”– input login here
SET @pwd = ”– and pwd
SET @db = DB_NAME()
SET @table = ‘ImageTest’
SET @column = ‘Image’
SET @whereclause = ‘”WHERE ID = 1″‘
SET @filename = ‘ImageFromSQL.jpg’
SET @filepath = ‘C:\tmp\’

– 3. Set textcopy path from path environment variable(manually)
– And set sql string
SET @sql= ‘TextCopy ‘ +
‘ /S ‘ + @server +
‘ /U ‘ + @user +
‘ /P ‘ + @pwd +
‘ /D ‘ + @db +
‘ /T ‘ + @table +
‘ /C ‘ + @column +
‘ /W ‘ + @whereclause +
‘ /F ‘ + @filepath + @filename +
‘ /O ‘ +
‘ /Z ‘ — for debuging

EXEC master..xp_cmdshell @sql –,no_output if wanna see the debug
GO

Let me give you congratulations for having a great honor to take part in Microsoft Global Summit.

I am pleased that I am taking an opportunity to answer in your blog. After reading your blog I felt to create one detail example for same. I just created it on my blog at:

http://ritesh-shah.blogspot.com/2009/03/image-store-in-sql-server-2005-database.html
or
http://riteshshahwordpress.com/2009/03/07/image-store-in-sql-server-2005-database-and-retrieve-it-in-aspnet-application-with-c/

Hope to see you soon and eager to know your experience from your own alluring words by your mouth. However, I get some of that from you blog.

Thanks,

I threw this together real quick, so I know the code can be cleaned up.

The first parameter is the sql query and the second is the output path. Make sure the CLR procedure’s permission level is set to external.

Just want to mention, FILESTREAM in SQL Server 2008 is a cool feature to allocate actual BLOB objects OUTSIDE the database, while keeping reference pointers INSIDE the database
