Uploading Docs Into Sql Server

[Guest]

Can someone offer or point me to some sample code or advice on how to upload a document from a web page and store it into a SQL Server image field? And then reverse the process and serve up the file from the database when requested through a web page...

Thanks.

Google is your friend - there are loads of articles and code samples
available:

Jerry,

1. Uploading is simple for the actual file uploading piece.

Use the <asp:htmlfileinput /> control and when the page posts use the
..PostedFile.SaveAs(stream) method to save it. Use a SqlCommand and add
a parameter, set it's type to SqlDbType.Image.

2. Retrieving the data is relatively simple, fill your dataset and
extract the column as you would any other column. Cast it to whatever
you need...

variable = (byte[])dataset.Tables[0][x];

Hi Jerry,

For Uploading file in ASP.NET, there are many tech article describing this:

#How to upload a file to a Web server in ASP.NET by using Visual Basic .NET
http://support.microsoft.com/kb/323245/en-us

#ASP.NET 2.0 FileUpload Server Control
http://www.codeguru.com/dbfiles/get_avatar.php?id=183439

Also, the following article has demonstrate store the uploaded file content
into database binary data table column:

#File Upload with ASP.NET
http://www.codeproject.com/aspnet/fileupload.asp


In addition, for reading and retrieveing binary/image data in SQL Server,
they're pure ADO.NET data accessing tasks and here are some good article
demonstrate this:


#Storing and Retrieving Images from SQL Server using Microsoft .NET
http://www.codeproject.com/cs/database/ImageSaveInDataBase.asp

#Utilize ADO.NET and C# to work with BLOB data
http://builder.com.com/5100-6371_14-5766889.html


Hope this helps.

Sincerely,
