SQLAuthority News – Author Visit – Toronto, Canada – Insert Image in Database

I am traveling to Toronto from Microsoft MVP Sumeet. I will be very tired as I am continuously working very hard from last 27th Feb. I am still Jet Legged from my trip from India to USA and now I am again changing time zones by visiting Canada. I get all my energy from feeling that what I am doing is helping community and I am working hard to help people who are looking for help.

Interestingly Steven Biggins, a reader of this blog was with me in same flight to Canada. He recognized me and asked me following question. As I have never done this before I had to pull out my laptop in flight and start writing code. Following T-SQL script demonstrates the code which inserts the image in database. You will need small image on your hard drive to create this example. You can download Image and T-SQL Code.

USE [AdventureWorks]
--Create Table
CREATE TABLE [dbo].[ImageTest](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Image] [varbinary](MAX) NULL
--Insert Image
INSERT INTO [dbo].[ImageTest]([Image])
(BULK N'C:\ImageCode\sa.jpg', SINGLE_BLOB) AS Document
--Clean Up DB
DROP TABLE [dbo].[ImageTest]

Now my question to reader is how to retrieve the image and create JPG file again. I will post the solution soon but I rather prefer that the solution provided by my reader.

Following is my travel itinerary so far:

  1. I don’t know if there is any way to do this in T-SQL but the CLR procedure below should do the job.

    using System;
    using System.Data;
    using System.Data.Sql;
    using System.Data.SqlClient;
    using System.Data.SqlTypes;
    using Microsoft.SqlServer.Server;
    using System.IO;

    public partial class StoredProcedures
    public static void usp_RetrieveBlobData(string query,string outpath)
    using(SqlConnection connection = new SqlConnection(“context connection=true”))
    SqlCommand command = new SqlCommand(query, connection);
    SqlDataReader reader = command.ExecuteReader();

    using (reader)
    FileStream fs = File.Create(outpath);
    BinaryWriter bw = new BinaryWriter(fs);

    byte[] file = (byte[])reader.GetSqlBinary(0);



    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.


  2. Hi Pinal,

    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:


    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.
