How to store binary image (BLOB) SQL server and load it into QlikView

[ToniKautto]

Storing an image as binary data in an SQL Server and then loading it into QlikView can be done as described in the steps below.

Environment:

• QlikView , all versions

1. Create a table to contain the image as a varbinary or image 
   
   CREATE TABLE ImageAsVarBinary 
   ( 
      ID int IDENTITY(1,1), 
      ImageName varChar(50), 
      varBinaryData varBinary(MAX) 
   );
    
2. Load an image file to the table 
   
   INSERT INTO ImageAsVarBinary (ImageName, varBinaryData) 
   SELECT 'image1', BulkColumn FROM OPENROWSET (Bulk 'C:\Test.jpg', SINGLE_BLOB) AS varBinaryData;
    
3. Load the image to QVW by using an info load 
   
   INFO SQL SELECT
   ImageName, 
   varBinaryData 
   FROM "DB_TABLE_NAME".dbo.ImageAsVarBinary;
    
4. Show the image in an object by setting the field value to
    
   =INFO(ImageName)
    
5. Set the field/object Representation to Image

NOTE: 

• The syntax and SQL example above are based on Microsoft SQL Server 2008, but the principle should be the same on most SQL based database servers.
• For an example of fetching BLOB image from Oracle to QlikView, please refer to the community post at https://community.qlik.com/thread/141239
• See the attached qvw document for a demonstration
