This is not generally possible. If the varbinary-column contains only the file contents there is no way to get the extension. If i would have designed the database there would be another column describing the filetype/extension. If you know there are only images (as an example) in that column stored you could try to find out by looking for "specific bytes" of jpg, png, etc. files.
