Question

I am having trouble trying to render images from an Image column in SQL Server. I got the image data from a client db using straight copy and paste from the grid results, as we had trouble with the export process.

I am aware that there is truncation happening after 65k, but is there any other reason why you can’t copy from one Image column grid data result and paste into another? And if so, is there another way to copy the data apart from Tasks > Export?

Note, when I extract the mime-type from the byte[] array, it comes back as text/plain, so I’m also hoping that there isn’t some special behaviour required by the original coders to treat the data.

Try using a SQL statement to do the update instead:

UPDATE table1
SET table1.Col_Image = (SELECT table2.Col_Image FROM table2 WHERE table2.ID = 2)
FROM table1 
WHERE table1.ID = 1
