title: Update an image column using a variable
body: <p>I need to copy a value of an image column from one row to another. I tried to use variables for that, but I can't even declare that type of variable. SQL Server returned this error message:</p>
  
  <blockquote>
    <p>Msg 2739, Level 16, State 1, Line 1<br>
    The text, ntext, and image data types are invalid for local variables.</p>
