title: Error setting newsequentialid() default in sql server 2008
body: <p>I have a uniqueidentifier column in a table and it's not a key or index. I want to set the default value using NEWSEQUENTIALID(), but I get the error:</p>
  
  <blockquote>
    <p>Error validating default for column..</p>
  </blockquote>
  
  <p>But if I use NEWID() no error. What's going on?</p>
  
  <p>EDIT: you can just ignore the error dialog and continue.</p>
