title: MS SQL Server Row GUID Column
body: <p>I apologize for asking what seems like a tired question, but no forum response or documentation I've read seems to provide an adequate answer.</p>
  
  <p>What is the purpose of the <code>Row GUID Column</code> property in MS SQL Server 2008?</p>
  
  <p>Let me extend on that. I've seen "Don't use GUID as the PK" repeated as the answer for this question, which seems to be completely unrelated to me. If I set <code>Row GUID Column</code> is it forcing that GUID column to be the primary key or something?</p>
  
  <p>To rephrase my original question: If I have a GUID column in my table that does not play any role in indexing, do I stand to gain anything from setting that GUID column as the <code>Row GUID Column</code>?</p>
