title: Should I ever need to call RTRIM() on a varchar or nvarchar value?
body: <p>I believe the answer to this question is "no" but I'm interested in the community opinion. A varchar or nvarchar value should automatically trim trailing whitespace, so I don't believe I should ever have to call RTRIM() on such a value. Does any expert have a reason that I would need to?</p>
  
  <p>(In case the tags do not make it clear, I'm referring specifically to Microsoft SQL Server.)</p>
