title: How to check if a string is a uniqueidentifier?
body: <p>Is there an equivalent to IsDate or IsNumeric for uniqueidentifier (SQL Server)?
  Or is there anything equivalent to (C#) TryParse?</p>
  
  <p>Otherwise I'll have to write my own function, but I want to make sure I'm not reinventing the wheel.</p>
  
  <p>The scenario I'm trying to cover is the following:</p>
  
  <pre><code>SELECT something FROM table WHERE IsUniqueidentifier(column) = 1
  </code></pre>
