title: SQL Server 2008 Converting VARCHAR(50) to Uniqueidentifier
body: <p>I'm trying to convert a varchar(50) column to a uniqueidentifier, but this error keeps popping up all the time, and i don't know why:</p>
  
  <pre><code>"Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier."
  </code></pre>
  
  <p>The data in the column is currently a valid uniqueidentifier.</p>
  
  <p>What's the proper way of doing what I want?</p>
  
  <p>Thanks</p>
