title: What is the string length of a GUID?
body: <p>I want to create a varchar column in SQL that should contain <code>N'guid'</code> while <code>guid</code> is a generated GUID by .NET (<a href="https://docs.microsoft.com/en-us/dotnet/api/system.guid.newguid" rel="noreferrer">Guid.NewGuid</a>) - class System.Guid.</p>
  
  <p>What is the length of the <code>varchar</code> I should expect from a GUID?
  Is it a static length?</p>
  
  <p>Should I use <code>nvarchar</code> (will GUID ever use Unicode characters)?</p>
  
  <pre><code>varchar(Guid.Length)
  </code></pre>
  
  <p>PS. I don't want to use a SQL row guid data-type. I am just asking what is <code>Guid.MaxLength</code>.</p>
