title: Convert month name to month number in SQL Server
body: <p>In T-SQL what is the best way to convert a month name into a number? </p>
  
  <p>E.g:</p>
  
  <pre><code>'January' -&gt; 1
  'February' -&gt; 2
  'March' -&gt; 3
  </code></pre>
  
  <p>Etc.</p>
  
  <p>Are there any built in functions that can do this?</p>
