title: Output of adding an integer and a String in SQL Server
body: <p>I was asked what the following simple query would return.</p>
  
  <pre><code>Select 5 + '4'
  </code></pre>
  
  <p>As, 4 is string type, I expect the query to throw an error. I found I was wrong, tested it, and the result was 9. How does it return the sum?</p>
