title: Can't send the value of null to MySQL database using Node.JS
body: <p>I'm trying to send <code>null</code> to my MySQL database using Node.JS: 
  </p>
  
  <pre class="lang-js prettyprint-override"><code>con.query("INSERT INTO Routes (routeTrigger) VALUES ( " + null + " )", {title: 'test'}, function(err, result) {
      if (err) throw err;
  });
  </code></pre>
  
  <p>But when looking in the database, the updated value reads <code>'null'</code>. The database's <code>NULL</code> is supposed to read <strong><code>NULL</code></strong>. If I send capital <code>NULL</code> instead, that doesn't even work (in Node.JS). If I send <code>'NULL'</code> it sends the string "NULL", and not the database's <code>NULL</code>.</p>
