title: Check if data is included in SQLite3 database with node.js
body: <p>So i want to check if some kind of text data is in my database with node.js</p>
  
  <pre><code>if(db.run("message.author.username IN (participations|name)")) {
      db.run("INSERT INTO participations(name, info) VALUES (?, ?)", [message.author.username, message.content]);
      message.author.send("Teilnahme bestätigt!");
  } else {
      message.author.send("Du nimmst schon teil!");
  };
  </code></pre>
  
  <p>The <code>if()..</code> part isnt working, everything else without <code>if()</code> is working too.
  Is there a way to use that properly?</p>
