title: MySQL online testing tool
body: <p>is there an online tool for MySQL (or just SQL) that lets me quickly test some ideas that come to my mind randomly?</p>
  
  <p>Like JSFiddle for HTML/CSS/JS
  Or <a href="http://writecodeonline.com/php/">http://writecodeonline.com/php/</a> for PHP?</p>
  
  <p>Something like this but for MySQL.</p>
  
  <p>Thanks in advance.</p>
