title: Hidden Features of MySQL
body: <p>I've been working with <a href="http://www.microsoft.com/Sqlserver/" rel="nofollow noreferrer">Microsoft SQL Server</a> with many years now but have only just recently started to use <a href="http://www.mysql.com/" rel="nofollow noreferrer">MySQL</a> with my web applications, and I'm hungry for knowledge.</p>
  
  <p>To continue with the long line of <a href="https://stackoverflow.com/questions/tagged/hidden-features">"hidden feature" questions</a>, I would like to know any hidden or handy features of MySQL which will hopefully improve my knowledge of this open source database.</p>
