title: Mysql only do not select duplicated values
body: <p>I am looking for a way to run a simple <code>SELECT</code> statment. I have a table which has two columns: <code>id</code> and <code>email</code>.</p>
  
  <p>I want to run a <code>SELECT</code> statment that won't return duplicate values. For example, take the following data:</p>
  
  <pre class="lang-none prettyprint-override"><code>1   example@hotmail.com
  2   example12@hotmail.com
  3   example@hotmail.com
  4   example@hotmail.com
  </code></pre>
  
  <p>I want it to return only the following:</p>
  
  <pre><code>1   example@hotmail.com
  2   example12@hotmail.com
  </code></pre>
  
  <p>...and skip the duplicate values.</p>
