title: Show only every 2nd row after running a WHERE clause
body: <p>I'm trying to show only every 2nd row after selecting something from my DB.</p>
  
  <p>My select looks like this:</p>
  
  <pre><code>SELECT * FROM table where partnerID = '1'
  </code></pre>
  
  <p>Now from the results of that select query I want to get only every 2nd row.</p>
  
  <p>Is that possible ?</p>
