title: PHP Select multiple desc limit's?
body: <p>In my sql table i had more then 300000 entries.</p>
  
  <pre><code> $marketname = more then 200 !
  </code></pre>
  
  <p>with this select i can see the last 15 entries.</p>
  
  <pre><code>$sql = "SELECT price FROM markets where market = '" . $marketname . "' order by time desc LIMIT 15,1";
  $sql = "SELECT price FROM markets where market = '" . $marketname . "' order by time desc LIMIT 15,1";
  </code></pre>
  
  <p>and so on for the last 30, 60, 120.</p>
  
  <pre><code>$sql = "SELECT price FROM markets where market = '" . $marketname . "' order by time desc LIMIT 30,1";
  $sql = "SELECT price FROM markets where market = '" . $marketname . "' order by time desc LIMIT 60,1";
  </code></pre>
  
  <p>But is there a combination of all, because when i show it on one page its very very slow with 200 markets!!</p>
  
  <p>like.. </p>
  
  <pre><code>$sql = "SELECT price FROM markets where market = '" . $marketname . "' order by time desc LIMIT 15,1 AND LIMIT 30,1 AND LIMIT 60,1 AND LIMIT 120,1";
  </code></pre>
