title: SELECT from 3rd comma in string
body: <p>I have the following string:</p>
  
  <pre><code>bzip2,1,668,sometext,foo,bar
  </code></pre>
  
  <p>How can I SELECT only <code>sometext,foo,bar</code>? The length of the string preceding the 3rd comma may differ and there may be commas within <code>sometext,foo,bar</code>.</p>
  
  <p>I'd like this in as concise code as possible, i.e. preferably 1 line of code, no loops. But feel free to post any solution you think of.</p>
