title: What does the pipe operator do in SQL?
body: <p>I am redeveloping an application and have found this sql statement, what does the <code>|</code> character do in this part <code>(au.ExNetBits | 8)</code>, I haven't seen before and can't find any answer online?</p>
  
  <p><code>
  SELECT au.AccountID,au.ExNetBits FROM AccountUser au (NOLOCK)<br />
  WHERE au.CDAGUserId=102  and <strong>(au.ExNetBits | 8)</strong> = au.ExNetBits</code></p>
