body: <p>How do I revoke all privileges for a user in SQLPlus?
  I'm logged in as <code>sysdba</code> and I would like to revoke all privileges for a regular user.</p>
  <p>I googled this query</p>
  <pre><code>REVOKE ALL PRIVILEGES, GRANT OPTION FROM user [, user] ...
  </code></pre>
  <p>but I don't understand what should I put for user, etc.</p>
