title: Oracle - grant privileges to all users
body: <p>I need to grant privileges to all users, I can do:</p>
  
  <pre><code>GRANT select on table TO user1;
  GRANT select on table TO user2;
  ...
  </code></pre>
  
  <p>But there are many users. How can I grant this privilege to all users at once?</p>
  
  <p>I tried:</p>
  
  <pre><code>GRANT select on table TO ALL;
  </code></pre>
  
  <p>But that doesn't work.</p>
