title: How to list all grants of select, insert, delete or update for a user
body: <p>DB: Oracle 10g</p>
  
  <p>I can grant DML commands to a user for some tables:</p>
  
  <pre><code>GRANT SELECT, UPDATE, DELETE, INSERT ON USER_A.TABLE_1 TO USER_B;
  </code></pre>
  
  <p>How to list all grants (about select, update, insert, delete) that USER_B has received, and for what tables?</p>
  
  <p>I checked table "all_tab_privs_recd", but doesn't have what I'm looking for.</p>
