title: Remove multiple rows from contentprovider
body: <p>I tried to remove two rows from my content provider with no success.
  Here's the query;</p>
  
  <pre><code>int rowdelted = 
         con.getContentResolver().delete(CONTENT_URI, clausole, null);
  </code></pre>
  
  <p>where clausole is a string like "_ID = 100 AND _ID = 101 AND _ID = 102".</p>
  
  <p>Is there anything wrong?</p>
  
  <p>Thanks in advance</p>
