title: How to get a cursor with distinct values only?
body: <p>I want to return a cursor only with distinct values of a column.
  The column 'Groups' has more items but with only 2 values: 1,2,1,1,1,2,2,2,1 </p>
  
  <pre><code>String[] FROM = {Groups,_ID};
  
  public Cursor getGroups(){
  //......
  return db.query(TABLE_NAME,FROM,null,null,null,null,null);
  }
  </code></pre>
  
  <p>will return a cursor containing {1,2,1,1,1,2,2,2,1} but I would like to contain just {1,2}.</p>
