	mysqli_stmt_execute($this->Query_ID) ; 
	
      # Will return nada if it fails. That's fine.
      return $this->Query_ID;
  }
}

Test script:
---------------
$db  = new DB($DBArray);
$db->query("select * from xyz");  // This is working fine.

$db->Link_ID=0;
$db->query("select * from abc");  // This is not working. I can not get any value of the column. 

Please Note : above code is already working fine in 5.4.
By Testing we found that after remove @mysqli_stmt_free_result($this->Query_ID); line from free function, code is running properly.But for not all the sections.

Please advice on this asap
