Empty set but has a result

[nebulom]

I have a weird problem. The query seems to be empty but I got a result resource.

$query = 'SELECT ...';
		print_r($this->db . '<br>');
		$result = mysql_query($query, $this->db);
		print_r($result);
		if ($result) {
			$price_max_schedules = mysql_result($result, 0, "value");
		}

Outputs:

Resource id #72
Resource id #97

I know I'm missing something but I can't seem to find it. Help anyone? Thanks in advance!
