$query_options = array();
$query_options['fields'] = array( 'pp.product_properties_id', 'ppv.product_property_value_id' );
$query_options['conditions'] = array( 'pp.property_name' => 'Color' , 'ppv.properties_value' => 'Blue');
$query_options['joins'] = array('table' => 'product_property_values',
                                    'alias' => 'ppv',
                                    'type' => 'INNER',
                                    'conditions' => array(
                                        'ppv.id = pp.ppv_id',
                                    )
                                );

$result = $this->pp->find('all', $query_options);
