"IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
'g.promote_price, promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, g.goods_img ' .
"FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.
"LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
"ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.
'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';
