巢狀查詢，巢狀結果

select o.*, u.username, u.address
from orders o,
user u
where o.user_id = u.id
and o.id = #

select u.id,
u.username,
u.address,
o.id order_id,
o.number,
o.createtime,
o.note,
od.id od_id,
od.items_id,
od.items_num,
it.id i_id,
it.name,
it.price,
it.detail
from user u,
orders o,
orderdetail od,
items it
where o.user_id = u.id
and o.id = od.orders_id
and od.items_id = it.id;

解決方法使用巢狀結果，或使用懶載入緩解

@ignore //讓該方法跳過單元測試
