SQL Server - 主/详细信息 - 获取精确的详细项目匹配

Question

我需要帮助从两个表中提取确切的项目匹配。我想从详细信息表中查看Temp Detail和Master和Temp Master itemQty中存在的所有顺序是相同的。

示例：在这种情况下，我需要master.Amount的总和，对于ItemQty为3的所有订单，详细信息表具有完全相同的temp Detail值。

主

OrderId|      Amount   | ItemQty |Status
------------------------------------------
125    |       36.75   |    3    |  A    |
------------------------------------------
128    |       11.95   |    5    |  A    |
------------------------------------------

详细信息包含大量订单明细

------------------------------------------
OrderId|  ItemId    |  Qty  | Price      |
------------------------------------------
125    |     12345 |  1   |  11.00      |
------------------------------------------
125    |     23456 |  1   |  12.75      |
------------------------------------------
125    |     34567 |  1   |  13.00      |
------------------------------------------

Temp Master

------------------------------------------
|OrderId|      Amount   | ItemQty |Status
------------------------------------------
|9999   |       36.75   |    3    |  A   |
------------------------------------------

临时详情

------------------------------------------
|OrderId |  ItemId  |  Qty | Price       |
------------------------------------------
| 9999   |   12345 |    1 |   11.00      |
------------------------------------------
| 9999   |   23456 |    1 |   12.75      |
------------------------------------------
| 9999   |   34567 |    1 |   13.00      |
------------------------------------------

提前谢谢

Answer 1

你可以试试这样的东西

select m.OrderId, sum(m.amount)
from master m
join detail d
on m.OrderId = d.OrderId
join tempDetail td
on m.OrderId = td.OrderId
where m.ItemQty = 3
group by m.OrderId
having sum(d.Qty * d.Price) = sum(td.Qty * td.Price)

Answer 2

我最好的猜测：

select Masterr.OrderId,
       sum(Masterr.Amount)
  from Masterr
 where Masterr.ItemQty = 3
   and exists(select *
                from Detail
                join TempMaster on TempMaster.ItemQty = Masterr.ItemQty
                join TempDetail on TempDetail.OrderId = TempMaster.OrderId
               where Detail.OrderId = Masterr.OrderId
                 and TempDetail.ItemId  = Detail.ItemId
                 and TempDetail.Qty     = Detail.Qty
                 and TempDetail.Price   = Detail.Price)
 group by Masterr.OrderId;
