sql-server - SQL Server 使用 Group by 和 union 选择查询

Question

我在 SQL Server 中有两个表，它们都有相同的列:

• GenerateTicket - 用于按票号归还服装
• GenerateTicket_Return - 用于通过使用 costumeid 或名称(批量)返回服装

查询

select 
    Temp.CostumeName, temp.costumetotalprice, 
    Temp.Quantity, Temp.RQty, 
    Temp.Quantity - temp.rqty  as PendingQty,
    Temp.refund * Temp.Quantity as refund,
    Temp.REFUNDED, 
    temp.costumetotalprice - temp.REFUNDED  as TotalAmount 
from 
    (select 
         sum(costumetotalprice) as costumetotalprice,  
         sum(CostumeQuantity) as Quantity,
         c.refundamount as refund,
         sum(ISNULL(b.RefundAmount, 0)) as REFUNDED,
         (select sum(ISNULL(CostumeQuantity, 0)) 
          from GenerateTicket 
          where CostumeCode = b.CostumeCode 
            and IsRefund = 0 
            and RefundAmount <> 0.00) as RQty,
         (select sum(ISNULL(CostumeQuantity, 0)) 
          from GenerateTicket 
          where CostumeCode = b.CostumeCode 
            and IsRefund = 1 
            and RefundAmount = 0.00) as PendingQty,
          sum(ISNULL(CostumeTotalPrice, 0) - ISNULL(b.RefundAmount, 0)) as TotalAmount,
          c.CostumeName 
      from 
          GenerateTicket as b 
      inner join 
          MasterCostume as c on b.costumecode = c.ID
      where 
          1 = 1  
      group by 
          c.CostumeName, b.CostumeCode, c.refundamount 

     union  

     select 
         sum(costumetotalprice) as costumetotalprice,  
         sum(CostumeQuantity) As Quantity,
         c.refundamount as refund,
         sum(ISNULL(b.RefundAmount,0)) as REFUNDED,
         (select sum(ISNULL(CostumeQuantity, 0)) 
          from GenerateTicket 
          where CostumeCode = b.CostumeCode 
            and IsRefund = 0 
            and RefundAmount<>0.00) as RQty,
         (select sum(ISNULL(CostumeQuantity, 0)) 
          from GenerateTicket 
          where CostumeCode = b.CostumeCode 
            and IsRefund = 1 
            and RefundAmount = 0.00) as PendingQty ,
         sum(ISNULL(CostumeTotalPrice, 0) - ISNULL(b.RefundAmount, 0)) as TotalAmount,
         c.CostumeName 
     from 
         GenerateTicket_Return as b 
     inner join 
         MasterCostume as c on b.costumecode = c.ID
     where 
         1 = 1  
     group by 
         c.CostumeName,b.CostumeCode,c.refundamount) Temp

但问题是我得到了一些像这样的重复数据:

只使用子查询

select CostumeName,costumetotalprice,Quantity,PendingQty,sum(refund) as refund,sum(REFUNDED) as REFUNDED,sum(TotalAmount) as TotalAmount from
    (
    select 
        Temp.CostumeName, temp.costumetotalprice, 
        Temp.Quantity, Temp.RQty, 
        Temp.Quantity - temp.rqty  as PendingQty,
        Temp.refund * Temp.Quantity as refund,
        Temp.REFUNDED, 
        temp.costumetotalprice - temp.REFUNDED  as TotalAmount

        (select 
             sum(costumetotalprice) as costumetotalprice,
