合并2行

Question

我有一个看起来像这样的结果集。我想将付费金额相加，并将DTV TOW和FlatBED合并为一行。我有什么方法可以完成吗？

CaseServiceID   PurchaseOrderID PaidAmount  DTV TOW FLATBED
227                 15000227    19.20           1   0
227                 15000227    45.00           0   1

注意：DTV TOW和FLATBED列来自透视表

修改的

Pivot看起来像这样：

select
*
from
(
    select
    cla.CaseServiceID
    ,cla.ServiceTypeProgKey
    ,cla.ClaimAmount
    ,cla.PaidAmount
    ,cla.ClaimQuantity
    from
    Claim cla
) as srcServiceType
pivot
(
    max(ServiceTypeProgKey) for ServiceTypeProgKey in ([FLATBED],[DTV TOW]
) as pvtServiceType

Answer 1

怎么样

SELECT CaseServiceID, 
       PurchaseOrderID, 
       SUM(PaidAmount) PaidAmount,
       SUM([DTV TOW]) [DTV TOW],
       SUM(FLATBED) FLATBED
FROM YourTable
GROUP BY CaseServiceID, PurchaseOrderID

Answer 2

试试这个（假设PaidAmount和ClaimQuantity是位 TinyInt用作布尔值）否则将MAX更改为SUM：

SELECT *
FROM (
    SELECT cla.CaseServiceID,
        cla.ServiceTypeProgKey,
        SUM(cla.ClaimAmount) ClaimAmount,
        MAX(cla.PaidAmount) PaidAmount,
        MAX(cla.ClaimQuantity) ClaimQuantity
    FROM Claim cla
    GROUP BY cla.CaseServiceID,
        cla.ServiceTypeProgKey
    ) AS srcServiceType
pivot(max(ServiceTypeProgKey) FOR ServiceTypeProgKey IN (
            [FLATBED],
            [DTV TOW]
            ) AS pvtServiceType)

Answer 3

查询的最终结果如何。我希望这可以帮助别人。感谢

select
,sum(isnull([FLATBED], 0)) AS [FLATBED]
,sum(isnull([DTV TOW], 0)) AS [DTV TOW]
from
(
    select
    cla.ServiceTypeProgKey,
    ,sum(cla.PaidAmount) as 'PaidAmount'
    ,sum(cla.ClaimQuantity) as 'ClaimQuantity'
    ,sum(cla.PaidQuantity) as 'PaidQuantity'
    from
    Claim cla
    inner join CaseService cse on cla.CaseServiceID = cse.CaseServiceID
    group by cse.PurchaseOrderID
) as srcServiceType
pivot
(
     count(ServiceTypeProgKey) FOR ServiceTypeProgKey IN ([FLATBED],[DTV TOW])
) as pvtServiceType

...和结果

CaseServiceID   PurchaseOrderID   PaidAmount  DTV   TOW FLATBED
227             15000227          64.20       1     1
