每种类型的最大日期和最新付款金额

Question

我无法将数据限制为仅一行，最后一次付款和根据每种类型的最后日期对每个帐户进行的调整。

请注意，付款和调整可能在同一天进行，也可能只有其中一部分。因此，我需要这两种类型的最后日期和最后金额。

    select 
      BV.AccountNumber,
      BV.VisitID,

     MAX(case when Type='R'  then FORMAT(BCT.BatchDateTime,'MM/dd/yyyy') END) as 'PaymentDate',
    (case when TransactionProcedureID like 'P%' then BCT.Amount END) as 'PaymentAmount',
      max(case when Type='A' then FORMAT(BCT.BatchDateTime,'MM/dd/yyyy') END) as 'AdjustmentDate',
      (case when TransactionProcedureID like 'A%' then BCT.Amount END) as 'PaymentAmount'


    From BarVisits  BV
         JOIN BarCollectionTransactions BCT ON BCT.SourceID = BV.SourceID AND BCT.VisitID = BV.VisitID and BCT.BillingID =BV.BillingID 

     WHERE  
      AccountNumber IN ('123456789')

    group by 
            BV.AccountNumber
            ,BV.VisitID
            ,BCT.TransactionProcedureID 
            ,BCT.Amount

截至目前的结果

VisitID           PaymentDate       PaymentAmount      AdjustmentDate   PaymentAmount
12345             NULL              NULL               05/08/2020     -4471.73
12345             NULL              NULL               04/03/2020     -4286.15
12345             NULL              NULL               04/23/2020     -381.70
12345             NULL              NULL               04/23/2020       381.70
12345             02/24/2020        -90.00             NULL             NULL
12345             04/03/2020        -392.40            NULL             NULL
12345             05/08/2020        -196.12            NULL             NULL

我需要查看的结果

VisitID           PaymentDate       PaymentAmount      AdjustmentDate   PaymentAmount
12345             05/08/2020        -196.12            05/08/2020      -4471.73

Answer 1

嗯。 。 。您似乎想过滤到最近的日期，然后使用条件聚合：

select bct.VisitID, 
       max(case when type = 'R' then bct.BatchDateTime end) as r_BatchDateTime,
       max(case when type = 'A' then bct.amount end) as a_amount
       max(case when type = 'R' then bct.BatchDateTime end) as a_BatchDateTime,
       max(case when type = 'A' then bct.amount end) as a_amount
from BarVisits bv join
     (select bct.*,
             row_number() over (partition by bct.VisitID, bct.type order by bct.BatchDateTime desc) as seqnum
      from BarCollectionTransactions bct
     ) bct
     on bv.VisitID = bct.VisitID
where bv.AccountNumber in ('123456789') and seqnum = 1;
group by bct.VisitID;

此日期仅包含一次，因为根据定义它是相同的。
