我需要一些关于计算跑步余额的帮助。下面是表格D009040的输出。

我想计算借方和贷方分录，并获得每个日期的运行余额。我使用以下查询。

SELECT CM.LBrCode, CM.MainAcctId, CM.EntryDate,
       sum(CASE WHEN CM.DrCr='C' THEN CM.FcyTrnAmt
                WHEN CM.DrCr='D' THEN CM.FcyTrnAmt * -1 END)
           OVER (PARTITION BY CM.MainAcctId ORDER BY CM.SetNo) As Amount, 
       sum(CASE WHEN CM.DrCr='C' THEN CM.FcyTrnAmt
                WHEN CM.DrCr='D' THEN CM.FcyTrnAmt * -1 END)
           OVER (PARTITION BY CM.MainAcctId ORDER BY CM.SetNo) As Amount
FROM D009040 CM

它会计算运行余额，但如果同一天有两笔交易，则会计算并显示两笔余额。我的要求是，如果同一天有两笔交易，那么请借记或贷记，并显示该日期的单一最新余额。

我对如何做到这一点有任何想法？

可能是这样的：

; WITH Base AS
(
    SELECT MIN(CM.LBrCode) LBrCode,
           CM.MainAcctId,
           CM.EntryDate,
           MIN(CM.SetNo) SetNo,
           SUM(CASE
             WHEN CM.DrCr = 'C' THEN CM.FcyTrnAmt
             WHEN CM.DrCr = 'D' THEN CM.FcyTrnAmt * -1
           END) FcyTrnAmt
    FROM   #D009040 CM
    GROUP BY CM.MainAcctId, CM.EntryDate
)

SELECT B.LBrCode,
       B.MainAcctId,
       B.EntryDate,
       B.FcyTrnAmt,
       SUM(B.FcyTrnAmt) OVER (PARTITION BY B.MainAcctId ORDER BY B.SetNo) Balance
       FROM Base B

我首先在Base计算当天的总动作，然后在第二个SELECT中计算总计。请注意，我不太喜欢第一个SELECT按EntryDate分组的事实（因此给予＆＃34;日期＆＃34;最重要的操作），而第二个SELECT是ORDER BY SetNo，这是因为第一个操作可以/会使某些SetNo＆＃34;消失＆＃34; （MIN(CM.SetNo)）

计算期初余额
