SQL 视图中的运行总计

Question

我试图在 SQL Server 2008 的视图中获取运行总计

这是我的表

BankAccounts
------------
AccountID (KEY)
Name
Created

Transactions
------------
TransactionID (KEY)
Description
Credit
Debit
TransDate
Created
AccountID

这是迄今为止我的查询..

SELECT t.Created, t.Description, t.Credit, t.Debit, t.TransDate, t.TransactionID, ba.AccountID,
        (isnull(t.Credit,0)-isnull(t.Debit,0))+COALESCE((SELECT SUM(isnull(Credit,0)) - SUM(isnull(Debit,0))
                              FROM Transactions b 
                              WHERE b.TransDate < t.TransDate
                               and b.AccountID = t.AccountID),0)
                                 AS RunningTotal
FROM  Transactions t 
INNER JOIN dbo.BankAccounts ba ON t.AccountID = ba.AccountID

我得到的是..

TransDate               Credit                 Debit                  RunningTotal
----------------------- ---------------------- ---------------------- ---------------------
2011-10-08 20:14:00     NULL                   12                     49.25
2011-10-08 20:14:00     2.11                   NULL                   63.36
2011-10-07 20:14:00     42.25                  NULL                   61.25
2011-10-06 20:14:00     NULL                   12.25                  19
2011-10-05 20:14:00     31.25                  NULL                   31.25

它应该是什么样子...

TransDate               Credit                 Debit                  Running Total
----------------------- ---------------------- ---------------------- ---------------------
2011-10-08 00:31:32.957 NULL                   12                     51.36
2011-10-08 00:31:32.957 2.11                   NULL                   63.36
2011-10-07 00:31:32.957 42.25                  NULL                   61.25
2011-10-06 00:31:32.957 NULL                   12.25                  19
2011-10-05 00:31:32.960 31.25                  NULL                   31.25

我真的很接近..只是似乎当同一天有两笔交易时，它没有正确计算..有什么想法吗？

Answer 1

因为您是 2008 年，所以我使用了 ROW_NUMBER 和 CTE

WITH transactionTotal AS
(
   SELECT t.Created, t.Description, t.Credit, t.Debit, t.TransDate, t.TransactionID, a.AccountID
      , ROW_NUMBER() OVER (ORDER BY TransDate ASC) AS RowNumber
      , ( ISNULL(t.Credit, 0) - ISNULL(t.Debit, 0) ) AS TransactionTotal
   FROM dbo.Transactions AS t 
   INNER JOIN dbo.BankAccounts AS a ON t.AccountID = a.AccountID
)
SELECT t.Created, t.Description, t.Credit, t.Debit, t.TransDate, t.TransactionID, t.AccountID
   , ( SELECT SUM(tt.TransactionTotal)
       FROM transactionTotal AS tt
       WHERE tt.RowNumber <= t.RowNumber) AS RunningTotal
FROM transactionTotal AS t
LEFT JOIN transactionTotal AS tt ON t.RowNumber = tt.RowNumber + 1
ORDER BY t.TransDate DESC

Answer 2

SELECT t.Created, t.Description, t.Credit, t.Debit, t.TransDate, t.TransactionID, ba.AccountID,
       coalesce((select sum(ISNULL(Credit,0) - ISNULL(Debit, 0)) 
                 from Transactions
                 where TransactionID <= t.TransactionID and 
                       AccountID = ba.AccountID and
                      convert(date, TransDate) = convert(date, t.TransDate)),0)
        AS [Running Total]

FROM  Transactions t INNER JOIN
         dbo.BankAccounts ba ON t.AccountID = ba.AccountID

--我将使用现有的身份列来 100% 确定我正在处理正确的事务。

SELECT t.Created, t.Description, t.Credit, t.Debit, t.TransDate, t.TransactionID, ba.AccountID,
        (isnull(t.Credit,0)-isnull(t.Debit,0))+COALESCE((SELECT SUM(isnull(Credit,0)) - SUM(isnull(Debit,0))
                              FROM Transactions b 
                              WHERE b.TransactionID < t.TransactionID 
                               and b.AccountID = t.AccountID),0)
                                 AS RunningTotal
FROM  Transactions t 
INNER JOIN dbo.BankAccounts ba ON t.AccountID = ba.AccountID

--此外，如果将“小于”更改为“小于或等于”，则不必添加当前项目：

SELECT t.Created, t.Description, t.Credit, t.Debit, t.TransDate, t.TransactionID, ba.AccountID,
COALESCE((SELECT SUM(isnull(Credit,0)) - SUM(isnull(Debit,0))
                              FROM Transactions b 
                              WHERE b.TransactionID <= t.TransactionID  
                               and b.AccountID = t.AccountID),0)
                                 AS RunningTotal
FROM  Transactions t 
INNER JOIN dbo.BankAccounts ba ON t.AccountID = ba.AccountID

总计应为：（假设）起始余额：49.25

TransDate               Credit            Debit          RunningTotal      
----------------------- ----------------- -------------- ----------------- 
2011-10-08 20:14:00     NULL              12             37.25 
2011-10-08 20:14:00     2.11              NULL           39.36            
2011-10-07 20:14:00     42.25             NULL           81.61
2011-10-06 20:14:00     NULL              12.25          69.36
2011-10-05 20:14:00     31.25             NULL           100.61

Answer 4

如果这是Oracle，那么就有窗口函数。您可以使用 LEAD 和/或 LAG 对当前行相对于之前或即将到来的行执行计算（基于排序顺序）

Answer 5

我正在尝试将这个逻辑与上面的 RowNumber 和 CTE 一起使用。在我的场景中，我需要计算两个字段的组合的运行总计：SalesProdLineID 和 FiscYerPer。这是我编码的内容（在本例中，由于基础表的大小，我将结果限制为单个月份：

 WITH RunningTotal AS
(
   SELECT to2PN.CompanyID, REPLACE(SP.SalesProdLineID, ' Sls PL','') AS SlsPL, vo2PNQtyProd.QtyProdStock,  FP.FiscYearPer, FP.FiscPer, FP.FiscYear
      , ROW_NUMBER() OVER (ORDER BY SP.SalesProdLineID,FP.FiscYearPer  ASC) AS RowNumber
      , ( ISNULL(vo2PNQtyProd.QtyProdStock, 0)  ) AS RunningTotal
   FROM to2PN  (NOLOCK)
 JOIN to2PNProdTempl   (NOLOCK)
     ON to2PN.PNKey = to2PNProdTempl.PNKey
JOIN timItem I  (NOLOCK)
    ON to2PNProdTempl.ItemKey = I.ItemKey
 JOIN timSalesProdLine SP (NOLOCK)
    ON I.SalesProdLineKey = SP.SalesProdLineKey
 JOIN vo2PNQtyProd   (NOLOCK)
     ON to2PNProdTempl.PNProdTemplKey=vo2PNQtyProd.PNProdTemplKey
 JOIN tglFiscalPeriod FP (NOLOCK)
    ON I.CompanyID = FP.CompanyID
        AND to2PN.ComplDateTime BETWEEN FP.StartDate AND Fp.EndDate
WHERE I.ItemID BETWEEN '0000-0' AND '1999-9'
    AND YEAR(to2PN.[ComplDateTime]) = '2018'    --  !! COMMENT OUT for final
    AND MONTH(to2PN.[ComplDateTime]) = 5    --  !! COMMENT OUT for final
)
SELECT t.CompanyID, t.SlsPL, t.QtyProdStock, t.FiscYearPer, t.FiscPer, t.FiscYear
   , ( SELECT SUM(tt.RunningTotal)
       FROM RunningTotal AS tt
       WHERE tt.RowNumber <= t.RowNumber) AS RunningTotal
FROM RunningTotal AS t
LEFT JOIN RunningTotal AS tt ON t.RowNumber = tt.RowNumber + 1
ORDER BY t.FiscYearPer DESC

问题是，一旦获得第一个 SalesProdLineID 的正确总计，它只是将运行总计添加到下一个销售产品线 ID。
