正在運行總共SQL服務器 - AGAIN

我知道這個問題已被多次詢問，並且我已經閱讀過這些線程以獲得我現在的位置，但這些解決方案似乎沒有工作。我需要有一個運行總和我ExpectedAmount的...正在運行總共SQL服務器 - AGAIN

我有如下表：

+--------------+----------------+ 
| ExpectedDate | ExpectedAmount | 
+--------------+----------------+ 
|   1 |  2485513 |

我有以下SQL：

SELECT a.ExpectedDate, a.ExpectedAmount, (SELECT SUM(b.ExpectedAmount) 
         FROM UnpaidManagement..Expected b 
         WHERE b.ExpectedDate <= a.ExpectedDate) 
FROM UnpaidManagement..Expected a

上面的SQL的結果是這個：

你可以從前面的幾個值已經知道，數學是全部關閉，但然後在s ome分數加起來？！我太困惑了！有人可以請我指出另一種解決方案，或者我在哪裏出錯了？

我使用SQL Server 2008的

這是因爲varchar類型的ExpectedDate列。試試這個：

SELECT a.ExpectedDate, a.ExpectedAmount, (SELECT SUM(b.ExpectedAmount) 
         FROM UnpaidManagement..Expected b 
         WHERE CAST(b.ExpectedDate as int) <= CAST(a.ExpectedDate as int)) 
FROM UnpaidManagement..Expected a

請注意，它可能是低效的查詢。

噢你CHAMP！這確實是VARCHAR，是呀！非常感謝...這整理出來。 – Mike

我認爲這會工作：

SELECT a.ExpectedDate, 
     a.ExpectedAmount, 
     SUM(b.ExpectedAmount) RuningTotal 
FROM UnpaidManagement..Expected a 
LEFT JOIN UnpaidManagement..Expected b 
    ON CAST(b.ExpectedDate as int) <= CAST(a.ExpectedDate as int) 
GROUP BY a.ExpectedDate, a.ExpectedAmount

AND：

SELECT a.ExpectedDate, 
     a.ExpectedAmount, 
     c.RuningTotal 
FROM UnpaidManagement..Expected a 
CROSS APPLY (
    SELECT SUM(b.ExpectedAmount) AS RuningTotal 
    FROM UnpaidManagement..Expected b 
    WHERE CAST(b.ExpectedDate as int) <= CAST(a.ExpectedDate as int) 
) c
