選擇多個和如何按日期正確過濾

Question

這是我目前沒有過濾createdDate的任何內容。

SELECT [employeeID] 
     ,employeeName 
     ,isnull((SELECT SUM(case when clientID != 10 then timeSpent else 0 end)),0) as 'billable' 

     ,isnull((SELECT SUM(case when clientID = 10 then timeSpent else 0 end)),0) as 'nonBillable' 
FROM [myDB].[dbo].[myTable] 
group by employeeID,employeeName 

，其輸出：

employeeID employeeName billable nonbillable 
---------- ------------ -------- ----------- 
1   tom   5230  2302 
2   dick   25  8439 
3   harry  2430  9433 

精確的輸出將是類似的，但僅具有的時間範圍內的值的總和：

employeeID employeeName billable nonbillable 
---------- ------------ -------- ----------- 
1   tom   35  5 
2   dick   25  15 
3   harry  2  48 

[爲myTable]具有以下字段：僱員， employeeName，clientID，timeSpent，createdDate

我需要能夠添加過濾器到eac h選擇總和語句與以下內容類似：WHERE createdDate BETWEEN（'2012-10-01'）AND（'2012-10-07'）

以下變體都會因SQL錯誤或不準確的輸出而失敗：

SELECT [employeeID] 
     ,employeeName 
     ,isnull((SELECT SUM(case when clientID != 10 then timeSpent else 0 end)),0) as 'billable' 
     ,isnull((SELECT SUM(case when clientID = 10 then timeSpent else 0 end)),0) as 'nonBillable' 
FROM [myDB].[dbo].[myTable] 
WHERE createdDate BETWEEN ('2012-10-01') AND ('2012-10-07') 
group by employeeID,employeeName 

SELECT DISTINCT [employeeID] 
     ,employeeName 
     ,isnull((SELECT SUM(case when clientID != 10 then timeSpent else 0 end)),0) as 'billable' 
     ,isnull((SELECT SUM(case when clientID = 10 then timeSpent else 0 end)),0) as 'nonBillable' 
FROM [myDB].[dbo].[myTable] 
WHERE createdDate BETWEEN ('2012-10-01') AND ('2012-10-07') 
group by employeeID,employeeName 

SELECT [employeeID] 
     ,employeeName 
     ,isnull((SELECT SUM(case when clientID != 10 then timeSpent else 0 end)WHERE createdDate BETWEEN ('2012-10-01') AND ('2012-10-07')),0) as 'billable' 
     ,isnull((SELECT SUM(case when clientID = 10 then timeSpent else 0 end)WHERE createdDate BETWEEN ('2012-10-01') AND ('2012-10-07')),0) as 'nonBillable' 
FROM [myDB].[dbo].[myTable] 
group by employeeID,employeeName,createdDate 

任何幫助將不勝感激。

在此先感謝。

第一個查詢應該給你正確的結果

SELECT [employeeID] 
     ,employeeName 
     ,isnull((SELECT SUM(case when clientID != 10 then timeSpent else 0 end)),0) as 'billable' 
     ,isnull((SELECT SUM(case when clientID = 10 then timeSpent else 0 end)),0) as 'nonBillable' 
FROM [myDB].[dbo].[myTable] 
WHERE createdDate BETWEEN '2012-10-01' AND '2012-10-07' 
group by employeeID,employeeName 

但是，如果createdDate是一個日期時間類型，那麼它只會「2012-01-01 00:00」和「2012-2015之間的返回值10-07 00:00' - 2012-10-07 00:01以後沒事了。理想情況下，您可以將過濾日期指定爲日期，而不是字符串。
