选择多个总和如何正确按日期过滤

Question

这是我目前没有按 createdDate 过滤任何内容的内容。

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

哪个输出：

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

准确的输出将是相似的，但值的总和仅在日期范围内：

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

[myTable] 有以下字段：employeeID,employeeName,clientID,timeSpent,createdDate

我需要能够在每个 select sum 语句中添加一个过滤器，类似于以下内容：WHERE createdDate BETWEEN ('2012-10-01') AND ('2012-10-07')

以下变体均因 SQL 错误或输出不准确而失败：

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

任何帮助将不胜感激。

提前致谢。

第一个查询应该会给你正确的结果

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 是日期时间类型，则它只会返回 '2012-01-01 00:00' 和 '2012-10-07 00:00' 之间的值 - 2012-10-07 之后没有任何值00:01。理想情况下，您可以将过滤日期指定为日期，而不是字符串。
