我正在使用ASP.NET（C＃）GridView和带有Sql Server后端的模板字段来处理时间表报告应用程序。我基本上抓住员工一周的任务列表，使用RowDataBound循环访问GridView并检查EndTime是否落在Sun - Sat上，然后将那些小时/分钟放在该列标签中。您可以在下面看到我的GridView标题的示例（抱歉格式化）。
类型|小时|分钟|开始时间|结束时间|太阳|周一|周二|周三|周四|周五|周六|总计
问题是我的groupby没有将我的任务分组在一起，因为我的StartTime / EndTimes将是唯一的，但我需要将它们拉回来，以便我可以检查它属于哪一天，然后填充该列（如您所见）它返回的两行）。我想可能有一种方法可以创建第二个GridView并根据第一个Gridview中的某些值填充它。有没有其他人偶然发现这样的问题？
SELECT
C.Task,
CONVERT(VARCHAR(10), A.StartTime, 101) As StartTime,
CONVERT(VARCHAR(10), A.EndTime, 101) As EndTime,
SUM(DATEDIFF(n, A.StartTime, A.EndTime)) / 60 AS Hours,
SUM(DATEDIFF(n, A.StartTime, A.EndTime)) % 60 AS Minutes
FROM dbo.Timesheet A, dbo.Employees B,
dbo.TimeSheet_Master C
WHERE A.CreatedBy = B.ContactId
AND A.Task = C.Task
AND (B.ContactId =@ContactId)
AND (A.StartTime >= @StartTime)
AND (A.EndTime <= @EndTime)
GROUP BY CONVERT(VARCHAR(10), A.StartTime, 101), CONVERT(VARCHAR(10), A.EndTime, 101), C.Task;
Task StartTime EndTime Hours Minutes

您需要的是按周分组。查看here以获取完整解决方案，如果您需要有关完整解决方案的帮助，请告诉我们。

我不是100％确定您的要求是什么，但这几乎就像您想要组合一个数据透视表。
我很快就这样做了，所以它可能不太适合你的需要，但无论如何......
我创建了一个名为#timesheet的临时表，并添加了一些值：
CREATE TABLE #timesheet
(
Task VARCHAR(10),
employee INT,
StartDate DATETIME,
endDate DATETIME
)
INSERT INTO #timesheet (Task, employee, StartDate, endDate) VALUES ('Task1',10,'2011-5-10 17:00:00','2011-5-10 20:00:00' )
INSERT INTO #timesheet (Task, employee, StartDate, endDate) VALUES ('Task1', 10, '2011-5-12 17:00:00', '2011-5-12 20:00:00' )
INSERT INTO #timesheet (Task, employee, StartDate, endDate) VALUES ('Task2',10,'2011-5-12 17:00:00','2011-5-12 20:00:00' )
INSERT INTO #timesheet (Task, employee, StartDate, endDate) VALUES ('Task1', 12, '2011-5-08 17:00:00', '2011-5-08 20:00:00' )
我创建了一个取自Kodyaz Development Services的GetWeekDayNameOfDate函数来获取星期几。
我首先创建了一个摘要查询，如下所示：
SELECT #timesheet.Task,
#timesheet.employee,
MIN(#timesheet.StartDate) AS [Start Date],
MAX(#timesheet.endDate) AS [End Date],
SUM(DATEDIFF(n, #timesheet.StartDate, #timesheet.endDate)) / 60 AS [Hours],
SUM(DATEDIFF(n, #timesheet.StartDate, #timesheet.endDate)) % 60 AS [Minutes]
FROM #timesheet
GROUP BY #timesheet.Task,
#timesheet.employee
这会给我我对任务和员工的总结。它将显示整个持续时间的开始日期和结束日期以及小时数和分钟数。
我的结果将是：
Task employee Start Date End Date Hours Minutes
---------- ----------- ----------------------- ----------------------- ----------- -----------
Task1 10 2011-05-10 17:00:00.000 2011-05-12 20:00:00.000 6 0
Task2 10 2011-05-12 17:00:00.000 2011-05-12 20:00:00.000 3 0
Task1 12 2011-05-08 17:00:00.000 2011-05-08 20:00:00.000 3 0
我接下来创建了一个详细信息数据透视查询，以总结一周中每一天所花费的小时数。
SELECT Task,
Employee,
ISNULL([Sunday], 0) AS Sunday,
ISNULL([Monday], 0) AS Monday,
ISNULL([Tuesday], 0) AS Tuesday,
ISNULL([Wednesday], 0) AS Wendesday,
ISNULL([Thursday], 0) AS Thursday,
ISNULL([Friday], 0) AS Friday,
ISNULL([Saturday], 0) AS Saturday
FROM ( SELECT #timesheet.Task,
#timesheet.employee,
dbo.GetWeekDayNameOfDate(#timesheet.StartDate) AS [Day],
SUM(DATEDIFF(n, #timesheet.StartDate, #timesheet.endDate))
/ 60 AS [Hours],
SUM(DATEDIFF(n, #timesheet.StartDate, #timesheet.endDate))
% 60 AS [Minutes]
FROM #timesheet
GROUP BY #timesheet.Task,
#timesheet.employee,
dbo.GetWeekDayNameOfDate(#timesheet.StartDate)
) p PIVOT ( SUM(Hours) FOR [DAY] IN ( [Sunday], [Monday], [Tuesday],
[Wednesday], [Thursday],
[Friday], [Saturday] ) ) AS PivotTable
我的结果将是：
Task Employee Sunday Monday Tuesday Wendesday Thursday Friday Saturday
---------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- -----------
Task1 10 0 0 3 0 3 0 0
Task1 12 3 0 0 0 0 0 0
Task2 10 0 0 0 0 3 0 0
Aftwards我一起加入了我的两个问题以获得整个图片
SELECT summary.Task,
summary.employee,
summary.[Start Date],
summary.[End Date],
details.Sunday,
details.Monday,
details.Tuesday,
details.Wendesday,
details.Thursday,
details.Friday,
details.Saturday,
summary.Hours,
summary.Minutes
FROM ( SELECT #timesheet.Task,
#timesheet.employee,
MIN(#timesheet.StartDate) AS [Start Date],
MAX(#timesheet.endDate) AS [End Date],
SUM(DATEDIFF(n, #timesheet.StartDate, #timesheet.endDate))
/ 60 AS [Hours],
SUM(DATEDIFF(n, #timesheet.StartDate, #timesheet.endDate))
% 60 AS [Minutes]
FROM #timesheet
GROUP BY #timesheet.Task,
#timesheet.employee
) summary
INNER JOIN ( SELECT Task,
Employee,
ISNULL([Sunday], 0) AS Sunday,
ISNULL([Monday], 0) AS Monday,
ISNULL([Tuesday], 0) AS Tuesday,
ISNULL([Wednesday], 0) AS Wendesday,
ISNULL([Thursday], 0) AS Thursday,
ISNULL([Friday], 0) AS Friday,
ISNULL([Saturday], 0) AS Saturday
FROM ( SELECT #timesheet.Task,
#timesheet.employee,
dbo.GetWeekDayNameOfDate(#timesheet.StartDate) AS [Day],
SUM(DATEDIFF(n, #timesheet.StartDate,
#timesheet.endDate)) / 60 AS [Hours],
SUM(DATEDIFF(n, #timesheet.StartDate,
#timesheet.endDate)) % 60 AS [Minutes]
FROM #timesheet
GROUP BY #timesheet.Task,
#timesheet.employee,
dbo.GetWeekDayNameOfDate(#timesheet.StartDate)
) p PIVOT ( SUM(Hours) FOR [DAY] IN ( [Sunday], [Monday], [Tuesday], [Wednesday], [Thursday], [Friday], [Saturday] ) ) AS PivotTable
) details ON summary.Task = details.Task
AND summary.Employee = details.Employee
通过这样做我会得到以下结果：
Task employee Start Date End Date Sunday Monday Tuesday Wendesday Thursday Friday Saturday Hours Minutes
---------- ----------- ----------------------- ----------------------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- ----------- -----------
Task1 10 2011-05-10 17:00:00.000 2011-05-12 20:00:00.000 0 0 3 0 3 0 0 6 0

请注意，我几乎忽略了会议记录部分，但我希望至少这对您有所帮助。
