【问题描述】：
我正在尝试制作一份报告，为每个月生成一个日历，用户可以在其中指定月份和年份的范围。我的矩阵在Weekday 上有一个列分组，而行分组在WeekNumber 上（请参阅下面的查询结果）。
我遇到的问题是这一天开始的地方不对如下所示：
这是因为我的查询只包含该特定月份的天数，而不是之前和之后月份的几天，通常会在日历上显示为灰色：
虽然我怀疑这个问题也可以在矩阵本身中解决，但我不确定在查询中解决它还是在矩阵中解决它会比另一个更好。
我当前的查询：
SELECT t1.[TimeSheetLineID] ,
t1.[TimeSheetID] ,
t1.[JobID] ,
t1.[TimeSheetDate] ,
t1.[TimeSheetCreatedOn] ,
t1.[TimeSheetLastModifiedOn] ,
t1.[StartTime] ,
t1.[EndTime] ,
t1.[TotalTime] ,
t1.[EmployeeName] ,
t2.DateFull ,
t2.[FullYear] ,
t2.[WeekNumber] ,
t2.[WeekDay] ,
t2.[WeekDayName] ,
t2.[MonthDay] ,
t2.[MonthName] ,
t2.[MonthNumber]
FROM dbo.DateLookup t2
LEFT JOIN [dbo].[FactTimeSheets] t1
ON t1.TimeSheetDate = t2.DateFull
AND (t1.JobID = @jobNumber)
WHERE (t2.FullYear = @year)
AND (t2.MonthNumber BETWEEN @startMonth AND @endMonth)
ORDER BY FullYear, MonthNumber, MonthDay, WeekDay
基于this article。
--更新--
我在下面的查询中使用 CTE 来获取填写此日历所需的额外日期。我在 Date 表上对其进行了测试，明天将使用最终查询更新我的答案：
DECLARE @year INT ,
@startMonth DATE ,
@endMonth DATE;
SET @year = '2016';
SET @startMonth = '2016-08-01';
SET @endMonth = '2016-08-31';
DECLARE @StartDate DATE ,
@EndDate DATE;
SET @StartDate = DATEADD(s, 0, DATEADD(mm, DATEDIFF(m, 0, @startMonth), 0));
SET @StartDate = DATEADD(DAY, -DATEPART(WEEKDAY, @StartDate) + 1, @StartDate);
--SELECT @StartDate
SET @EndDate = DATEADD(s, -1, DATEADD(mm, DATEDIFF(m, 0, @startMonth) + 1, 0));
SET @EndDate = DATEADD(DAY, 7 - DATEPART(WEEKDAY, @EndDate), @EndDate)
--SELECT @EndDate;
;
WITH Dates ( [Date] )
AS (
--Select First day in range
SELECT CONVERT(DATETIME, @StartDate) AS [Date]
UNION ALL
--Add a record for every day in the range
SELECT DATEADD(DAY, 1, [Date])
FROM Dates
WHERE Date < CONVERT(DATETIME, @EndDate)
),
Events
AS ( SELECT [FullYear] ,
[DateFull] ,
[WeekNumber] ,
[WeekDay] ,
[WeekDayName] ,
[MonthDay] ,
[MonthName] ,
[MonthNumber]
FROM [dbo].[DateLookup]
)
SELECT e.[FullYear] ,
e.[DateFull] ,
d.[Date] ,
e.[WeekNumber] ,
e.[WeekDay] ,
e.[WeekDayName] ,
e.[MonthDay] ,
e.[MonthName] ,
e.[MonthNumber]
FROM Dates d
LEFT JOIN Events e ON d.[Date] = CAST(e.DateFull AS DATE)
GROUP BY FullYear ,
MonthNumber ,
DateFull ,
d.[Date] ,
WeekNumber ,
MonthName ,
WeekDayName ,
MonthDay ,
WeekDay
ORDER BY Date;
--最终更新的查询--
我希望这对将来的人有所帮助。
SET @startDate = DATEADD(mm, DATEDIFF(m, 0, CAST(CAST(@year AS varchar) + '-' + CAST(@startMonth AS varchar) + '-01' AS DATETIME)), 0);
SET @startDate = DATEADD(DAY, -DATEPART(WEEKDAY, @startDate) + 1, @startDate);

【问题讨论】：
-
您可以在每天返回一个标志，指示它是否应该变灰。我也有这个问题。您可能需要在上个月和下个月中加入几天来平衡您的日历。
-
嗨@RossBush，您是在查询中解决了这个问题，还是在矩阵中以某种方式解决了这个问题？感谢您的评论！
-
我返回了星期一或星期日，但是您将一周的第一天配置为范围的第一天，然后计算该月的最后一天并添加最后一天的任何溢出天数星期。因此，如果最后一天是星期二，那么我返回该周的星期日作为范围的最后一天，这样我就可以添加溢出灰色效果。但是，您需要在查询中标记溢出天数，以便在矩阵中将它们涂成灰色。
-
在查询中，CalendarBlockNumber 不一定是 DayNumberInMonth。
-
您能否使用 CTE 与您的月份联合，以便用前一天的最后几天和下个月的第一天填充它？
