我有一个数据，我必须根据所选日期按月或按周或按日显示记录。
If the date selected is for a whole month for like january its 01-01-2015 to 31-01-2015
then it should fetch for the record for the whole month.
如果选择的日期类似于01-01-2015到15-02-2015。现在这里有一个多月，但Feburary不是整月，所以januar y将记录在一个，下一个第一周记录Feburary将在一个中提取下周将有另一个记录。
他离开的那天（因为第二周将有14天）将会有另一个记录。
因此，将提取所有4 record。在这里，我只是制作了4条记录而不是整个46天的记录。希望我给出一个恰当的例子，如果你不能发表评论我将用另一个例子来解释。我现在只是担心如何分割月，周和日。任何人都可以帮助我。提前致谢
我只担心如何按月或一天分割日期。如果e有整月，则该公式很简单，该条目应显示在单个记录中。如果我们在超过一周之间的日期，它应该周显示，少于一周它应该是在日级别
输入 这里Time_type_id是来自其他3个表的外键。这个time_type_id将有助于每天，每周或每月获取数据。根据用户传递的日期显示数据。 Time_id是表的主键，它指向其他3个事实表的id。

现在，用户刚刚通过了他希望查看数据的日期，并且根据已通过的日期，我们必须查看输出。 如果是月级，我们必须显示Fact3表，其中Dim_type与其他两个表相同。我只想要如何分割日期
输出 -
第二个例子 -
Sr no id data (from the date range)
1 1 data from whole January
2 2 data from first week of Feburary
3 3 data from second week of Feburary
4 4 data from 15 Febuaray
注意：如果一周从Thrusday开始，那么一周总是有7天可能没有7天
答案 0 :(得分：0)
您可以使用两个参数，因此可以选择日期，例如：
Declare @FromDate DATETIME,
@ToDate DATETIME
SELECT ...
FROM ...
WHERE DATE BETWEEN @FromDate AND @ToDate
答案 1 :(得分：0)
您的案例中可以使用两种解决方案：
解决方案＃1
您需要一个表/ temptable，其中包含所有日期的数据，其中包含Date，DaySrNo，WeekSrNo，MonthSrNo和Further YearSrNo等列。在Join中使用此表并在三个表（也在JOIN中）中获取数据
解决方案＃2 现有表结构中的日期范围需要额外的列： 像In Fact1表一样包含日期数据，所以你需要像StartDate和EndDate这样的日期范围列 相同的方式在其他表Fact2和Fact3
中相同的两列因此，在Join和where过滤器中使用此列可以获得所需的输出。
