sql-server sql-server-2008

Sql server 如何在单个查询中获取整个月、周或日级别的数据,sql-server,sql-server-2008,Sql Server,Sql Server 2008,我有一个数据，其中我必须根据所选日期按月、周或日显示记录 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. 如果所选日期如01-01-2015至15-02-2015。现在这里有一个多月，但Feburary不在整个月内，因此january将记录在一个月内，而

我有一个数据，其中我必须根据所选日期按月、周或日显示记录

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.

如果所选日期如

01-01-2015

至

15-02-2015

。现在这里有一个多月，但

Feburary

不在整个月内，因此

januar

y将记录在一个月内，而

Feburary

的第一周记录将在一个月内提取，下周记录将在另一个月内提取

此外，他离开的那一天（第二周将有14天）将有另一个记录`

因此，在所有

4条记录中，

将被提取。在这里，我不是在浪费46天的时间，而是在浪费4天的时间。希望我给出了一个恰当的例子，如果你不能只是评论，我会用另一个例子来解释。我现在只担心如何划分月、周和日。有人能帮我吗。提前谢谢

我只担心如何将日期分为月、周或日。公式很简单，如果e有整月，则条目应显示在单个记录中。如果我们的日期介于超过一周和少于一周之间，则应显示为“周”级别

输入这里，Time_type_id是来自其他3个表的外键。这一次_type _id将有助于按天、周或月获取数据。数据根据用户传递的日期显示。Time_id是表的主键，它指向其他3个事实表的id

Fact3- This shows the monthly basis data.

    3                            12                                  September                  2015
    3                            13                                  September                  2015
    3                            14                                  September                  2015

现在用户只是传递了他想要查看数据的日期，根据传递的日期，我们必须输出数据。如果是月级别，我们必须显示Fact3表格，其中Dim_类型与其他两个表格相同。我只想知道如何分割日期

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：不要让一周总是有7天，如果一周从星期四开始，那么它就不会有7天。您可以使用两个参数，因此选择日期是动态的，例如：

Declare @FromDate DATETIME,
        @ToDate DATETIME

SELECT ...
FROM ...
WHERE DATE BETWEEN @FromDate AND @ToDate

您可以使用两个参数，因此选择日期是动态的，如：

Declare @FromDate DATETIME,
        @ToDate DATETIME

SELECT ...
FROM ...
WHERE DATE BETWEEN @FromDate AND @ToDate

在您的情况下，可以有两种解决方案：

解决方案#1

您需要一个table/tentable，其中包含所有日期的数据，包括Date、DaySrNo、WeekSrNo、MonthSrNo和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：和Fact1一样，表包含按天计算的数据，所以您需要像StartDate和EndDate这样的日期范围列同样，其他表Fact2和Fact3中有相同的两列

因此，在Join and where filter中使用此列可以获得所需的输出。
