对多个字段的 SSRS 报告进行分组

Question

我有一个我们将称为 ReportOne 的报告，在这个 ReportOne 中，我正在使用存储过程查询此报告的数据。存储过程查询 returns 两个值，即 'TravelDate' 和 'Status'。

我的报告有四个字段，'BeginDate'、'EndDate'、'Status' 和 'Days'。

我的问题是，我需要按 'Status' 天和连续天对报告进行分组。来自 TravelDate 的连续天数。

'BeginDate' 将是第一个新日期

'EndDate' 将是最后一个连续日期。

'Status' 将是状态。

'Days' 将是连续的天数。

示例，

TravelDate | Status

1/1/2001   | Leave
1/2/2001   | Leave
1/3/2001   | Leave
1/5/2001   | Leave
1/6/2001   | Travel

报告将如下所示。

BeginDate | EndDate  | Status | Days

1/1/2001  | 1/3/2001 | Leave  | 3

1/5/2001  | 1/5/2001 | Leave  | 1

1/6/2001  | 1/6/2001 | Travel | 1

Answer 1

例子

Declare @YourTable Table ([TravelDate] date,[Status] varchar(50))
Insert Into @YourTable Values 
 ('1/1/2001','Leave')
,('1/2/2001','Leave')
,('1/3/2001','Leave')
,('1/5/2001','Leave')
,('1/6/2001','Travel')


Select BeginDate=min(TravelDate)
      ,EndDate  =max(TravelDate)
      ,Status   =max(Status)
      ,Days     =datediff(DAY,min(TravelDate),max(TravelDate))+1
 From (
        Select * 
              ,Grp = DateDiff(DAY,'1900-01-01',TravelDate) - row_number() over (partition by status order by TravelDate)
         From @YourTable
      ) A
 Group By Grp
 Order By BeginDate

Returns

BeginDate   EndDate     Status  Days
2001-01-01  2001-01-03  Leave   3
2001-01-05  2001-01-05  Leave   1
2001-01-06  2001-01-06  Travel  1

编辑 -- 从存储过程中捕获 -- @YourTable 结构必须与存储过程的结构相匹配

Declare @YourTable Table ([TravelDate] date,[Status] varchar(50))
Insert Into @YourTable 
Exec youStoredProcedure

    Select BeginDate=min(TravelDate)
          ,EndDate  =max(TravelDate)
          ,Status   =max(Status)
          ,Days     =datediff(DAY,min(TravelDate),max(TravelDate))+1
     From (
            Select * 
                  ,Grp = DateDiff(DAY,'1900-01-01',TravelDate) - row_number() over (partition by status order by TravelDate)
             From @YourTable
          ) A
     Group By Grp
     Order By BeginDate
