如何为开始日期和结束日期之间的每个工作日创建多行

Question

我想为我的开始日期和结束日期之间的每个工作日创建一行。 这样就可以将生产量分配到实际周，而不仅仅是开始周。

我现在所拥有的：

SELECT DISTINCT
      PH.ProdHeaderOrdNr,
      PH.ProdstatusCode,
      PH.partcode,
      PH.description,
      PBOM.subpartcode,
      PBOM.description as N'Description subpart',
      PBOO.qty,
      PBOO.producedqty,
      PBOO.machcycletime,
      PBOO.qty-PBOO.producedqty as N'to produce',
      case when(PBOO.qty-PBOO.producedqty)*(1+(convert(decimal(4,2),PBOM.waste)/100))<=0 
           then 0 
           else (PBOO.qty-PBOO.producedqty)*(1+(convert(decimal(4,2),PBOM.waste)/100)) 
           end as N'amount subpart needed',
      (DATEDIFF(dd, PBOO.startdate, PBOO.enddate) + 1)
              -(DATEDIFF(wk, PBOO.startdate, PBOO.enddate) * 2)
              -(CASE WHEN DATENAME(dw, PBOO.startdate) = 'Sunday' THEN 1 ELSE 0 END)
              -(CASE WHEN DATENAME(dw, PBOO.enddate) = 'Saturday' THEN 1 ELSE 0 END)
              As NoOfWeekDays,
      case when PBOO.machcycletime *((PBOO.qty-PBOO.producedqty)/PBOO.qty)/3600<=0 
           then 0 
           else  Round(PBOO.machcycletime *((PBOO.qty-PBOO.producedqty)/PBOO.qty)/3600,2) 
           end as N'hours remaining',
      PBOO.startdate,
      PBOO.enddate,
      datepart(year,PBOO.startdate) as N'Year',
      datepart(isoww,PBOO.startdate) as N'Week'

FROM
         dbo.T_ProductionHeader  AS PH,
         dbo.T_ProdBillofMat as PBOM,
         dbo.T_Part as P,
         dbo.T_ProdBillOfOper as PBOO,
         dbo.T_MachGrp as M

Where
    PH.ProdHeaderDossierCode = PBOM.ProdHeaderDossierCode    AND
    PH.ProdHeaderDossierCode = PBOO.ProdHeaderDossierCode AND
    PBOO.MachGrpCode = M.MachGrpCode AND
    M.DeptCode = '0720' and
    PH.ProdStatusCode BETWEEN 30 and 40 AND
    PBOM.LineNr = '10' and
    left(PH.partcode,1) in ('P', 'H')and
    PBOO.finishedInd = 0

导致：

我想得到下一个结果：

n 行数，其中 N 等于从开始到结束日期的工作日数，以下列的值分布在这些工作日内

• “生产”
• “所需的金额子部分”
• “剩余小时数”

添加的列

• “运行日期”（工作日的日期）
• “运行年份”（运行日期的年份）
• “运行周”（运行日期的等周）

我删除了“NoOfWeekDays”列

我试图创建一个 CTE，但无法让它工作。

Answer 1

首先创建日历表。

以您想要的任何方式填充。

create table CalendarDate(Dates DateTime primary key)
insert into CalendarDate WITH (TABLOCK)  (Dates)
select top (1000000) 
DATEADD(day, ROW_NUMBER()over(order by (select null))-1,'1970-01-01') DT
from sys.objects

假设您的主要查询在 CTE 内（此脚本未经测试）

With CTE As
(
 Select ,
DATEDIFF(dd, PBOO.startdate, PBOO.enddate) + 1 as Diff
From 
)

Select c.*
,ca.RunningDates 
'to produce'/Datediff
'amount subpart needed'/Datediff
from
CTE C
cross apply(select Dates as RunningDates from CalendarDate CD where cd.dates>=c.Startdate and cd.dates<=c.enddate)ca

这是答案的一个重要部分。如果这是正确的，那么您可以继续进行。

我希望我的改变很清楚。

像“生产”这样的别名是错误的，它应该是一个词 ToProduce。

编辑 1,

create table #temp (startdt datetime,enddate datetime)
insert into #temp values('2010-01-01','2010-01-05')
,('2011-02-01','2011-02-06')

select t.*,ca.RunningDate from #temp t
cross apply(select cd.Dates as RunningDate 
from CalendarDate cd 
where cd.Dates>=t.startdt and cd.Dates<=t.enddate)ca

select t.*,cd.Dates as RunningDate from #temp t
inner join  CalendarDate cd 
on cd.Dates>=t.startdt and cd.Dates<=t.enddate

drop table #temp

检查你自己，它按预期工作正常。

然而，交叉应用导致只有第一行以相同的运行日期值无休止地显示

不是因为CROSS APPLY。原因一定是别的东西。调试并找到它。 you.Once 评论 CROSS APPLY 部分并检查结果或验证值 Calendar Table。

dbo.T_ProductionHeader AS PH，dbo.T_ProdBillofMat 作为 PBOM，

不好的做法。 明确提及 JOIN 语法。 意外加入笛卡尔积的风险较小。 逗号连接是上个世纪的事情。它也使其他人更容易理解。

dbo.T_ProductionHeader  AS PH inner join
 dbo.T_ProdBillofMat as PBOM on PH.ProdHeaderDossierCode = PBOM.ProdHeaderDossierCode    AND
    PH.ProdHeaderDossierCode = PBOO.ProdHeaderDossierCode AND

将额外的过滤器放在 where 子句上，例如PH.ProdStatusCode BETWEEN 30 and 40 。
