Мне нужно преобразовать строки в столбцы на все недели для данного подтверждения, но в моем запросе оно выполняется только в течение одной недели, но существует несколько недель при одном ID. `

2     2007-08-22 00:00:00.000 Wednesday      8 

мне нужно привести в такой форме:

ConfirmationId weekstartdate weekenddate Monday Tuesday Wednesday Thursday Friday Saturday Sunday 
    1   16/07/2007  23/07/2007 NULL NULL 8   8  8  NULL  NULL 
    1   24/07/2007  30/07/2007 8  8  8   8  8  NULL  NULL 
    2   18/06/2007  24/06/2007 NULL NULL NULL  NULL  8  NULL  NULL 
    2   25/06/2007  1/07/2007 8  8  8   NULL  NULL NULL  NULL 
    2   2/07/2007  8/07/2007 8  8  NULL  8  8  NULL  NULL 

Что я пытался до сих пор:

select Confirmationid,[Monday],[Tuesday],[Wednesday],[Thursday],[Friday],[Saturday],[Sunday] 
from 
(
Select confirmationid,WorkingHours,TimeSheetDate,[DayName] from #temp1 
) d 
pivot(
min(WorkingHours) for 
[DayName] in ([Monday],[Tuesday],[Wednesday],[Thursday],[Friday],[Saturday],[Sunday]) 
)piv order by ConfirmationId 

это дает мне результат: что совершенно неправильно.

Answer 1

Вы должны использовать таблицу календаря, чтобы получить первый и последний день недели. Выберите все соответствующие поля в ците, а затем оттуда оттуда:

;WITH cte AS (SELECT ConfirmationId 
         , DayName 
         , WorkingHours 
         , b.FirstDateOfWeek 
         , b.LastDateOfWeek 
       FROM #temp1 a 
       JOIN tlkp_Calendar b 
       ON a.TimeSheetDate = b.CalendarDate 
      ) 
SELECT * 
FROM cte 
PIVOT(MIN(WorkingHours) 
     FOR [DayName] IN ([Monday],[Tuesday],[Wednesday],[Thursday],[Friday],[Saturday],[Sunday]) 
    )pvt 
ORDER BY ConfirmationId
