Борьба с отказом от сотрудничества

Question

У меня есть таблица, которая имеет большое количество столбцов и выглядит так:

 SELECT TOP 1000 [EXTVOLUMELABELID]
  ,[FCVOLUMEDRVRID]
  ,[BUSINESSDT]
  ,[H00I1]

  ,[H02I4]
  ,[H03I1]

  ,[OFFSETFROMMIDNIGHTNUM]
  ,[UPDATEDTM]
  FROM [POSVOLUMEHIST]

Я бы хотел, чтобы в выходном формате были только следующие столбцы:

EXTVOLUMEID, BUSINESSDT, TIME (с псевдонимом из столбцов, которые выглядят так: H00I2 и т. Д.), Значение (значения из столбцов времени)

Пока у меня есть это:

USE tkcsdb

SELECT  ORGREPORT.ORGNM
  ,CONVERT (DATE, POS.BUSINESSDT) As 'Date'
  ,start_time
  ,footfall_count


  FROM POSVOLUMEHIST POS

  JOIN FCCATEGORY CAT
  ON POS.EXTVOLUMELABELID = CAT.EXTVOLUMELABELID

  JOIN ORG ORG
  ON CAT.ORGIDSID = ORG.ORGIDSID

  JOIN ORG ORGREPORT
  ON ORG.REPORTTOORGID = ORGREPORT.ORGIDSID

UNPIVOT (footfall_count for start_time in

(      POS.H08I1
  ,POS.H08I2
  ,POS.H08I3
  ,POS.H08I4
  ,POS.H09I1
  ,POS.H09I2
  ,POS.H09I3
  ,POS.H09I4
  ,POS.H10I1
  ,POS.H10I2
  ,POS.H10I3
  ,POS.H10I4

  ,POS.H12I2
  ,POS.H12I3

  ,POS.H13I4
  ,POS.H14I1
  ,POS.H14I2
  ,POS.H14I3
  ,POS.H14I4
  ,POS.H15I1
  ,POS.H15I2
  ,POS.H15I3
  ,POS.H15I4
  ,POS.H16I1
  ,POS.H16I2
  ,POS.H16I3
  ,POS.H16I4
  ,POS.H17I1
  ,POS.H17I2
  ,POS.H17I3
  ,POS.H17I4
  ,POS.H18I1
  ,POS.H18I2
  ,POS.H18I3
  ,POS.H18I4
  ,POS.H19I1
  ,POS.H19I2
  ,POS.H19I3
  ,POS.H19I4
  ,POS.H20I1
  ,POS.H20I2
  ,POS.H20I3
  ,POS.H20I4
  ,POS.H21I1
  ,POS.H21I2
  ,POS.H21I3
  ,POS.H21I4
  ,POS.H22I1
))


  WHERE

  CAST (POS.BUSINESSDT as Date) >= 'Mar 26, 2018'

  AND

  CAST (POS.BUSINESSDT as Date) <= 'Apr 01, 2018'

    ORDER BY ORGREPORT.ORGNM, POS.BUSINESSDT;

Я получаю неверный синтаксис рядом с ключевым словом "ГДЕ".

Я не могу понять, почему это не работает. Я не могу удалить предложение where для проверки, так как он вернет миллионы результатов.

Есть идеи, что я делаю не так?

Answer 1

Синтаксис для PIVOT:

SELECT <non-pivoted column>,  
    [first pivoted column] AS <column name>,  
    [second pivoted column] AS <column name>,  
    ...  
    [last pivoted column] AS <column name>  
FROM  
    (<SELECT query that produces the data>)   
    AS <alias for the source query>  
PIVOT  
(  
    <aggregation function>(<column being aggregated>)  
FOR   
[<column that contains the values that will become column headers>]   
    IN ( [first pivoted column], [second pivoted column],  
    ... [last pivoted column])  
) AS <alias for the pivot table>  
<optional ORDER BY clause>; 

Как видите, у вас не может быть предложения WHERE, следующего или следующего за предложением PIVOT / UNPIVOT.

Чтобы преодолеть это, переместите логику WHERE во вложенный запрос:

USE tkcsdb

SELECT  ORGREPORT.ORGNM
  ,CONVERT (DATE, POS.BUSINESSDT) As 'Date'
  ,start_time
  ,footfall_count


  FROM 
  (
    SELECT * 
    FROM POSVOLUMEHIST 
    WHERE CAST (BUSINESSDT as Date) >= 'Mar 26, 2018'
      AND CAST (BUSINESSDT as Date) <= 'Apr 01, 2018'
  ) POS

  JOIN FCCATEGORY CAT
  ON POS.EXTVOLUMELABELID = CAT.EXTVOLUMELABELID

  JOIN ORG ORG
  ON CAT.ORGIDSID = ORG.ORGIDSID

  JOIN ORG ORGREPORT
  ON ORG.REPORTTOORGID = ORGREPORT.ORGIDSID

UNPIVOT (footfall_count for start_time in
