SQL - Dynamic Pivot - Как это исправить?

/ 22 марта 2019

Итак, я нашел динамический сводный код и пытался применить его для своих нужд, но я получаю сообщение об ошибке:

Сообщение 8156, Уровень 16, Состояние 1, Строка 52 Столбец ':Id 'был указан несколько раз для' PVTTable '.Сообщение 4104, уровень 16, состояние 1, строка 45 Не удалось связать идентификатор из нескольких частей "T2.PartNumber".

Вот мой код: 

DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
DECLARE @ColumnName AS NVARCHAR(MAX)

--Get distinct values of the PIVOT Column 
SELECT @ColumnName= ISNULL(@ColumnName + ',','') 
       + QUOTENAME([Designation <en>])
FROM (SELECT DISTINCT [Designation <en>] FROM [HellaPim].[dbo].[MasterData.Countries]) AS Country

--Prepare the PIVOT query using the dynamic 
SET @DynamicPivotQuery = 
  N'SELECT T2.[PartNumber] as ArtNr, ' + @ColumnName + '
    FROM [HellaPim].[dbo].[Article.ArticleCarPark] T1 WITH (NOLOCK)
            LEFT OUTER JOIN [HellaPim].[dbo].[Article.Articles] T2 WITH (NOLOCK)
                ON T2.[ArticleID]=T1.[Article:Link]
            LEFT OUTER JOIN [HellaPim].[dbo].[MasterData.Countries] T3 WITH (NOLOCK)
                ON T3.[CountryCode]=T1.[Country:Link]
    PIVOT(SUM(T1.[PassengerCars]) 
          FOR T3.[Designation <en>] IN (' + @ColumnName + ')) AS PVTTable'
--Execute the Dynamic Pivot Query
EXEC sp_executesql @DynamicPivotQuery

сводный код работает нормально на статической таблице, проблема возникла, когда я пытался связать таблицу с другими.Это правда [: Id] присутствует во всех моих 3 таблицах, но я ими не пользуюсь.

Есть какие-нибудь намеки на то, что мне не хватает?

Thx

Я только что внес некоторые изменения в ваш динамический SQL-запрос, это может помочь Вам 

   DECLARE @DynamicPivotQuery AS NVARCHAR(MAX)
   DECLARE @ColumnName AS NVARCHAR(MAX)


    SET @DynamicPivotQuery = 
              N'SELECT ArtNr, ' + @ColumnName + ' 
                FROM
                (
                SELECT T2.[PartNumber] as ArtNr,
                       T3.[Designation <en>]
                FROM [HellaPim].[dbo].[Article.ArticleCarPark] T1 WITH (NOLOCK)
                    LEFT OUTER JOIN [HellaPim].[dbo].[Article.Articles] T2 WITH (NOLOCK)
                        ON T2.[ArticleID]=T1.[Article:Link]
                    LEFT OUTER JOIN [HellaPim].[dbo].[MasterData.Countries] T3 WITH (NOLOCK)
                        ON T3.[CountryCode]=T1.[Country:Link]
                ) AS Src
                PIVOT
                (
                SUM(Src.[PassengerCars]) FOR Src.[Designation <en>] IN (' + @ColumnName + ')
                ) AS PVTTable'
EXEC sp_executesql @DynamicPivotQuery

Извините за поздний ответ, вот печать моего оригинального синтаксиса:

The column ':Id' was specified multiple times for 'PVTTable'.

Также вот примерные данные каждой вкладки в CSV: выборка данных из 3 таблиц

Спасибо!
