L'identifiant plusieurs parties columnName ne pouvait pas être lié

Question

Je sais que cette question a été affichée à plusieurs reprises, mais après 1 heure sur Google je ne peux toujours pas obtenir ce travail

SELECT 
    ROW_NUMBER() OVER(ORDER BY x.Year DESC, x.Month) AS ID, 
    x.*, 
    Finance.fGetRates(x.XTimeStamp) 
FROM 
    ( SELECT Client, 
       Month(TimeStamp) As Month, 
       Year(TimeStamp) As Year, 
       Day(TimeStamp) As Day, 
       (dateadd(yy,(Year(TimeStamp)-1900),0) 
       + dateadd(mm,Month(TimeStamp)-1,0) 
       + Day(TimeStamp)-1) AS XTimeStamp, 
       Sum(KwTop) As KwTop, 
       Sum(KwHeap) as KwHeap, 
       Sum(KwLow) As KwLow 
     FROM Ori.vEnergyUnion 
     GROUP BY Year(TimeStamp), Month(TimeStamp),Day(TimeStamp), Client 
    ) x 

LEFT OUTER JOIN Finance.fGetRates(x.XTimeStamp) Fr 
    ON Fr.ValidFrom = x.XTimeStamp 
ORDER BY Fr 

Msg 4104, Niveau 16, État 1, ligne 19 L'identificateur en plusieurs parties "x.XTimeStamp" n'a pas pu être lié.

Toute aide serait appréciée, Merci.

Vous ne pouvez pas passer les paramètres aux fonctions sur JOIN.

Utilisation APPLY:

SELECT ROW_NUMBER() OVER(ORDER BY x.Year DESC, x.Month) AS ID, 
     x.*, 
     fr.* 
FROM (
     SELECT Client, 
       Month(TimeStamp) As Month, 
       Year(TimeStamp) As Year, 
       Day(TimeStamp) As Day, 
       (dateadd(yy,(Year(TimeStamp)-1900),0) 
       + dateadd(mm,Month(TimeStamp)-1,0) 
       + Day(TimeStamp)-1) AS XTimeStamp, 
       Sum(KwTop) As KwTop, 
       Sum(KwHeap) as KwHeap, 
       Sum(KwLow) As KwLow 
     FROM  Ori.vEnergyUnion 
     GROUP BY 
       Year(TimeStamp), Month(TimeStamp),Day(TimeStamp), Client 
     ) x 
OUTER APPLY 
     (
     SELECT * 
     FROM Finance.fGetRates(x.XTimeStamp) Fr 
     WHERE fr.ValidFrom = x.XTimeStamp 
     ) fr
