無効な列名です。ERROR

Question

以下の簡単なクエリがあります。しかし、なぜ私はフィールド名とエラー値のwhere句で無効な列名エラーを取得しているのかわかりません。

select * From (
    select [SubscriberDataId] 
    ,Case When ISNUMERIC([SubscriberCode]) = 0 Then cast([SubscriberCode]as varchar(9)) Else '~' end as [SubscriberCode] 
    ,Case When ISDATE([Dob]) = 0 Then Cast([Dob] as Varchar(9)) Else '~' end as [Dob] 
    ,Case When ISNUMERIC([FacetsGroup]) = 0 Then cast([FacetsGroup]as varchar(9)) Else '~' end as [FacetsGroup] 
    from Facets.SubscriberData) [sd] 
    Unpivot 
    (ErrorValue for FieldName in ([SubscriberCode], 
    [Dob],[FacetsGroup])) as x 
    where x.ErrorValue <> '~' and 
      NOT EXISTS (SELECT * 
    FROM Elig.dbo.ErrorTable 
       WHERE TableName = facets.SubscriberData 
    AND FieldName IN([x].[SubscriberCode],[x].[Dob],[x].[FacetsGroup]) 
       AND ErrorValue IN([SubscriberCode],[Dob],[FacetsGroup]))

、あなたがあなたの前の質問に十分な書式設定の例を持っている

select * From 
    (select [SubscriberDataId], 
     Case When ISNUMERIC([SubscriberCode]) = 0 
      Then cast([SubscriberCode]as varchar(9)) 
      Else '~' end as [SubscriberCode], 
     Case When ISDATE([Dob]) = 0 
      Then Cast([Dob] as Varchar(9)) 
      Else '~' end as [Dob], 
     Case When ISNUMERIC([FacetsGroup]) = 0 
      Then cast([FacetsGroup]as varchar(9)) 
      Else '~' end as [FacetsGroup] 
from Facets.SubscriberData) [sd] 
Unpivot (ErrorValue for FieldName in ([SubscriberCode], [Dob],[FacetsGroup])) as x where x.ErrorValue <> '~' 
and NOT EXISTS (SELECT * FROM Elig.dbo.ErrorTable     
       WHERE TableName = facets.SubscriberData  
       AND FieldName IN('[x].[SubscriberCode]','[x].[Dob]','[x].[FacetsGroup]') 
       AND ErrorValue IN('[SubscriberCode]','[Dob]','[FacetsGroup]'))
