L'identificatore in più parti non poteva essere vincolato

Question

Eventuali duplicati:
The multi-part identifier could not be bound

Questa è la mia query che non vogliono lavorare.

Dice: L'identificatore di più parti "dbo.RunSequenceBatch.RunSequenceBatchName" non può essere associato.

Potresti per favore avvisare?

Grazie in anticipo !!! :)

SELECT '30 May' AS [Date], 
[RunSeq].[RunSequenceBatchName] AS [Batch Job Name] , 
RunSeqCat.CategoryDescription AS [Development Name] , 
[Systems].SystemName AS [System Area] ,

FROM [dbo].[RunSequenceBatch] AS RunSeq 
LEFT JOIN DumpSM37_Env3 ON ([RunSeq].[RunSequenceBatchName] = DumpSM37_Env3.[Job] 
AND DumpSM37_Env3.[ImportDate] BETWEEN '30 May 2012 00:00:00' AND '30 May 2012 23:59:59'),

Fondamentalmente, hai sbagliato i nomi delle tabelle.

Nella tua FROM avete:

FROM [dbo].[RunSequenceBatch] AS RunSeq 

Stai aliasing [dbo].[RunSequenceBatch] In altre parole, si sta affermando che da qui in avanti, [dbo].[RunSequenceBatch] sarà indicato come RunSeq

Ma nel tuo GROUP BY non ci si riferisce ad esso usando l'alias. Poiché l'alias nell'unico nome esposto nella query, dbo.RunSequenceBatch non può essere associato.

Change

GROUP BY dbo.RunSequenceBatch.RunSequenceBatchName 

a

GROUP BY RunSeq.RunSequenceBatchName 

E andrà tutto bene.
