无法绑定多部分标识符

Question

  

可能重复：
  The multi-part identifier could not be bound

这是我不想工作的查询。

它说： 无法绑定多部分标识符“dbo.RunSequenceBatch.RunSequenceBatchName”。

你能告诉我吗？

提前致谢!!! ：）

SELECT '30 May' AS [Date],
[RunSeq].[RunSequenceBatchName] AS [Batch Job Name] ,
RunSeqCat.CategoryDescription AS [Development Name] ,
[Systems].SystemName AS [System Area] ,
CAST((SUM(DumpSM37_Env3.Duration) / 60) AS NUMERIC(10, 2)) AS [Duration (mins)] 
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'), 
[dbo].[RunSequenceType] AS RunSeqType, 
[dbo].[RunSequenceFrequency] AS RunSeqFrequency, 
RunSequenceCategory AS RunSeqCat, Category, [Systems]  
WHERE RunSeq.Status = 'Active' 
AND RunSeqFrequency.RunSequenceBatchID  = RunSeq.RunSequenceBatchID 
AND RunSeq.RunSequenceTypeID = RunSeqType.RunSequenceTypeID 
AND RunSeqCat.CategoryDescription = Category.Description 
AND Category.SystemArea = [Systems].SystemID 
AND DumpSM37_Env3.[Duration] > 0 
AND RunSeq.RunSequenceTypeID = 1 
AND RunSeqCat.RunSequenceBatchID = RunSeq.RunSequenceBatchID  
GROUP BY dbo.RunSequenceBatch.RunSequenceBatchName, DumpSM37_Env3.WorkerProcessID, 
ORDER BY [RunSeqFrequency].[Frequency] ASC, 
[RunSeqFrequency].[StartTime] ASC

Answer 1

基本上，您的表名不匹配。

在你的FROM中：

FROM [dbo].[RunSequenceBatch] AS RunSeq 

你是别名[dbo].[RunSequenceBatch]换句话说，你说明从现在开始，[dbo].[RunSequenceBatch]将被称为RunSeq

但在你的GROUP BY中，你没有使用别名来引用它。由于查询中唯一公开名称中的别名，dbo.RunSequenceBatch无法绑定。

更改

GROUP BY dbo.RunSequenceBatch.RunSequenceBatchName

到

GROUP BY RunSeq.RunSequenceBatchName

你会没事的。
