大佬教程收集整理的这篇文章主要介绍了多部分标识符无法绑定，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
基本上，您不匹配表名。
在您的FROM您有：
FROM [dbo].[RunSequenceBatch] AS RunSeq
您是别名，[dbo].[RunSequenceBatch]也就是说，从现在开始，[dbo].[RunSequenceBatch]将被称为RunSeq
但是在您中，GROUP BY您不会使用别名来引用它。因为别名在查询中唯一公开的名称中，dbo.RunSequenceBatch所以无法绑定。
改变
GROUP BY dbo.RunSequenceBatch.RunSequenceBatchname
到
GROUP BY RunSeq.RunSequenceBatchname
而且您会没事的。
这是我不希望的查询。
它说：不能绑定多部分标识符“ dbo.RunSequenceBatch.RunSequenceBatchName”。
您能否提一些建议？
提前致谢！！！:)
