无法绑定多部分标识符

我在SO上看到过类似的错误，但我没有找到解决我的问题的方法。我有一个SQL查询像:

SELECT DISTINCT
        a.maxa ,
        b.mahuyen ,
        a.tenxa ,
        b.tenhuyen ,
        ISNULL(dkcd.tong, 0) AS tongdkcd
FROM    phuongxa a ,
        quanhuyen b
        LEFT OUTER JOIN ( SELECT    maxa ,
                                    COUNT(*) AS tong
                          FROM      khaosat
                          WHERE     CONVERT(DATETIME, ngaylap, 103) BETWEEN 'Sep 1 2011'
                                                              AND
                                                              'Sep 5 2011'
                          GROUP BY  maxa
                        ) AS dkcd ON dkcd.maxa = a.maxa
WHERE   a.maxa <> '99'
        AND LEFT(a.maxa, 2) = b.mahuyen
ORDER BY maxa;

当我执行这个查询时，错误结果是: 无法绑定多部分标识符“a.maxa”。为什么? P/s:如果我把查询分成2个单独的查询，它运行正常。

SELECT DISTINCT
        a.maxa ,
        b.mahuyen ,
        a.tenxa ,
        b.tenhuyen
FROM    phuongxa a ,
        quanhuyen b
WHERE   a.maxa <> '99'
        AND LEFT(a.maxa, 2) = b.mahuyen
ORDER BY maxa;

and

SELECT  maxa ,
        COUNT(*) AS tong
FROM    khaosat
WHERE   CONVERT(DATETIME, ngaylap, 103) BETWEEN 'Sep 1 2011'
                                        AND     'Sep 5 2011'
GROUP BY maxa;

对我有用的是将WHERE子句更改为SELECT子查询

来自:

    DELETE FROM CommentTag WHERE [dbo].CommentTag.NoteId = [dbo].FetchedTagTransferData.IssueId

TO:

    DELETE FROM CommentTag WHERE [dbo].CommentTag.NoteId = (SELECT NoteId FROM FetchedTagTransferData)

我在SQL SERVER中遇到了同样的错误消息，因为我有多个连接，改变连接的顺序为我解决了这个问题。

对我来说，问题是我愚蠢地调用一个DB函数没有空括号select [apo]。[GenerateNationalIdFrance]而不是select [apo].[GenerateNationalIdFrance]()…我花了几分钟才意识到这一点，但对大三学生来说值得一提:-)

相反，你可以尝试像这样连接桌子，

select 
  .... 
from 
   dkcd 
     right join 
                a
                  , b

这应该可以
