Question

我知道这里已经有一些论坛了，但有人可以帮我识别重复项以及如何为列名设置别名吗？我相信底部的左连接是在报表生成器中创建此错误。

SELECT  CASE A.DTASERIES
      WHEN 2 THEN 'Financial'
      WHEN 3 THEN 'Sales'
      WHEN 4 THEN 'Purchasing'
      WHEN 5 THEN 'Inventory'
      WHEN 6 THEN 'Payroll – USA'
      WHEN 7 THEN 'Project'
      ELSE ''
    END AS DTA_Series ,
    JRNENTRY AS JournalEntry,
    D.ACTNUMST AS AccountNumber,
    C.ACTDESCR AS AccountDescription,
    A.GROUPID AS DTA_GroupID,
    CODEID AS DTA_CodeID,
    GROUPAMT ,
    CASE 
    WHEN CODEAMT > 0 THEN CODEAMT
    ELSE 0 
    END AS Debit,
    CASE 
    WHEN CODEAMT < 0 THEN CODEAMT
    ELSE 0 
    END AS Credit,
    A.TRXDATE  AS TransactionDate,
    A.DTAREF AS DTA_Reference,

    DTA_GL_Reference ,
    A.DOCNUMBR AS OriginalDocumentNumber ,
    A.RMDTYPAL ,
    CASE PSTGSTUS
      WHEN 1 THEN 'Unposted'
      WHEN 2 THEN 'Posted'
      ELSE ''
    END AS DTA_PostingStatus ,
    B.DOCNUMBR ,
    B.RMDTYPAL ,
    POSTDESC AS PostingDescription,
    DTAQNTY 
    FROM    dbo.DTA10100 AS A
    LEFT OUTER JOIN dbo.DTA10200 AS B ON A.ACTINDX = B.ACTINDX
                                         AND A.DOCNUMBR = B.DOCNUMBR
                                         AND A.DTAREF = B.DTAREF
                                         AND A.DTASERIES = B.DTASERIES
                                         AND A.GROUPID = B.GROUPID
                                         AND A.SEQNUMBR = B.SEQNUMBR
    LEFT OUTER JOIN dbo.GL00100 AS C ON A.ACTINDX = C.ACTINDX
    LEFT OUTER JOIN dbo.GL00105 AS D ON C.ACTINDX = D.ACTINDX

Answer 1

SSRS仅在确定数据集的字段时查看列名称，如果SELECT两个具有相同名称的列来自一个或多个表，则会抛出此错误。

在这种情况下，您的A.RMDTYPAL子句中有B.RMDTYPAL和SELECT，SSRS视为两个RMDTYPAL列。别名中的一个或两个都会消失。

有关详情，请参阅this similar question。

编辑:(为清楚起见，我只列出了两列）

SELECT  
    A.RMDTYPAL AS A_RMDTYPAL,
    B.RMDTYPAL AS B_RMDTYPAL
FROM dbo.DTA10100 AS A
    LEFT OUTER JOIN dbo.DTA10200 AS B ON A.ACTINDX = B.ACTINDX
                                     AND A.DOCNUMBR = B.DOCNUMBR
                                     AND A.DTAREF = B.DTAREF
                                     AND A.DTASERIES = B.DTASERIES
                                     AND A.GROUPID = B.GROUPID
                                     AND A.SEQNUMBR = B.SEQNUMBR
    LEFT OUTER JOIN dbo.GL00100 AS C ON A.ACTINDX = C.ACTINDX
    LEFT OUTER JOIN dbo.GL00105 AS D ON C.ACTINDX = D.ACTINDX

Answer 2

以防它帮助其他人：

我在SSRS 2008，SQL Server 2008 R2中遇到了同样的错误。我的存储过程正在执行SELECT * FROM #Results以返回结果集。没有重复的列名称/别名＆＃39; s。但是，当我将其切换为仅选择所有列而不是*时，它解决了问题。
