Sql Access 2007错误3071-使用参数报告

我在MS Access 2007中有一个查询，它从两个不同的表中提取数据并显示在报告中。这发生在用户单击主窗体上的按钮之后，该按钮打开一个日期字段参数窗体，用户可以在其中选择两个日期。从那里，查询使用用户提供的两个日期运行，或者如果没有选择任何日期来填充日期，则这些日期是“伪造的”。我得到一个运行时错误3071，这个表达式输入错误，或者它太复杂而无法计算，我不知道为什么

我在另一个数据库中运行了一个类似的查询，它执行得非常完美，所以我不知所措

查询如下：

(SELECT 
[Group Name], 
tbGroups AS [Group Number],
Analyst, 
[Account Manager], 
NULL AS [SER Number], 
[Received Date] AS [Corporate Recevied],
DateValue(Created) AS [Sales Submitted], 
tbBAAcceptedDate AS [BA Accepted], 
NULL AS [Submitted to MDSS], 
NULL AS [Completed],
NULL AS [Cancelled],
DateDiff("d",[Received Date], IIf([Forms]![frmReportDateFilter].[tbToDate] = '01/01/2116', Date(), CDate([Forms]![frmReportDateFilter].[tbToDate]))) AS [Aging Days Count],
LocalID AS [ID Number]
FROM ChangeRequest
WHERE DateValue([Created]) BETWEEN CDate([Forms]![frmReportDateFilter].[tbFromDate]) AND CDate([Forms]![frmReportDateFilter].[tbToDate]))
UNION ALL (SELECT 
tbGroupProgramProductName AS [Group Name], 
tbGroups AS [Group Number], 
cboAnalyst AS Analyst, 
tbAccountManager AS [Account Manager], 
tbSERNumber AS [SER Number], 
tbCorpReceivedDate AS [Corporate Recevied],
tbBAReceivedDate AS [Sales Submitted],
IIf([tbBAAcceptedDate] > CDate([Forms]![frmReportDateFilter].[tbToDate]), NULL, [tbBAAcceptedDate]) AS [BA Accepted],
IIf([tbSubmittedToMDSS] > CDate([Forms]![frmReportDateFilter].[tbToDate]), NULL, [tbSubmittedToMDSS]) AS [Submitted to MDSS],
DateValue(tbCompleteDate) AS [Completed],
DateValue(tbCancelDate) AS [Cancelled],
DateDiff("d",tbCorpReceivedDate, IIf([Forms]![frmReportDateFilter].[tbToDate] = '01/01/2116', Date(), CDate([Forms]![frmReportDateFilter].[tbToDate]))) AS [Aging Days Count],
LocalID AS [ID Number]
FROM tblDD
WHERE DateValue([tbBAReceivedDate]) BETWEEN CDate([Forms]![frmReportDateFilter].[tbFromDate]) AND CDate([Forms]![frmReportDateFilter].[tbToDate]))
ORDER BY [Group Name];

非常感谢您的帮助。

请将控件指定为日期。类似这样的东西，没有CDate，也没有外括号：

PARAMETERS 
[Forms]![frmReportDateFilter].[tbFromDate] Date,
[Forms]![frmReportDateFilter].[tbToDate] Date;
SELECT 
[Group Name], 
tbGroups AS [Group Number],
Analyst, 
[Account Manager], 
NULL AS [SER Number], 
[Received Date] AS [Corporate Recevied],
DateValue(Created) AS [Sales Submitted], 
tbBAAcceptedDate AS [BA Accepted], 
NULL AS [Submitted to MDSS], 
NULL AS [Completed],
NULL AS [Cancelled],
DateDiff("d",[Received Date], IIf([Forms]![frmReportDateFilter].[tbToDate] = #01/01/2116#, Date(), [Forms]![frmReportDateFilter].[tbToDate])) AS [Aging Days Count],
LocalID AS [ID Number]
FROM ChangeRequest
WHERE DateValue([Created]) BETWEEN [Forms]![frmReportDateFilter].[tbFromDate] AND [Forms]![frmReportDateFilter].[tbToDate]
UNION ALL 
SELECT 
tbGroupProgramProductName AS [Group Name], 
tbGroups AS [Group Number], 
cboAnalyst AS Analyst, 
tbAccountManager AS [Account Manager], 
tbSERNumber AS [SER Number], 
tbCorpReceivedDate AS [Corporate Recevied],
tbBAReceivedDate AS [Sales Submitted],
IIf([tbBAAcceptedDate] > [Forms]![frmReportDateFilter].[tbToDate], NULL, [tbBAAcceptedDate]) AS [BA Accepted],
IIf([tbSubmittedToMDSS] > [Forms]![frmReportDateFilter].[tbToDate], NULL, [tbSubmittedToMDSS]) AS [Submitted to MDSS],
DateValue(tbCompleteDate) AS [Completed],
DateValue(tbCancelDate) AS [Cancelled],
DateDiff("d",tbCorpReceivedDate, IIf([Forms]![frmReportDateFilter].[tbToDate] = #01/01/2116#, Date(), [Forms]![frmReportDateFilter].[tbToDate])) AS [Aging Days Count],
LocalID AS [ID Number]
FROM tblDD
WHERE DateValue([tbBAReceivedDate]) BETWEEN [Forms]![frmReportDateFilter].[tbFromDate] AND [Forms]![frmReportDateFilter].[tbToDate]
ORDER BY [Group Name];

如果删除每个

SELECT

片段周围的括号，会发生什么情况？换句话说，

选择。。。从…起联合所有选择。。。从…

而不是从

（选择…从…）UNION ALL（选择…从…

@Hans-我也想到了这一点，当我删除它们时，我会得到相同的错误，如果内存对我来说是正确的，这会导致我之前提到的查询中的另一个错误，并且正在正确执行。我认为我在代码中遗漏了或忽略了一些东西，因为我无法摆脱这个运行时错误。在查询设计器中单独测试查询时，是否也会遇到同样的错误？如果是这样的话，您可以分别对每个

SELECT

piecle进行测试，它们是否都能正常运行？分别对这两个SELECT进行测试会让我发现，我的顶部SELECT功能正常，而底部SELECT功能正常。当我只运行查询的下半部分时，出现了相同的错误。我没有在设计器中构建SQL。很好！现在确定该查询的哪个部分导致错误。例如，如果

选择*

，是否仍会出现错误？首先，感谢您的回复！我尝试过这个，但不幸的是，它给出了相同的错误。在打开报告之前，我运行代码询问用户是否要导出到Excel，如果他们选择“否”，则会在Access中打开报告。
