SQL查询忽略它引用的控件

我有一个访问表单，其中包含一个从以下查询获取数据的列表框：

SELECT tblFUNDS.MorningsStar_Fund_Name, tblFUNDS.ISIN, tblFUNDS.RDR AS [Retro Frei], 
tblMorningstar_Data.[DEU Tax Transparence], tblMorningstar_Data.[Distribution Status], 
tblISIN_Country_Table.Country

FROM 
(tblFUNDS INNER JOIN tblISIN_Country_Table ON tblFUNDS.ISIN = tblISIN_Country_Table.ISIN) 
INNER JOIN tblMorningstar_Data ON 
(tblFUNDS.Fund_Selection = tblMorningstar_Data.Fund_Selection) 
AND (tblFUNDS.ISIN = tblMorningstar_Data.ISIN)

GROUP BY tblFUNDS.MorningsStar_Fund_Name, tblFUNDS.ISIN, tblFUNDS.RDR, 
tblMorningstar_Data.[DEU Tax Transparence], tblMorningstar_Data.[Distribution Status], 
tblISIN_Country_Table.Country, tblFUNDS.Fund_Selection

HAVING (((tblFUNDS.RDR) Like Nz([Forms]![frmMain]![ddnRDR],'*')) AND
((tblMorningstar_Data.[DEU Tax Transparence]) Like Nz([Forms]![frmMain]![ddnTax],'*')) AND
((tblMorningstar_Data.[Distribution Status]) Like Nz([Forms]![frmMain]![ddnDistribution],'*')) 
AND ((tblISIN_Country_Table.Country) Like Nz([Forms]![frmMain]![ddnCountry].[Text],'*')) 
AND ((tblFUNDS.Fund_Selection)=0));

我已经设置了查询引用的各种控件，以便在单击各种下拉字段的

\u AfterUpdate

事件上运行上述相同的SQL语句。它们都会执行，我可以通过a）列表框更新和b）设置断点来判断

问题在于： 例如，当我更改country下拉字段的值时，它会按国家过滤。然后，如果我为Tax设置下拉字段，它将为Tax进行文件归档，但忽略在country下拉控件中设置的值（以及其他下拉控件中的所有值）

我的问题： 为什么会发生这种情况？我如何让它一次根据所有下拉字段的值进行筛选？

与“注释”类似，请尝试：

SELECT tblFUNDS.MorningsStar_Fund_Name, tblFUNDS.ISIN, tblFUNDS.RDR AS [Retro Frei], tblMorningstar_Data.[DEU Tax Transparence], tblMorningstar_Data.[Distribution Status], tblISIN_Country_Table.Country

FROM (tblFUNDS INNER JOIN tblISIN_Country_Table ON tblFUNDS.ISIN = tblISIN_Country_Table.ISIN) INNER JOIN tblMorningstar_Data ON (tblFUNDS.Fund_Selection = tblMorningstar_Data.Fund_Selection) AND (tblFUNDS.ISIN = tblMorningstar_Data.ISIN)

WHERE (((tblFUNDS.RDR) Like Nz([Forms]![frmMain]![ddnRDR],'*')) AND ((tblMorningstar_Data.[DEU Tax Transparence]) Like Nz([Forms]![frmMain]![ddnTax],'*')) AND ((tblMorningstar_Data.[Distribution Status]) Like Nz([Forms]![frmMain]![ddnDistribution],'*')) AND ((tblISIN_Country_Table.Country) Like Nz([Forms]![frmMain]![ddnCountry].[Text],'*')) AND ((tblFUNDS.Fund_Selection)=0))

GROUP BY tblFUNDS.MorningsStar_Fund_Name, tblFUNDS.ISIN, tblFUNDS.RDR, tblMorningstar_Data.[DEU Tax Transparence], tblMorningstar_Data.[Distribution Status], tblISIN_Country_Table.Country, tblFUNDS.Fund_Selection;

很抱歉，很明显，但是在您更新国家/地区组合框后，其他文本框的值是否仍然存在？尝试将它们传递到消息框中，或将它们存储在变量中，您可以观察这些变量，以查看到底传递给查询的参数是什么？尝试将它们传递到消息框中，或将它们存储在变量中，您可以观察这些变量，以查看到底传递给查询的参数是什么？尝试将它们传递到消息框中，或将它们存储在变量中，您可以观察这些变量，以查看到底传递给查询的参数是什么？尝试将它们传递到消息框中，或将它们存储在变量中，您可以观察这些变量，以查看到底传递给查询的参数是什么

问题是ddnCountry表单的绑定列引用了错误的列。它与我使用ListBox查询的列不匹配

事件的查询吗？因为我没有看到你提到的“Tax”上的过滤器？@Wouter Yes这是所有“AfterUpdate”事件运行的查询。我拿出纳税申报单来做实验。。。很抱歉。我会把它放回去更新。就我所知，SQL基本上没有错。但是你不应该使用过滤器（也许这就是问题所在）。在WHERE语句中使用它。have是用于聚合函数的，请看这里，也许还有其他方法，它涉及一些vba编码。可以将列表框的记录源设置为在VBA中创建的查询。我以前在子表单中成功地完成了这项工作。您必须创建一个模块来检查每个文本框是否为空。如果没有，则可以在变量中创建筛选器，然后可以将所有变量组合在一起。问题是ddnCountry表单的绑定列引用了错误的列。它与我使用ListBox查询的列不匹配！谢谢你的帮助！这是运行所有
