Sql 在查询更改和重新查询后，导航子窗体中的子报表不会重新加载

我在导航子窗体中有一个子报表，它使用多选列表框定义要在同一窗体的子报表中查询和显示的条件。我正在使用此查询

表单！[主要]！[导航子窗体]。窗体！[客户报告]。报告。重新查询

在整个项目中以这种方式更改报告，效果非常好，但是当我在事件代码中使用它时，它不会崩溃，也不会更新报告视图。如果我单独打开报告，一切都很好，工作正常

Set qdf = db.QueryDefs("ETIC by Customer")
For Each i In [Forms]![Main]![NavigationSubform].[Form]! [Combo11].ItemsSelected
     strCriteria = strCriteria & "," & Chr(34) & [Forms]![Main]![NavigationSubform].[Form]![Combo11].ItemData(i) & Chr(34)
   Next i strCriteria = Mid(strCriteria, 2)
If Len(strCriteria) = 0 Then

Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery
qdf.SQL = strSQL
Set db = Nothing
Set qdf = Nothing

我认为您需要切换这两条线路：

Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery
qdf.SQL = strSQL

到

此外，来自MSDN：“如果不删除TempVar对象，它将保留在内存中，直到您关闭数据库。最好在使用完TempVar对象变量后删除它们。”链接：

'update the query (sql) first.
qdf.SQL = strSQL
'then requery the form.
Forms![Main]![NavigationSubform].Form![ETIC By Customer Report].Report.Requery
