forms - 表单搜索以查找子表单中具有值的所有记录（无论字段值如何）

Question

搜索论坛后，我没有找到任何像我一样的问题/答案。

我有一个包含四个不同搜索字段的主表单——姓氏、城市、电话号码和 ID。我想搜索这些字段中的任何一个（或这些字段的组合）以查找子表单中具有匹配值的所有记录 - 无论该值在哪个字段中（即子表单中有多个地址字段，所以城市可能出现在其中任何一个中）。

此外，如果输入姓氏和城市，我只想返回包含这两个值的子表单中的记录。

先感谢您！

我认为不使用 VBA 就无法做到这一点。您需要将代码添加到主窗体上每个AfterUpdate搜索字段的控件的事件中，以便随后更新子窗体的过滤器。不过，我不确定允许使用多复杂的过滤器，这可能是个问题，因为它将成为过滤器的怪物。

这是一个未经测试的示例，它使用占位符来表示子表单中不同字段的潜在数量（正如您所指出的那样，它们可能有多个），并假设您的电话号码和 ID 是数字，并且您的搜索控件已进行数据验证以确保这件事：

Private Sub last_name_AfterUpdate()
    Call FilterSubForm()
End Sub

Private Sub city_AfterUpdate()
    Call FilterSubForm()
End Sub

Private Sub phone_number_AfterUpdate()
    Call FilterSubForm()
End Sub

Private Sub ID_AfterUpdate()
    Call FilterSubForm()
End Sub

Private Sub FilterSubForm()
    Dim sLastName As String
    Dim sCity As String
    Dim sPhone As String
    Dim sID As String
    Dim sFilter As String

    sLastName = Trim(Me.[last name])
    sCity = Trim(Me.city)
    sPhone = Trim(Me.[phone number])
    sID = Trim(Me.ID)

    If sLastName != "" And sCity != "" Then     
            sFilter = "(([last_name_1] = '" & sLastName & "' " _
                            & "OR [last_name_2] = '" & sLastName & "' " _
                            & "OR [last_name_etc] = '" & sLastName & "') " _
                            & "AND " _
                            & "([city_1] = '" & sCity & "' " _
                            & "OR [city_2] = '" & sCity & "' " _
                            & "OR [city_etc] = '" & sCity & "'))"
            If sPhone != "" Then
                    sFilter = sFilter _
