复制- dcount

Question

我正在从Outlook导入数据，并且只想导入字段中没有重复的电子邮件。

我已经尝试过DCount，它正在工作，但它仍然会复制表单中的最后一条记录。因此，如果我导入9封电子邮件，并再次点击按钮，它将不会导入任何东西，除了表单中的最后一封电子邮件。不确定为什么那个人仍然被允许通过代码...

Answer 1

考虑一下这段修改后的代码。它首先从电子邮件正文中提取RequestNumber，然后在表中搜索表中数据，如果没有找到，则创建一条新记录。

For Each OlMail In OlItems
    If OlMail.UnRead = True Or OlMail.UnRead = False Then
        reQuest = ""
        If InStr(1, OlMail.Body, "Request No.:", 1) Then
            reQuest = Mid(OlMail.Body, InStr(OlMail.Body, "Request No.:") + 13, 9)
        End If
        If reQuest <> "" Then
            If DCount("requestnumber", "import table", "[requestnumber]='" & reQuest & "'") = 0 Then
                'save data to record
                DoCmd.GoToRecord , , acNewRec
                Me.RequestNumber = request
                'extract rest of data
                abody = Split(OlMail.Body, Chr(13) & Chr(10))
                For j = 0 To UBound(abody)
                    If abody(j) <> "" Then
                        '...
                    End If
                Next
            End If
        End If
    End If
Next
