將 CSV 文件從 SharePoint Online 文檔庫導入 Access 數據庫

Question

我在 SharePoint Online 文檔庫中上傳了一個 CSV 文件，該文件每天更新​​。 我使用這個 CSV 文件來創建一些帶有 Access 數據庫的報告。 我想要實現的是將 CSV 文件自動導入 Access，而無需在本地下載和保存 CSV 文件。 我使用的代碼如下：

Sub ImportCSV()

   DoCmd.TransferText TransferType:=acLinkDelim, TableName:="Daily_Report_Table", FileName:="https://mycompany.sharepoint.com/teams/Daily%20Reporting.csv", HasFieldNames:=True

End Sub

但是，它要么要求我登錄，然后說我無權訪問該文件，要么不執行說它無法加載 HTML 頁面...

不要被鏈接的標題所迷惑。

您不能直接通過 HTTP 導入/鏈接文件。 代碼為您下載文件，准備鏈接：

Sub ImportCSV()

    Dim Result As Long
    Dim Url As String
    Dim Filename As String

    Url = "https://mycompany.sharepoint.com/teams/Daily%20Reporting.csv"
    Filename = "C:\Imports\DailyReporting.csv"

    Result = DownloadFile(Url, Filename)
    If Result = 0 Then
        DoCmd.TransferText TransferType:=acLinkDelim, TableName:="Daily_Report_Table", FileName:=Filename, HasFieldNames:=True 
    End If

End Sub

配套代碼模塊：

Option Compare Database
Option Explicit

Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" ( _
    ByVal pCaller As Long, _
    ByVal szURL As String, _
    ByVal szFileName As String, _
    ByVal dwReserved As Long, _
    ByVal lpfnCB As Long) _
    As Long

Public Function DownloadFile( _
    ByVal strURL As String, _
    ByVal strLocalFilename As String) _
    As Long

    Dim lngRetVal As Long

    lngRetVal = URLDownloadToFile(0, strURL & vbNullChar, strLocalFilename & vbNullChar, 0, 0)

    DownloadFile = lngRetVal

End Function
