将 CSV 文件从 SharePoint Online 文档库导入 Access 数据库

Question

我在 SharePoint Online 文档库中上传了一个 CSV 文件，该文件每天都会更新。我使用这个 CSV 文件来创建一些带有 Access 数据库的报告。我想要实现的是自动将 CSV 文件导入 Access，而无需在本地下载和保存 CSV 文件。我使用的代码如下：

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，它要么要求我登录，然后说我无权访问该文件，要么没有执行说它无法加载 HTML 页面...

不要被链接的标题所迷惑。

您不能直接通过 HTTP 导入/链接文件。代码为你下载文件，准备链接：

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

支持代码模块：

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

    DownloadFile = lngRetVal
