Question

我想对所有包含在单个Excel工作簿中的表运行SQL查询。我的VBA代码使用ADODB运行这些SQL查询。

将工作簿保存在OneDrive中时，打开连接失败，但是将工作簿保存到本地驱动器时，打开连接起作用。

在保存在OneDrive中的同时，如何在单个excel工作簿中的表上运行SQL？

当书籍保存在本地但不在OneDrive上时，该代码才有效。唯一的变化是文件路径在每种情况下看起来都大不相同：

OneDrivePathExample = "https://d.docs.live.net/....xlsb"

LocalPathExample = "C:\My Documents\....xlsb"

我已经在连接字符串中围绕文件路径进行了一些尝试，但是，毫无疑问，它们不起作用：

原始

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=https://d.docs.live.net/.../Documents/Financial Tracker.xlsb;Extended Properties="Excel 12.0;HDR=Yes;IMEX=1";

用“ \”替换“ /”

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=https:\\d.docs.live.net\...\Documents\Financial Tracker.xlsb;Extended Properties="Excel 12.0;HDR=Yes;IMEX=1";`

在路径周围添加方括号

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=[https://d.docs.live.net/.../Documents/Financial Tracker.xlsb];Extended Properties="Excel 12.0;HDR=Yes;IMEX=1";

在路径周围添加引号

Provider=Microsoft.ACE.OLEDB.12.0;Data Source="https://d.docs.live.net/.../Documents/Financial Tracker.xlsb";Extended Properties="Excel 12.0;HDR=Yes;IMEX=1";

我意识到我可以通过在运行此代码时将其保存在本地，然后再将其保存回OneDrive来避免这种情况，但是我想尽可能避免这种情况。

我也意识到我可以编写VBA代码来完成我想用SQL进行的工作，但是我最初是这样做的，但是因为SQL更快，所以切换到了SQL方法。

这是我的代码：

Function OpenRST(strSQL As String) As ADODB.Recordset
''Returns an open recordset object

Dim cn As ADODB.Connection
Dim strProvider As String, strExtendedProperties As String
Dim strFile As String, strCon As String

strFile = ThisWorkbook.FullName

strProvider = "Microsoft.ACE.OLEDB.12.0"
strExtendedProperties = """Excel 12.0;HDR=Yes;IMEX=1"";"


strCon = "Provider=" & strProvider & _
     ";Data Source=" & strFile & _
     ";Extended Properties=" & strExtendedProperties

Set cn = CreateObject("ADODB.Connection")
Set OpenRST = CreateObject("ADODB.Recordset")

cn.Open strCon  ''This is where it fails

OpenRST.Open strSQL, cn

End Function

在cn.Open strCon行上，出现以下错误：

运行时错误'-2147467259（80004005）';
对象“ _Connection”的方法“打开”失败

谢谢！
