如何使用 VBA 从 MS-Excel (2010) 查询 MS-Access 表
我正在尝试在 Excel 中编写一些 vba 代码来查询 Access 中的表。我为此尝试了多个代码示例,例如添加的链接,它们似乎都在“打开连接”部分失败。我尝试过使用不同的引用,但我不确定应该使用哪个,某些不同版本之间的差异是什么(即 Microsoft ActiveX 数据对象 2.0,2.1,...,6.0)或提供程序信息是什么应该是。对于提供者信息,我通常会看到类似的内容
“Provider=Microsoft.Jet.OLEDB.4.0;数据源=”
但我不确定这是否是我需要使用的,或者为什么/什么条件上面显示的提供程序字符串中的任何内容应该改变。有人可以教育我如何正确地做这类事情吗?
注意:如果可能的话,我想要一个无需下载任何其他应用程序即可工作的解决方案,并且适用于 2007 和 2010 版本的 Access 和 Excel,因为这需要在具有可能不同版本的 Office 的不同计算机上运行。

代码:
Sub asdf()
strFile = "C:\Users\bwall\Desktop\Excel Query Access Testing"
Dim cn As Object
Dim rs As Object
Dim strSql As String
Dim strConnection As String
Dim AppPath As String
Set cn = CreateObject("ADODB.Connection")
AppPath = Application.ActiveWorkbook.Path
strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & AppPath & "\Masterlist_Current_copy.accdb;"
Debug.Print strConnection
strSql = "SELECT [Neptune Number],[Description],[Manufacturer],[Manufacturer P/N] FROM [All Components];"
cn.Open strConnection
Set rs = cn.Execute(strSql)
MsgBox rs.Fields(0) & " rows in MyTable"
rs.Close
Set rs = Nothing
cn.Close
Set cn = Nothing
End Sub
strConnection 值 =
Provider=Microsoft.Jet.OLEDB.4.0;数据 来源=C:\Users\bwall\Desktop\Excel 查询访问 测试\Masterlist_Current_copy.accdb;
I am trying to write some vba code in Excel to query a table in Access. I have tried multiple code samples for this such as the added links and they all seem to fail at the "Open connection" part. I have tried using different references but I'm not sure which I should be using, what the differences are between some of the different versions (ie. Microsoft ActiveX Data Objects 2.0,2.1,...,6.0) or what the provider information should be. For the provider information I've usually been seeing something along the lines of
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source="
But I'm not sure if that is what I need to use or why/what conditions anything in the provider string shown above should change. Can someone please educate me on how to properly do this sort of thing?
Note: If at all possible I would like a solution that would work without having to download any other application and would work for both 2007 and 2010 versions of Access and Excel since this will need to run on different computers with possibly different versions of office.

如果您的目标数据库是 ACCDB 格式,则 Provider 部分必须为
Provider=Microsoft.ACE.OLEDB.12.0
。Provider=Microsoft.Jet.OLEDB.4.0
仅适用于较旧的 MDB 格式。如果您运行的是 32 位 Windows,您甚至不需要安装 Access。 Jet 4 作为操作系统的一部分包含在内。如果您使用的是 64 位 Windows,则不包括 Jet 4,但您仍然不需要安装 Access 本身。您可以安装Microsoft Access Database Engine 2010 Redistributable。确保下载匹配的版本(AccessDatabaseEngine.exe 对于 32 位 Windows,或 AccessDatabaseEngine_x64.exe 对于 64 位)。
您可以通过使用后期绑定来避免有关 ADO 版本引用的问题,这不需要任何引用。
然后将 ConnectionString 属性分配给 conn 对象。下面是一个快速示例,它从 Excel 2003 中的代码模块运行,并显示一个包含 MyTable 行数的消息框。它对 ADO 连接和记录集对象使用后期绑定,因此不需要设置引用。
如果此答案无法解决问题,请编辑您的问题,向我们展示您尝试使用的完整连接字符串以及您在响应该连接字符串时收到的确切错误消息。
The Provider piece must be
Provider=Microsoft.ACE.OLEDB.12.0
if your target database is ACCDB format.Provider=Microsoft.Jet.OLEDB.4.0
only works for the older MDB format.You shouldn't even need Access installed if you're running 32 bit Windows. Jet 4 is included as part of the operating system. If you're using 64 bit Windows, Jet 4 is not included, but you still wouldn't need Access itself installed. You can install the Microsoft Access Database Engine 2010 Redistributable. Make sure to download the matching version (AccessDatabaseEngine.exe for 32 bit Windows, or AccessDatabaseEngine_x64.exe for 64 bit).
You can avoid the issue about which ADO version reference by using late binding, which doesn't require any reference.
Then assign your ConnectionString property to the conn object. Here is a quick example which runs from a code module in Excel 2003 and displays a message box with the row count for MyTable. It uses late binding for the ADO connection and recordset objects, so doesn't require setting a reference.
If this answer doesn't resolve the problem, edit your question to show us the full connection string you're trying to use and the exact error message you get in response for that connection string.
您所需要的只是一个 ADODB.Connection
All you need is a ADODB.Connection
