将多个访问表导出为单个XML

Question

我有多个Microsoft Access表,我想导出到一个XML文件.如何将表的顺序和层次结构操作到我想要的XML结构中？从本质上讲,我希望能够反转导入XML过程,该过程会自动将数据分解为多个表.我可以使用VBA,SQL和任何内置的导出功能.

Answer 1

我使用附件在大约五分钟内生成一个300万行嵌套xml.

有两个关键项目,

1)一个简单的VB,

Public Function Export_ListingData()

    Dim objOtherTbls As AdditionalData

    On Error GoTo ErrorHandle
    Set objOtherTbls = Application.CreateAdditionalData
    objOtherTbls.Add "ro_address"
    objOtherTbls.Add "ro_buildingDetails"
    objOtherTbls.Add "ro_businessDetails"
    objOtherTbls.Add "ro_businessExtras"
    objOtherTbls.Add "ro_businessExtrasAccounts"
    objOtherTbls.Add "ro_businessExtrasAccom"
    objOtherTbls.Add "ro_businessExtrasAccom2"

    Application.ExportXML ObjectType:=acExportTable, _
                DataSource:="ro_business", _
                DataTarget:="C:\Users\Steve\Documents\Conversions\ListData.xml", _
                AdditionalData:=objOtherTbls
Exit_Here:
        MsgBox "Export_ListingData completed"
        Exit Function
ErrorHandle:
        MsgBox Err.Number & ": " & Err.Description
        Resume Exit_Here
End Function

2)使用从主键到FOREIGN键的连接来链接关系管理器中的表.

如果没有关系,代码将生成顺序xml文件,如果主键之间存在关系,则会出现31532错误,数据导出将失败.

这是通过VBA的解决方案：
http ://msdn.microsoft.com/en-us/library/ff193212.aspx

创建一个 from 并在其上放置一个按钮。右键单击该按钮并选择“构建事件”并粘贴以下代码：

Dim objOtherTbls As AdditionalData


Set objOtherTbls = Application.CreateAdditionalData

'Identify the tables or querys to export
objOtherTbls.Add "internet"
objOtherTbls.Add "mokaleme"

'Here is where the export takes place
Application.ExportXML ObjectType:=acExportTable, _
DataSource:="internet", _
DataTarget:="C:\myxml.xml", _
AdditionalData:=objOtherTbls

MsgBox "Export operation completed successfully."

您必须在此处和引号之间输入表的名称：

   objOtherTbls.Add "internet"
    objOtherTbls.Add "mokaleme"

    DataSource:="internet"
