Ms access 如何循环访问MS Access数据库中的所有表

我需要读取Access 2003数据库中100多个表的属性，并将这些详细信息（表名、字段名、类型和大小）写入一个文件以供进一步的文档记录

我在网络搜索中找不到任何关于读取字段属性的信息，只找到字段值

有人能告诉我我必须声明哪些记录集变量（以及语法）才能循环遍历数据库中的所有表，并从每个表中提取字段名、类型和大小吗？我将把结果写入一个文本文件，但我想我能处理它！：）

在我解决这件事之前，我一直处于停顿状态。我花了一天的时间手动记录了两个表。有些表有超过100个字段。

您需要对此进行一些调整，它旨在将表从一个数据库复制到另一个数据库，但这应该是一个很好的起点

具有这些选项的数据库文档管理器向导应该以最少的工作量为您提供所需的内容

如果这种方法不令人满意，可以使用自定义VBA代码来收集所需的信息。通过循环DAO TableDefs集合，可以检索数据库中表的名称

Dim db作为DAO.Database
将tdf调暗为DAO.TableDef
Set db=CurrentDb
对于以db.TableDefs为单位的每个tdf
'忽略系统和临时表
如果不是（tdf.name如“MSys*”或tdf.name如“~*”），则
调试。打印tdf.name
如果结束
下一个
设置tdf=无
Set db=Nothing

要获得您想要的现场详细信息，请改编艾伦·布朗的。。。用文件写入语句代替

Debug.Print

语句。请注意，该函数使用了两个辅助函数，

getdescripp

和

FieldTypeName

，这两个函数都包含在链接页面中

这是我数据库中一个表的

TableInfo（）

的即时窗口输出示例，我想它包含了您想要的字段信息

TableInfo“foo”
字段名称字段类型大小说明
==========    ==========    ====          ===========
自动识别号码4
MyNumber长整数4
MyText文本255
条形长整数4
==========    ==========    ====          ===========

调整函数后，从上面示例中每个tdf的

循环调用它，并为每个
tdf提供它。name
：

TableInfo tdf.name
以下子项将所有表名、字段名、类型、必填项和默认值导出到excel工作表中

Sub TableDef()
 Dim def As TableDef
 Dim wb As Object
 Dim xL As Object
 Dim lngRow As Long
 Dim f As Field
 Set xL = CreateObject("Excel.Application")
 xL.Visible = True
 Set wb = xL.workbooks.Add
 lngRow = 2
 For Each def In CurrentDb.TableDefs
   For Each f In def.Fields
     With wb.sheets("Sheet1")
           .Range("A" & lngRow).Value = def.Name
           .Range("B" & lngRow).Value = f.Name
           .Range("C" & lngRow).Value = f.Type
           .Range("D" & lngRow).Value = f.Size
           .Range("E" & lngRow).Value = f.Required
           .Range("F" & lngRow).Value = f.DefaultValue
            lngRow = lngRow + 1
    End With
   Next
 Next
End Sub

谢谢你们两位。我知道我现在需要做什么了。好东西。
