sql - 通过Microsoft Access创建表DDL

Question

有什么简单的方法可以从Microsoft Access（2007）中检索表创建DDL，还是我必须自己使用VBA对其进行编码以读取表结构？

我大约有30张表要移植到Oracle，如果可以从Access定义中创建表，将使工作变得更轻松。

感谢您的其他建议。在等待的过程中，我编写了一些VBA代码来做到这一点。这不是完美的，但是为我完成了工作。

         Dim fldDef As Field
         Dim FieldIndex As Integer
         Dim fldName As String, fldDataInfo As String
         Dim DDL As String
         Dim TableName As String

         TableName = TableDef.Name
         TableName = Replace(TableName, " ", "_")
         DDL = "create table " & TableName & "(" & vbCrLf
         With TableDef
            For FieldIndex = 0 To .Fields.Count - 1
               Set fldDef = .Fields(FieldIndex)
               With fldDef
                  fldName = .Name
                  fldName = Replace(fldName, " ", "_")

         End With
         DDL = DDL & ");"
         TableCreateDDL = DDL
End Function


Sub ExportAllTableCreateDDL()

    Dim lTbl As Long
    Dim dBase As Database
    Dim Handle As Integer

    Set dBase = CurrentDb

    Handle = FreeFile

    Open "c:\export\TableCreateDDL.txt" For Output Access Write As #Handle

    For lTbl = 0 To dBase.TableDefs.Count - 1
         'If the table name is a temporary or system table then ignore it
        If Left(dBase.TableDefs(lTbl).Name, 1) = "~" Or _
        Left(dBase.TableDefs(lTbl).Name, 4) = "MSYS" Then
             '~ indicates a temporary table
             'MSYS indicates a system level table
        Else
          Print #Handle, TableCreateDDL(dBase.TableDefs(lTbl))
        End If
    Next lTbl
    Close Handle
    Set dBase = Nothing
End Sub
