从Microsoft Access创建表DDL

Question

有没有简单的方法从Microsoft Access(2007)检索表创建DDL或我是否必须使用VBA自己编写代码来读取表结构？

我有大约30个表,我们正在移植到Oracle,如果我们可以从Access定义创建表,它将使生活更轻松.

感谢您的其他建议.在我等待的时候,我写了一些VBA代码来做.这不是完美的,但为我做了这份工作.

Public Function TableCreateDDL(TableDef As TableDef) As String

         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)

                  fldName = .Name

               If FieldIndex > 0 Then

               DDL = DDL & "  " & fldName & " " & fldDataInfo
               Next FieldIndex
         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

我已经这样做了：

有一个工具可用于从 Access“升级”到 SQL Server。这样做，然后使用优秀的 SQL Server 工具生成脚本。
