sql – 从Microsoft Access创建表的DDL

有没有任何简单的方法从Microsoft Access(2007)检索表创建DDL,或者我必须使用VBA自己编写它来读取表结构？

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,这将使生活更轻松.

解决方法

感谢其他建议.当我在等待时,我写了一些VBA代码来做到这一点.这不是完美的,但为我做了工作.

         Dim fldDef As Field
         Dim Fieldindex As Integer

         TableCreateDDL = DDL
End Function


Sub ExportAllTableCreateDDL()

    Dim lTbl As Long

    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 _

             '~ indicates a temporary table
