从Microsoft Access创建表DDL

谢谢你的其他建议。在我等待的时候,我编写了一些VBA代码来实现它。它并不完美,但为我完成了任务。

Option Compare Database
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)
               With fldDef
                  fldName = .Name
                  fldName = Replace(fldName, " ", "_")
                  Select Case .Type
                     Case dbBoolean
                        fldDataInfo = "nvarchar2"
                     Case dbByte
                        fldDataInfo = "number"
                     Case dbInteger
                        fldDataInfo = "number"
                     Case dbLong
                        fldDataInfo = "number"
                     Case dbCurrency
                        fldDataInfo = "number"
                     Case dbSingle
                        fldDataInfo = "number"
                     Case dbDouble
                        fldDataInfo = "number"
                     Case dbDate
                        fldDataInfo = "date"
                     Case dbText
                        fldDataInfo = "nvarchar2(" & Format$(.Size) & ")"
                     Case dbLongBinary
                        fldDataInfo = "****"
                     Case dbMemo
                        fldDataInfo = "****"
                     Case dbGUID
                        fldDataInfo = "nvarchar2(16)"
                  End Select
               End With
               If FieldIndex > 0 Then
               DDL = DDL & ", " & vbCrLf
               End If
               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

我已经做到了:

有一个工具可以从访问SQL Server“升迁”。这样做,然后使用优秀的SQL Server工具生成脚本。

有一个关于将Access数据库转换为Oracle的完整教程 here . 如果这只是你想要的结构,那么你可以专注于第3.0节。

可以使用Access中的导出功能将表导出到ODBC数据源。将ODBC数据源设置为Oracle数据库,然后右键单击Access“Tables”选项卡中的表并选择导出。ODBC是“文件格式”之一,它将打开通常的ODBC对话框。

您可能需要查看ADOX以获取模式信息。使用ADOX,您可以获得诸如键、视图、关系等内容。

不幸的是,我不是一个VB程序员,但是网上有很多使用ADOX获取表格模式的例子。

派对有点晚了,但我使用RazorSQL为Access数据库生成DDL。
