有些時候我們的powerdesigner以jdbc的形式連結本地資料庫可能會失敗，這時候我覺得從sql檔案中生成物理模型是個很不錯的方法

1.開啟powerdesigner,檔案->->reverse engineer->->database

2.選擇對應的資料庫，我這裡以oracle11g為例，選擇share the DBMS defintion點選確定進入下邊的頁面

3.點選如上箭頭指示的按鈕新增要生成屋裡模型的sql檔案（就是建表語句，可直接從oracle中匯出），確定

4.但是生成的物理模型name是欄位名，不是我們想要的comment名，接下來進行如下操作 工具->execute commands->edit/Run script

5.貼上如下的命令並執行

    Option   Explicit   
    ValidationMode   =   True   
    InteractiveMode   =   im_Batch
    Dim blankStr
    blankStr   =   Space(1)
    Dim   mdl   '   the   current   model  
      
    '   get   the   current   active   model   
    Set   mdl   =   ActiveModel   
    If   (mdl   Is   Nothing)   Then   
          MsgBox   
 
"There   is   no   current   Model "   
    ElseIf   Not   mdl.IsKindOf(PdPDM.cls_Model)   Then   
          MsgBox   "The   current   model   is   not   an   Physical   Data   model. "   
    Else   
          ProcessFolder   mdl   
    End   If  
      
    Private   sub   ProcessFolder(folder)   
    On Error Resume Next  
          Dim   Tab   
 
'running     table   
          for   each   Tab   in   folder.tables   
                if   not   tab.isShortcut   then   
                      tab.name   =   tab.comment  
                      Dim   col   '   running   column   
                      for   each   col   in   tab.columns   
                      if col.comment = "" or replace(col.comment," ", "")="" Then
                            col.name = blankStr
                            blankStr = blankStr & Space(1)
                      else  
                            col.name = col.comment   
                      end if  
                      next   
                end   if   
          next  
      
          Dim   view   'running   view   
          for   each   view   in   folder.Views   
                if   not   view.isShortcut   then   
                      view.name   =   view.comment   
                end   if   
          next  
      
          '   go   into   the   sub-packages   
          Dim   f   '   running   folder   
          For   Each   f   In   folder.Packages   
                if   not   f.IsShortcut   then   
                      ProcessFolder   f   
                end   if   
          Next   
    end   sub  

6.搞定後效果如下
