有些时候我们的powerdesigner以jdbc的形式链接本地数据库可能会失败，这时候我觉得从sql文件中生成物理模型是个很不错的方法
1.打开powerdesigner,文件->->reverse engineer->->database
2.选择对应的数据库，我这里以oracle11g为例，选择share the DBMS defintion点击确定进入下边的页面
3.点击如上箭头指示的按钮添加要生成屋里模型的sql文件（就是建表语句，可直接从oracle中导出），确定
4.但是生成的物理模型name是字段名，不是我们想要的comment名，接下来进行如下操作 工具->execute commands->edit/Run script
5.粘贴如下的命令并执行
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.搞定后效果如下
