由於業務需要將數據庫裏面的表導出來生成pdm數據模型，於是查找了一下方法，總結步驟如下：
1、打開plSQL，上方工具欄tools->ExportUser Objects
2、選中你需要導出的表，選擇文件位置，導出SQL文件
3、打開powerDesigner，新建模型
4、選擇Model types ->Physical Data Modal ->Physical Diagram，自行修改文件名，保存
5、打開File->Reverse Engineer->Database
6、看到如下彈窗，點擊確定
7、 添加SQL文件，點擊運行
8、完成
9、 如果數據庫中的表有字段備註，希望直接用備註作爲名稱，可以打開Tools->Execute Comments->Edit/Run Script
10、 複製以下代碼到編輯器中：
Option Explicit
ValidationMode = True
InteractiveMode = im_Batch
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
' This routine copy name into code for each table, each column and each view
' of the current folder
Private sub ProcessFolder(folder)
Dim Tab 'running table
for each Tab in folder.tables
if not tab.isShortcut then
if tab.comment ="" then
else
tab.name=tab.comment
on error resume next
end if
Dim col ' running column
for each col in tab.columns
if col.comment="" then
col.name=col.name
else
col.name=col.comment
on error resume next
end if
next
end if
next
Dim view 'running view
for each view in folder.Views
if not view.isShortcut then
if view.comment="" then
view.name=view.name
else
view.name=view.comment
on error resume next
end if
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
11、運行，搞定
