使用powerDesigner反向工程生成Entity
由于业务需要将数据库里面的表导出来生成pdm数据模型，于是查找了一下方法，总结步骤如下：
1、打开plSQL，上方工具栏tools->ExportUser Objects
2、选中你需要导出的表，选择文件位置，导出SQL文件
3、打开powerDesigner，新建模型
4、选择Model types ->Physical Data Modal ->Physical Diagram，自行修改文件名，保存
5、打开File->Reverse Engineer->Database
6、看到如下弹窗，点击确定
7、 添加SQL文件，点击运行
8、完成
9、 如果数据库中的表有字段备注，希望直接用备注作为名称，可以打开Tools->Execute Comments->Edit/Run Script
10、 复制以下代码到编辑器中：
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、运行，搞定
