第一步：将现有得数据表通过PowerDesigner导入sql脚本(同时保证注释不丢失及name code comment)
2.弹出弹窗对模型进行命名，同时在DBMS下拉选择框中需要选择自己对应的数据库类型，点击确定
3.新的弹窗，选中Using script files，再点击红圈中，选中你的sql脚本位置，点击确定
5.如何让Name里面的值显示的是comment里面的值
在使用REVERSE ENGINEER从数据库反向生成PDM的时候，PDM中的表的NAME和CODE事实上都是CODE，为了把NAME替换为数据库中Table或Column的中文Comment，可以使用以下脚本：
在PowerDesigner中使用方法为:
PowerDesigner->Tools->Execute Commands->Edit/Run Scripts
复制一下代码，点击RUN
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
