在使用PowerDesigner对数据库进行概念模型和物理模型设计时,一般在NAME或Comment中写中文,在Code中写英文。Name用来显 示,Code在代码中使用,但Comment中的文字会保存到数据库Table或Column的Comment中,当Name已经存在的时候,再写一次 Comment很麻烦,可以使用以下代码来解决这个问题
 

在PowerDesigner中使用方法为:

   PowerDesigner->Tools->Execute Commands->Edit/Run Scripts

将代码Copy进去执行就可以了,是对整个CDM或PDM进行操作

 
'代码一:将Name中的字符COPY至Comment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   comment   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   
                  tab.comment   =   tab.name   
                  Dim   col   '   running   column   
                  for   each   col   in   tab.columns   
                        col.comment=   col.name   
                  next   
            end   if   
      next  
  
      Dim   view   'running   view   
      for   each   view   in   folder.Views   
            if   not   view.isShortcut   then   
                  view.comment   =   view.name   
            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
 

另外在使用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:

      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

            if   not   tab.isShortcut   then

                  Dim   col   '   running   column
