使用PowerDesigner对NAME和COMMENT互相转换

使用PowerDesigner对NAME和COMMENT互相转换

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：

代码二:将Comment中的字符COPY至Name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

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="" then
  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
