使用PD进行数据模型设计时 使name和comment关联

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:

  • 代码一:将Name中的字符COPY至Comment中
    '******************************************************************************
    '*   File:           name2comment.vbs
    '*   Purpose:     Database   generation   cannot   use   object   names   anymore

    '                         It   always   uses   the   object   codes.

    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:

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


以上两段代码都是VB脚本,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
