PowerDesigner 把Comment写到name中 和把name写到Comment中 （转）

PowerDesigner 把Comment写到name中 和把name写到Comment中 pd7以后版本可用

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

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

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
         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
  
  ' 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
           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
  

   但是这个脚本有点不足之处：就是将name的内容完全覆盖在comments上。有一些我写好的comments会被覆盖了，这样很不爽。因此，在原脚本的基础上，我判断comments的长度大于name，不覆盖。这样自己写的comments就会保留下来。脚本。在表、视图的基础了，增加用户、表空间、序列等数据库对象的注释。

  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 not Len(tab.comment) > Len(tab.name) then
              tab.comment = tab.name
           end if
           Dim col ' running column
           for each col in tab.columns
              if not Len(col.comment) > Len(col.name) then
                 col.comment= col.name
              end if
           next
        end if
     next
  
     Dim view 'running view
     for each view in folder.Views
        if not view.isShortcut then
           if not Len(view.comment) > Len(view.name) then
              view.comment = view.name
           end if
        end if
     next
  
     Dim sequence 'running sequence
     for each sequence in folder.Sequences
        if not sequence.isShortcut then
           if not Len(sequence.comment) > Len(sequence.name) then
              sequence.comment = sequence.name
           end if
        end if
     next
  
     Dim myuser 'running user
     for each myuser in folder.Users
        if not myuser.isShortcut then
           if not Len(myuser.comment) > Len(myuser.name) then
              myuser.comment = myuser.name
           end if
        end if
     next   
  
     Dim tablespace 'running tablespace
     for each tablespace in folder.Tablespaces
        if not tablespace.isShortcut then
           if not Len(tablespace.comment) > Len(tablespace.name) then
              tablespace.comment = tablespace.name
           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

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
