PD中使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
' in version 7 and above.
' It always uses the object codes.
'
' In case the object codes are not aligned with your
' object names in your model, this script will copy
' the object Name onto the object Comment for
' the Tables and Columns.
'
'* Title:
'* Version: 1.0
'* Company: Sybase Inc.
'******************************************************************************

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

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
