在使用PowerDesigner對數據庫進行概念模型和物理模型設計時,一般在NAME或Comment中寫中文,在Code中寫英文。Name用來顯示,Code在代碼中使用,但Comment中的文字會保存到數據庫Table或Column的Comment中,當Name已經存在的時候,再寫一次Comment很麻煩,可以使用以下代碼來解決這個問題:
- 代碼一:將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_BatchDim 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
nextDim 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從數據庫反向生成PDM的時候,PDM中的表的NAME和CODE事實上都是CODE,爲了把NAME替換爲數據庫中Table或Column的中文Comment,可以使用以下腳本:
- 代碼二:將Comment中的字符COPY至Name中
Option Explicit
ValidationMode = True
InteractiveMode = im_BatchDim 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 IfPrivate 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
nextDim 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

以上兩段代碼都是VB腳本,在PowerDesigner中使用方法爲:
PowerDesigner->Tools->Execute Commands->Edit/Run Scripts
將代碼Copy進去執行就可以了,是對整個CDM或PDM進行操作
