PowerDesigner Name和Comment互相转化问题

  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
