PowerDesigner的ER图显示Comment注释

现在需要显示注释列，以便使得ER图更加清晰。但是PowerDesigner勾选Comment显示没有效果，所以通过以下几步来处理：

主要分三步：
1.表中添加对应的注释列，填写注释数据

2.在ER图显示出code列

3.将code列变为注释列的数据

第一步表中添加对应的注释列，填写注释数据

PowerDesigner默认显示的列是Name及类型，如下图示：

双击表，弹出表属性对话框，切到Columns，默认是没显示Comment的，显示Comment列，操作如下：

第二步在ER图显示出code列

确定保存，打开菜单 Tools>Display Perferences（工具–>显示首选项）

勾选name，调整code

确定后，如下

第三步将code列变为注释列的数据

打开菜单Tools>Execute Commands>Edit/Run Script.. 或者用快捷键 Ctrl+Shift+X，执行下面的代码：

目的是把comment注释覆盖到name字段

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

也可以把name字段覆盖到comment中（没用过）

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

确定后，如下：
