PowerDesigner 连接上数据库
创建数据库表 table_5


选择：

点击确认后弹出

点击run执行

刷新数据库表，已创建成功

修改测试表1，新增一个字段



取消全选

选择数据库，勾选修改的表，如果全部勾选的话，就会全部同步


就同步出来了

其他：打开注释
双击表打开表详情 ，选择columns

快捷键: Ctrl+U 找到注释并勾选

然后就出来：

一般注释与Name应该是联动的，所以可以执行脚本：
在PowerDesigner中打开脚本的方法为：
PowerDesigner->Tools->Execute Commands->Edit/Run Scripts

1　将comment覆盖name

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 NextDim   Tab   'running     table for   each   Tab   in   folder.tables if   not   tab.isShortcut   then tab.name   =   tab.commentDim   col   '   running   column for   each   col   in   tab.columns if col.comment="" thenelsecol.name=   col.comment end ifnext 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

2 将name覆盖comment

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 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

将code覆盖name

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 NEXTDim   Tab   'running     table for   each   Tab   in   folder.tables if   not   tab.isShortcut   then tab.name   =   tab.codeDim   col   '   running   COLUMN FOR   EACH   col   IN   tab.columns IF col.code="" THENELSEcol.name=   col.code END IFNEXT END   IF NEXTDim   VIEW   'running   view for   each   view   in   folder.Views if   not   view.isShortcut   then view.name   =   view.code 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

注释联动脚本参考：PowerDesigner设计Name和注释相互替换
