PowerDesigner技巧集1

1. Name与Code同步的问题

   PowerDesigner中，修改了某个字段的name，其code也跟着修改，这个问题很讨厌，因为一般来说，name是中文的，code是字段名。

   解决方法如下：

   1、选择Tools->GeneralOptions...菜单，出现General Options对话框。

   2、从Category中选择Dialog项。

   3、取消右边"Name to Code mirroring"复选框。如下图：

   

    

2. 批量根据对象的name生成comment的脚本

   执行方法：PD12 à Open PDM à Tools à Execute Commands à Run Script

   这是网络上下载的脚本
   
   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 code 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
   
   

   但是这个脚本有点不足之处：就是将name的内容完全覆盖在comments上。有一些我写好的comments会被覆盖了，这样很不爽。因此，在原脚本的基础上，我判断comments的长度大于name，不覆盖。这样自己写的comments就会保留下来。脚本。在表、视图的基础了，增加用户、表空间、序列等数据库对象的注释。
   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 code 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 if not Len(tab.comment) > Len(tab.name) then tab.comment = tab.name end if Dim col ' running column for each col in tab.columns if not Len(col.comment) > Len(col.name) then col.comment= col.name end if next end if next Dim view 'running view for each view in folder.Views if not view.isShortcut then if not Len(view.comment) > Len(view.name) then view.comment = view.name end if end if next Dim sequence 'running sequence for each sequence in folder.Sequences if not sequence.isShortcut then if not Len(sequence.comment) > Len(sequence.name) then sequence.comment = sequence.name end if end if next Dim myuser 'running user for each myuser in folder.Users if not myuser.isShortcut then if not Len(myuser.comment) > Len(myuser.name) then myuser.comment = myuser.name end if end if next Dim tablespace 'running tablespace for each tablespace in folder.Tablespaces if not tablespace.isShortcut then if not Len(tablespace.comment) > Len(tablespace.name) then tablespace.comment = tablespace.name end if 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
