PowerDesigner使用技巧

name 填充到 comment

把 pd 中 name 的值自动添加到 comment 里面（如果 comment 为空，则填入 name，否则保留不变），这样可以避免已有的注释丢失。通过 Shift + Ctrl + x 快捷方式打开脚本运行窗口执行以下脚本（vb.net 语法）：

Option Explicit
ValidationMode = True
InteractiveMode = im_Batch

Dim mdl ' the current model
Set mdl = ActiveModel  ' get the current active model

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
	        if trim(tab.comment)="" then ' 如果有表的注释,则不改变它. 如果没有表注释,则把name添加到注释里面
	            tab.comment = tab.name
	        end if
	
	        Dim col ' running column
	        for each col in tab.columns
	            if trim(col.comment)="" then  '如果col的comment为空,则填入name. 如果已有注释,则不添加;这样可以避免已有注释丢失. 
	                col.comment= col.name
	            end if
	        next
	    end if
	next
	
	Dim view 'running view
	for each view in folder.Views
	    if not view.isShortcut and trim(view.comment)="" 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

生成数据库脚本

通常情况下我们需要把 pd 中的 PDM（Physical Data Model）导出为我们需要数据库的脚本，各个数据库脚本大同小异，下面以 Sql Server 为例：
打开路径：Database > Edit Current DBMS > General > Script > Objects

表注释生成语句

Table > TableComment

EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N%.60qA:COMMENT%, @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'[%QUALIFIER%]%TABLE%'
GO

列注释生成语句

Column > ColumnComment

EXEC sys.sp_addextendedproperty @name=N'MS_Description', @value=N%.60qA:COMMENT% , @level0type=N'SCHEMA',@level0name=N'dbo', @level1type=N'TABLE',@level1name=N'[%QUALIFIER%]%TABLE%' , @level2type=N'COLUMN',@level2name=N'%COLUMN%'
GO
