PowerDesigner生成注释以及对应数据库的sql语句

这个时候生成的sql语句是没有注释的，而且sql语句可能也不是适合自己所对应的数据库语言。此时可以通过以下方法来生成注释并且选择所需的数据库语言。

1、为sql生成注释，操作如下，我用的是PowerDesigner12.5,在其中选择Tools----》Excute commands-----》Edit/Run Script打开的窗口中添加以下信息

'******************************************************************************

'* 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

'把表明作为表注释，其实不用这么做

tab.comment = tab.name

Dim col ' running column

for each col in tab.columns

'把列name和comment合并为comment

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

1. 生成sql脚本的时候，提示"constraint name uniqueness”

解决方式：菜单 Model --> References 对话框中的"FK constraint Name”列，在这里找到名称重复的名称，修改为不同名称。
