PowerDesigner导出SQL时自动生成注释

PowerDesigner导出SQL时⾃动⽣成注释
在powerBuilder中新建⼀个Physical Data Model，在其中新建⼀个⽤户表，信息如下图所⽰：
此时的SQL语句可从其中的Preview视图中得到，如下图所⽰：
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
ment =
Dim col ' running column
for each col in tab.columns
'把列name和comment合并为comment
ment=
next
end if
next
Dim view 'running view
for each view in folder.Views
if not view.isShortcut then
ment =
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
点击run后，可以看到刚刚的preview视图窗⼝中已经如下图所⽰
2、更换数据库sql语句。

选择Database---》change current DBMS,在DBMS中选择对应的数据库，如Microsoft SQL Server 2005，点击确定后，然后选择Database---》Generate Database选项，在弹出的窗⼝中选择⽣成sql⽂件的保存路径，点击确定，则可看到⽣成的sql语⾔完全是按照sqlserver2005的标准。
