在powerBuilder中新建一个Physical Data Model,在其中新建一个用户表,信息以下图所示:sql
此时的SQL语句可从其中的Preview视图中获得,以下图所示:数据库
这个时候生成的sql语句是没有注释的,并且sql语句可能也不是适合本身所对应的数据库语言。此时能够经过如下方法来生成注释而且选择所需的数据库语言。sqlserver
一、为sql生成注释,操做以下,我用的是PowerDesigner12.5,在其中选择Tools----》Excute commands-----》Edit/Run Script打开的窗口中添加如下信息ui
'****************************************************************************** '* 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 '把代表做为表注释,其实不用这么作 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
点击run后,能够看到刚刚的preview视图窗口中已经以下图所示this
二、更换数据库sql语句。code
选择Database---》change current DBMS,在DBMS中选择对应的数据库,如Microsoft SQL Server 2005,点击肯定后,而后选择Database---》Generate Database选项,在弹出的窗口中选择生成sql文件的保存路径,点击肯定,则可看到生成的sql语言彻底是按照sqlserver2005的标准。server
