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：
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 ExplicitValidationMode = TrueInteractiveMode = im_BatchDim mdl ' the current model' get the current active model Set mdl = ActiveModel If (mdl Is Nothing) ThenMsgBox "There is no current Model "ElseIf Not mdl.IsKindOf(PdPDM.cls_Model) ThenMsgBox "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 nextend ifnextDim view 'running view for each view in folder.Views if not view.isShortcut then view.comment = view.name end ifnext' go into the sub-packages Dim f ' running folder For Each f In folder.Packages if not f.IsShortcut then ProcessFolder f end ifNextend 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。如下图所示：
