Powerdesigner设计表生成SQL脚本（带有注释）

背景

​ 我们在PowerDesigner中设计好数据库表，并且每个表中的字段都会有相应的注释，可是在我们在导出sql语句后，却发现没有添加字段注释的相关sql语句（例如：EXECUTE sp_addextendedproperty N'MS_Description', N'字段注释', N'user', N'dbo', N'table', N'表名', N'column', N'字段名'）

解决方案

​ 步骤： Powerdesigner中选择Tools----->Excute commands---->Edit/Run Script 在打开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.
