powerdesigner 将表中name列值复制到comment列 (保留原有comment)

/**
 * PowerDesigner里面将表中name列值复制到comment列
 * @see --------------------------------------------------------------------------------------------------------------------
 * @see pd中的pdm默认生成sql时,字段是没有注释的..想要注释的话,有2个方法
 * @see 1.也是推荐的
 * @see   pdm中双击打开一个Table,到Columns选项卡中,按快捷键Ctrl+U,找到Comment并勾选即可
 * @see   而且该操作设置一次就行了,以后在新的Table中也会自动出现Comment
 * @see   设置完毕后,在添加表字段时一并写上注释,这样生成的sql中字段就会有注释了
 * @see 2.执行vbs脚本
 * @see   相较第一种方法,该方法缺点是每次生成sql前,都要执行一遍这个脚本
 * @see   执行方式为Tools-->Execute Commands-->Edit/Run Scripts,或者直接快捷键Ctrl+Shift+X
 * @see   将下面的脚本拷进去执行一遍,也可以保存为name2comment.vbs(下一次再执行的话,就可以Ctrl+O再选择name2comment.vbs即可)
 * @see --------------------------------------------------------------------------------------------------------------------
