PowerDesigner 连接上数据库
创建数据库表 table_5


选择：

点击确认后弹出

点击run执行

刷新数据库表，已创建成功

修改测试表1，新增一个字段



取消全选

选择数据库，勾选修改的表，如果全部勾选的话，就会全部同步


就同步出来了

其他：打开注释
双击表打开表详情 ，选择columns

快捷键: Ctrl+U 找到注释并勾选

然后就出来：

一般注释与Name应该是联动的，所以可以执行脚本：
在PowerDesigner中打开脚本的方法为：
PowerDesigner->Tools->Execute Commands->Edit/Run Scripts

1　将comment覆盖name

注释联动脚本参考：PowerDesigner设计Name和注释相互替换
