PowerDesigner数据库设计PDM基于Excel的导入导出总结

　　经常用到pdm来管理代码，一两张表，手写一下还凑合，一旦表多了，就慌了。于是，开始学习用vbs进行Excel的来快速导入导出操作PDM就变得很紧急了，搜罗了网络上的很多vbs脚本，各有各的优点，但对于我来说都不太理想，遂基于网络的版本，改造了合适自己版本，本文就是基于网上的代码进行总结。

　　在数据库建模中会用到Powerdesigner软件进行表结构的设计，有时候我们需要将Excel里面的表结构导入到Powerdesigner中生成PDM模型文件，或者将Powerdesigner中已有的PDM模型导出生成Excel文档；我们可以通过Powerdesigner的脚本定制功能，来实现Excel的导入导出。

 

在PowerDesigner 中 ctrl+shift+x 弹出执行脚本界面，输入如下代码就会生成 Excel，前三个代码为导出，最后一个为基于Excel导入表结构
