批量生成Oracle DDL文件程序(Jython+zxJDBC版)

批量生成Oracle DDL文件程序(Jython+zxJDBC版)

之前写了一个批量生成Oracle DDL文件的Python程序(链接 http://www.cnblogs.com/harrychinese/archive/2011/10/12/My_First_Python_App_To_Generate_Oracle_DDL.html), 是CPython+cx_Oracle, 我的Windows一直没有装好cx_Oracle, 每次使用这个程序, 都需要登录到Linux上, 很不方便.

今天用Jython2.5.2+zxJDBC重新实现了, zxJDBC是Jython标准库, 装好Jython就有了.  之前那个版本是基于Python2.7, 因为Jython是2.5.2, 需要简单修改点语法, 另外zxJDBC不支持user/pwd@tns的连接写法, 所以对connection这块也要修改一下.
