使用方法: 在E盘下面建立addm的目录，将三个文件放入到其中addm.cmd、addm.sql、myaddm.sql. 

  前提连上的用户需要被赋予两个权限。

        grant select any dictionary to user;-----user为生产数据库账号

        grant advisor to user;-------user为生产数据库账号

1. 文件名:addm.cmd       

 内容:  cmd.exe /c sqlplus username/password@servername @addm.sql

2. 文件名: addm.sql
