oracle connecting interface吗？
好象是使用tcp/ip直接连接oracle rdbms的概念，完全不用中间件和客户端，在任意直接winsock的机器上就可以访问oracle数据库的东东吗？
我用odac做过这样的程序，800K的客户端，拷在一张软盘上，随处都可以利用这个客户端对远程的ORACLE数据库进行完全访问。
好象用就用过，不过关于OCI的文档没有仔细研究，都是OO的东东，没有过那个细啊！
文档我都有，全是洋文的，想要的话联系我
我找找，然后放在我的网站上，自己去找并DOWN

and update operations on a table column of type Nested Table:

推荐你用OTL（Oracle Templete Library）吧，很好用的!!
