用过OCCI的进来解答啊。

我运行demo的一段程序OCCI方式连接TimesTen11.2数据库，运行结果如下： 。不知道是否正确啊，貌似不对~~

源程序如下：
#include <iostream>
#include <occi.h>
using namespace oracle:cci;

    conn = env->createConnection (user, passwd, db);
  }

  ~test ()
  {
    env->terminateConnection (conn);
    Environment::terminateEnvironment (env);
  }

求高手解答！非常感谢！小弟刚入门~

提示很明显啊，你的tns名指定错了。

string db ="";
