接下来是我自己总结的:

#include<stream.h>

#include
<string.h>

#include
<occi.h>

int main()

{

  Environment
*env;

   Connection
*con;

   Statement
*state;

  
string username="admin";

  
string pwd="123";

  
string db="123.123.123.123:1521/db"; //要查询的数据库地址和名字

  
*env = Environment::createEnvironment(Environment::Default);

  
*con = env->createConnection(username,pwd,db);

  
string sql = "select * from users";  //要查询的表
  
*state = con->createStatement(sql);

   ResultSet
*result = state->executeQuery();

  
while(result->next()) //将表内的信息查询出来

  {

    
int id=result->getInt(0);

    
string username=result->getString(1);

  }

  state
->closeResultSet(result);

  con
->terminateStatement(state);

  env
->terminateConnection(con);

  Environment::terminateEnvironment(env);

  
return 0;

}
