Oracle OCCI'選擇計數（*）'結果提取

Question

如何才能實現查詢執行結果 - select count (*) from myTable？ 的代碼是：

... 
oc::Statement* stmt = 
    m_cConnection->createStatement(select count (*) from myTable); 

oc::ResultSet* res = stmt->executeQuery(); 
... 

我怎樣才能獲得行計數的res價值？

Answer 1

只要寫

cout << res->getString(1) << endl; 

或

cout << "\t... MySQL counts: " << res->getInt(1) << endl;
