( *[1m *[m 為色碼，可以按 Ctrl+V 預覽會顯示的顏色 ) ( 未必需要依照此格式，文章條理清楚即可 ) 遇到的問題： (題意請描述清楚) 欲連到localhost的MYSQL伺服器, 經過一番努力總算是將complier完成但是在debug mode下會出現錯誤訊息而卡住不知道問題出在何方希望得到的正確結果：能正確連線至伺服器上作query 程式跑出來的錯誤結果：於 0x71bfb9f0 的 MYSQL Linking.exe 中發生未處理的例外狀況: 0xC0000005: 讀取位置 0xcccccccc 時發生存取違規開發平台： (例: VC++ or gcc/g++ or Dev-C++, Windows or Linux) windosws vista Visual studio 2005 C++ & mysql-connector-c++-1.0.5 有問題的code： (請善用置底文標色功能) /* Standard C++ includes */ #include <stdlib.h> #include <iostream> /* Include directly the different headers from cppconn/ and mysql_driver.h + mysql_util.h (and mysql_connection.h). This will reduce your build time! */ #include <mysql_driver.h> #include <mysql_connection.h> #include <cppconn/driver.h> #include <cppconn/exception.h> #include <cppconn/resultset.h> #include <cppconn/statement.h> using namespace std; using namespace sql; Driver *driver; Connection *con; int main(void) { cout << endl; cout << "Running 'SELECT 'Hello World!'
