C++中的存储过程如何调用？

#include <iostream>
#include <mysql_connection.h>
#include <cppconn/driver.h>
#include <cppconn/exception.h>
#include <cppconn/resultset.h>
#include <cppconn/statement.h>

int main() {
    try {
        sql::Driver *driver;
        sql::Connection *con;
        sql::Statement *stmt;
        sql::ResultSet *res;

        // 创建一个MySQL驱动
        driver = get_driver_instance();

        // 连接到数据库
        con = driver->connect("tcp://127.0.0.1:3306", "username", "password");

        // 选择数据库
        con->setSchema("your_database");

        // 创建一个语句对象
        stmt = con->createStatement();

        // 调用存储过程
        res = stmt->executeQuery("CALL your_stored_procedure('param1', 'param2')");

        // 处理结果
        while (res->next()) {
            std::cout << "Result: " << res->getString("column_name") << std::endl;
        }

        // 清理资源
        delete res;
        delete stmt;
        delete con;

    } catch (sql::SQLException &e) {
        std::cout << "# ERR: SQLException in " << __FILE__;
        std::cout << "(" << __FUNCTION__ << ") on line " << __LINE__ << std::endl;
        std::cout << "# ERR: " << e.what();
        std::cout << " (MySQL error code: " << e.getErrorCode();
        std::cout << ", SQLState: " << e.getSQLState() << " )" << std::endl;
    }

    return 0;
}
