C++ 使用c++；错误106442000

当我想插入sql数据库时，我遇到了错误代码

错误：1064 sqlstate:42000

这是我的密码：

string* DB(string barcode)
{
    try {
        sql::Driver *driver;
        sql::Connection *con;
        sql::Statement *stmt;
        sql::ResultSet *res;
        /* Create a connection */
        driver = get_driver_instance();
        con = driver->connect("sql14.main-hosting.eu", "u103222348_user", "newsystem");
        /* Connect to the MySQL test database */
        con->setSchema("u103222348_read");

        stmt = con->createStatement();

        res = stmt->executeQuery("INSERT INTO 'Conveyor-BELT' ('BARCODE', 'TIM121') VALUES('5555','5555')");
        while (res->next()) {

            /* Access column data by alias or column name */


        }
        delete res;
        delete stmt;
        delete con;

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

    return EXIT_SUCCESS;
}

string*DB（字符串条形码）
{
试一试{
sql:：Driver*驱动程序；
连接*con；
sql:：语句*stmt；
sql:：ResultSet*res；
/*创建连接*/
driver=get_driver_instance（）；
con=driver->connect（“sql14.main hosting.eu”、“u103222348_user”、“newsystem”）；
/*连接到MySQL测试数据库*/
con->setSchema（“u103222348_read”）；
stmt=con->createStatement（）；
res=stmt->executeQuery（“插入‘传送带’（‘条形码’、‘TIM121’）值（‘5555’、‘5555’）”）；
while（res->next（））{
/*按别名或列名访问列数据*/
}
删除res；
删除stmt；
删除con；
}
捕获（sql:：SQLException&e）{
cout在MySQL中，使用反勾号转义列和表名，并使用引号转义字符串

INSERT INTO `Conveyor-BELT` (`BARCODE`, `TIM121`)
VALUES('5555', '5555')
