Question

我正在尝试将记录从一个数据库复制到另一个数据库。两者都位于具有相同凭据的本地主机，只有数据库名称不同。在PhpMyAdmin中，我可以使用它，并且运行良好：

INSERT INTO warszawa.typy_pojazdow (typ, nazwa)
       SELECT type, description from rfid.vehicle_types

从php级别，我不知道如何在两个对象上同时运行该查询：

    $polaczenie = new mysqli($host, $db_user, $db_password, $db_name);
    $polaczenie2 = new mysqli($host, $db_user, $db_password, $db_name2);

    if ($polaczenie->connect_errno!=0)
    {
        echo "Error: ".$polaczenie->connect_errno;
    }
    else
    {
        $select = $polaczenie && $polaczenie2->query("INSERT INTO warszawa.typy_pojazdow (typ, nazwa ) SELECT type, description from rfid.vehicle_types");
    }

请帮助

如果同一个$ db_user可以访问两个数据库，则不需要2个连接。
