打开查询功能不起作用

Question

<?php

if($connected=@fsockopen('www.google.com',80)){
$dbhost1 = "192.168.43.94";
    $dbuser1 = "root";
    $dbpassword1 = "";
    $db1 = "product";
    $connection1 = mysqli_connect($dbhost1,$dbuser1,$dbpassword1) or die (mysqli_error());
    mysqli_select_db($connection1,$db1);

    //MySQL Server 2
    $dbhost2 = "localhost";
    $dbuser2 = "root";
    $dbpassword2 = "";
    $db2 = "product";
    $connection2 = mysqli_connect($dbhost2,$dbuser2,$dbpassword2) or die (mysqli_error());
    mysqli_select_db($connection2,$db2);

    $sql="insert into 192.168.43.94.product.dbo.inserting select * from OPENQUERY(localhost,'select * from product.dbo.inserting')";
    $my=mysqli_query($connection2,$sql);
    if(!$my){
        echo 'Query failed'.mysqli_error();
    }
}
?>

我通过使用openquery语句（tcl）但它无法正常工作

我使用的是链接服务器。两种服务器是相同类型的服务器，具有相同的表结构
