为什么我不能在mysqli_multi_query之后运行mysqli_query？

Question

I have a problem with mysqli_multi_query. I tried to execute code but the mysqli_query after mysqli_multi_query doesn't work. $query1 update values and no return results.

if(mysqli_multi_query($con,$query1))
{
    $query2="insert into tablename values (1,2,3);";
    mysqli_query($con,$query2);
}

Try adding "trigger_error" to your query. It should show you what's happening wrong.

Like this:

mysqli_query($con,$query2) or trigger_error(mysqli_error($con));
