I write this code but when I run it no output. There is no error but the problem no output.
How I can execute many queries in the same page?

First: there is an error. You are missing a where in the first query:
$query = "SELECT * FROM `student_record` id = 201102887;";
has to be:
$query = "SELECT * FROM `student_record` where id = 201102887;";
That is sufficient to have a blank screen.
For the rest your code is ok, in line with the classical example from:
http://php.net/manual/en/mysqli.multi-query.php
What I wonder is if you really configured your server to execute php inside html.
Put this part of your code with the above correction in a .php file and you will see results:
<?php
$link = mysqli_connect('localhost', 'root', '', 'uoh');
$query = "SELECT * FROM `student_record` where id = 201102887;";
$query .= "SELECT * FROM `course` where id = 201102887;";
if (mysqli_multi_query($link, $query)) {
do {
if ($result = mysqli_store_result($link)) {
while ($row = mysqli_fetch_array($result)) {
echo $row['code'];
echo $row['term'];
}
}
} while (mysqli_next_result($link));
}
/* close connection */
mysqli_close($link);
?>
I added the missing where and the closure of the connection.
By the way, I hope you are sure the records with those ids exist in your DB.
Just run your queries one by one using regular mysqli_query.
Leave multi_query alone, it is not for your case.
