How to fetch values for every id present in array using loop

Question

I have an array with following values:

$test = [2,8,10,12]; 

and a table 'orderdetails' in database with order_title and order_id columns.

What I want is to fetch order_title of every order using order_id in a loop. Can anyone help?

What I know is:

$test = [2,8,10,12];
foreach($test as $order_id){
$order_name = $wpdb->get_results('SELECT order_title FROM orderdetails WHERE order_id ='. $order_id);
$order_names[] = $order_name;
}

but this will make query run multiple times, any better solution?

UPDATE:

When I try to use IN(), values are getting inserted like this:

SELECT order_title FROM orderdetails WHERE order_id IN(2,8,10,12)

but what problem is here, query is only returning the value for first element in array that is 2

the solution needs to get applied is IN('2','8','10','12') all the values should be in a single quote, but I don't know how to achieve that.

Answer 1

I'd do it like this:

$test = [2,8,10,12];
$inclause = '';
foreach($test as $order_id){
    $inclause .= $order_id . ',';
}
$inclause = rtrim($inclause,',');
$query = 'SELECT order_title FROM orderdetails WHERE order_id IN ('. $inclause . ')';
$order_name = $wpdb->get_results($query);
