How to run SQL query from WordPress ‘WP Crontrol’ plugin

I managed to get things working by using:

include_once("wp-config.php");
include_once("wp-includes/wp-db.php");

global $wpdb;

$sql = "UPDATE wp_pmpro_memberships_users
SET wp_pmpro_memberships_users.status="admin_cancelled"
WHERE wp_pmpro_memberships_users.user_id IN 
    (
    /*Select all users that have an active Membership but no active Subscription*/
    SELECT pmpro.user_id FROM wp_pmpro_memberships_users as pmpro
    JOIN wp_pmpro_membership_levels as pmprol ON pmprol.id=pmpro.membership_id
    JOIN wp_users ON pmpro.user_id = wp_users.ID
    WHERE pmpro.status="active"
    AND pmpro.user_id NOT IN 
        (
        /*Select all users that have an active Subscription*/
        SELECT meta.meta_value 
        FROM wp_posts as p
        JOIN wp_postmeta as meta
        ON meta.post_id = p.id
        JOIN wp_users as u
        ON meta.meta_value = u.id
        WHERE post_type LIKE 'shop_subscription'
        AND post_status LIKE 'wc-active'
        AND meta.meta_key = '_customer_user'
        )
    )";
    
$results = $wpdb->get_results($sql);
