Query SQL Database and Display PHP (Code Shown)

Hey everyone,

I need to query a table I made in my wordpress database. The code I have works.... BUT I want it to show the data based on the current users id.... this is what I have that works but doesn't filter based on users. It just displays everything.

global $wpdb;
$results = $wpdb->get_results("SELECT meta_key FROM wp_eddress_organisations WHERE meta_value = 1 ORDER BY meta_key");

if(!empty($results)) { foreach($results as $r) {
echo "<p>".$r->meta_key."</p>"; } } else { echo "<p>Nothing found!</p>";
}

This is what I tried but failed at lol global $wpdb;
$results = $wpdb->get_results("SELECT meta_key FROM wp_eddress_organisations WHERE meta_value = 1 AND user_id = <?php get_current_user_id(); ?> ORDER BY meta_key");

if(!empty($results)) { foreach($results as $r) {
echo "<p>".$r->meta_key."</p>"; } } else { echo "<p>Nothing found!</p>";
}
