Warning: Missing argument 2 for wpdb::prepare(), called in /home/barry/public_html/wp-content/themes/bordeaux/footer.php on line 23 and defined in /home/barry/public_html/wp-includes/wp-db.php on line 992

I checked on my theme code
For footer:
$google_loc = $wpdb->get_var($wpdb->prepare("SELECT post_content FROM $wpdb->posts WHERE post_type = 'boderaux_google_loc'"));

for bordeaux_menu.php

$count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(id) as Num FROM bordeaux_reservation WHERE approve=''"));

how can i fix this problem
