Question

I need to exclude first id entry, and display the rest on my wordpress, I have never used sql before.

$all_users_id = $wpdb->get_col( $wpdb->prepare("SELECT $wpdb->users.ID FROM $wpdb->users ORDER BY %s ASC", $sort ));

Answer 1

I am not familiar with WordPress, but try this:

$all_users_id = $wpdb->get_col( $wpdb->prepare("SELECT $wpdb->users.ID FROM $wpdb->users WHERE $wpdb->users.ID NOT IN (SELECT MIN($wpdb->users.ID) FROM $wpdb->users) ORDER BY %s ASC", $sort ));
