Ajout d'un champ Membership.created_at

[raphodn]

Suite de #566

Ce champ sera rempli à chaque création d'un nouveau membre.

Comment remplir ce champ pour les membres existants

les commandes suivantes sont à effectuer en SQL, directement sur votre base de données.

sortir d'abord quelques stats sur le nombre de membres concernés

SELECT COUNT(*) from membership;
SELECT COUNT(*) from membership where created_at = '0000-00-00 00:00:00';

solution 1 : les membres qui ont une date d'adhésion et une date de premier créneau

UPDATE membership m LEFT JOIN (SELECT r.membership_id, min(r.created_at) as min_registration FROM registration r GROUP BY r.membership_id) as min_r ON m.id = min_r.membership_id SET m.created_at = LEAST(min_r.min_registration, m.first_shift_date) WHERE (m.created_at = '0000-00-00 00:00:00' AND min_r.min_registration is not null AND m.first_shift_date is not null);

solution 2 : pour les membres restants (sans date d'adhésion, ou sans date de premier créneau)

UPDATE membership m LEFT JOIN (SELECT r.membership_id, min(r.created_at) as min_registration FROM registration r GROUP BY r.membership_id) as min_r ON m.id = min_r.membership_id SET m.created_at = min_r.min_registration WHERE (m.created_at = '0000-00-00 00:00:00' AND min_r.min_registration is not null AND m.first_shift_date is null);

UPDATE membership m LEFT JOIN (SELECT r.membership_id, min(r.created_at) as min_registration FROM registration r GROUP BY r.membership_id) as min_r ON m.id = min_r.membership_id SET m.created_at = m.first_shift_date WHERE (m.created_at = '0000-00-00 00:00:00' AND min_r.min_registration is null AND m.first_shift_date is not null);
