Au cas où quelqu'un voudrait faire quelque chose de similaire, je publierai le code que j'ai écrit et testé au cours des cinq dernières heures.
J'ai décidé de convertir mes deux tables en trois, en déplaçant toutes les options récurrentes vers la troisième table :
'churchcal_events' - il y a des champs supplémentaires pour les informations sur l'événement que je n'ai pas inclus ici
+----+-----------+------------+------------+------------+-----------+
| id | name | date | starttime | endtime | recurring |
+----+-----------+------------+------------+------------+-----------+
| 1 | Event 1 | 2013-04-01 | 10:30:00 | 12:00:00 | 0 |
| 2 | Event 2 | | 14:00:00 | 15:00:00 | 1 |
| 3 | Event 3 | | 09:00:00 | | 1 |
| 4 | Event 4 | | 19:00:00 | 21:00:00 | 1 |
+----+-----------+------------+------------+------------+-----------+
'churchcal_assign' - achemine les événements vers les calendriers appropriés (car il y aura des calendriers pour différents départements sur l'ensemble du site Web)
+----------+-------------+
| event_id | calendar_id |
+----------+-------------+
| 1 | 1 |
| 2 | 1 |
| 3 | 1 |
| 4 | 1 |
+----------+-------------+
'churchcal_recur_events' - Voici les règles de récurrence de chaque événement
+----------+-----------+------------+----------------+------------+-------------+-----------+
| event_id | frequency | recur_type | recur_day_num | recur_day | recur_start | recur_end |
+----------+-----------+------------+----------------+------------+-------------+-----------+
| 2 | 1 | Week | NULL | Sunday | NULL | NULL |
| 3 | 2 | Week | NULL | Wednesday | 2013-04-01 | NULL |
| 4 | 2 | Month | third | Friday | 2013-04-01 | NULL |
+----------+-----------+------------+----------------+------------+-------------+-----------+

Si vous ne créez pas cela dans un module Drupal comme moi, vous pouvez remplacer 'db_query()' par votre propre fonction de requête de base de données comme la valeur par défaut de PHP 'mysql_query()';
