誰かが同様のことをしたい場合は、私が作成してテストしたコードを過去5時間以内に投稿します。
2つのテーブルを3つに変換し、すべての定期的なオプションを3番目のテーブルに移動することにしました。
'churchcal_events' -ここに含めていないイベント情報の追加フィールドがあります
+----+-----------+------------+------------+------------+-----------+
| 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' -イベントを適切なカレンダーにルーティングします（Webサイト全体にさまざまな部門のカレンダーがあるため）
+----------+-------------+
| event_id | calendar_id |
+----------+-------------+
| 1 | 1 |
| 2 | 1 |
| 3 | 1 |
| 4 | 1 |
+----------+-------------+
'churchcal_recur_events' -各イベントの再発のルールは次のとおりです
+----------+-----------+------------+----------------+------------+-------------+-----------+
| 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 |
+----------+-----------+------------+----------------+------------+-------------+-----------+
新しいコード（PHP） -これは1日ループです

私のようにDrupalモジュールでこれを作成していない場合は、「db_query（）」をPHPのデフォルトの「mysql_query（）」のような独自のデータベースクエリ関数に置き換えることができます。
