+-- mrbs/purge.my.sql 2001-01-13 : Purge old MRBS entries, for MySQL
+--
+-- This SQL script will delete old entries from your MRBS database.
+-- By default, entries which ended 30 days or more in the past will be removed,
+-- Repeat table records with no corresponding entry records will be removed.
+--
+-- If old entries get purged from a series, then somebody edits the series,
+-- the old entries will be re-created unless they change the start date on
+-- the form. Fixing this would require changing the start_time and end_time
+-- in the repeat record to match oldest undeleted entry; this is left as an
+-- exercise to the reader.
+--
+-- If you have decided to change the prefix of your tables from 'mrbs_'
+-- to something else then you must edit each 'DELETE FROM' line below.
+--
+-- MySQL Notes:
+-- To change the number of days, edit BOTH places below.
+--
+-- Because MySQL lacks sub-selects, I can't use SQL to remove orphan repeat
+-- entries. (See purge.pg.sql for the "right way".) Instead, this removes
+-- records from the repeat table based on their repeat end_date, which is
+-- close enough to be almost the same thing.
+
+DELETE FROM mrbs_entry
+WHERE end_time < unix_timestamp(date_sub(current_timestamp, interval 30 day));

+DELETE FROM mrbs_repeat
+WHERE end_date < unix_timestamp(date_sub(current_timestamp, interval 30 day));
