For example, if you deleted a feed out of the feeds table, it would cascade that action down to any table that has feed_id as a foreign key (e.g. feed poll rolls, feed value tags, etc).&#xA;&#xA;It&#39;s to avoid the case where you&#39;ve deleted a feed_id from the feeds table, but other tables still reference that feed_id.</html></oembed>
