|Purpose||Deletes records from the spam filter database based on their last update time|
The DBDeleteTime statement requires a component name, comparator and time value, in the format
DBDeleteTime <component name> <comparator> <timevalue>
DBDeleteTime subject < "3 months"
This will delete all records for the 'subject' component which were last updated earlier than 3 months ago.
The SQL expression is created as 'updatetime <comparator> now() - <timevalue>', so the above statement's query string becomes
where updatetime < now() - '3 months'
