18.2 Querying the Delete Log Database

This section describes how to query the delete log database.

To return entries from the Delete Log database, use the fetch_deletedcomponents WCAP command in either Expanded Mode or Compressed Mode.

The following information explains when and how to specify each mode.

• Expanded Mode (recurring = 0)

  If the recurring parameter is 0, fetch_deletedcomponents returns all instances of recurring events that match the criteria, but it does not return the master component for recurring events.

• Compressed Mode (recurring = 1)

  If the recurring parameter is 1, fetch_deletedcomponents returns non-recurring events and the master components for any recurring events, but it does not return individual recurring events.

  If all instances in a recurring chain are deleted, the master component returns the dtstart, dtend, rrules, rdates, exrules, exdates, and uid parameters.

  Also, the fetch_deletedcomponents command does not return master components associated with the deleted recurring instances that are still active. To return active master components, use the fetchcomponents_by_lastmod WCAP command. The fetch_deletedcomponents command should be used in conjunction with the fetchcomponents_by_lastmod command.
