-- Description: (1) Writes the execution times of deleted jobs into DeletedJobStats to ensure correct statistics
--        (2) Deletes all associated jobs. This cannot be done with cascading delete, 
--              because the job table defines a INSTEAD OF DELETE trigger itself, which
--              is not compatible with cascading deletes.
