{0C733AA7-2A1C-11CE-ADE5-00AA0044773D}

Command objects support ICommandPersist for persisting the state of a command object. Persisting a command object does not persist any active rowsets that may have resulted from the execution of the command object, nor does it persist accessors, property settings, or parameter information associated with the command object.
