Yes, you're right.
Then, you have two options:
a) wait for the cleaning task to become active:
(defrule retract-them-all
(cleaning-time)
?x <- (MappingName)
=>
(rectract ?x))
b) Create a function to do it and invoke it when needed:
(defquery get-them-all
?f <- (MappingName))
(deffunction retract-them-all ()
(bind ?result (run-query* get-them-all))
(while (?result next)
(retract (?result get f)) ) )
Cheers,
Henrique
