When I processing negation query by SASE, it output all the results to negated matchs
The parser is not capable of handling filters like a.id = b.id
. For example, when parsing b.pizza_id = a.pizza_id
in the query query
PATTERN SEQ(order a, pizza b, item c)
WHERE skip-till-next-match
AND b.pizza_id = a.pizza_id
WITHIN 100
the program has defined the following variables:
left=b.pizza_id
right=a.pizza_id
newleft=pizza_id
newright=$1.pizz$1_id
predicate after parsing is: pizza_id = $1.pizz$1_id
Moreover, the answer to this query is always empty, even for streams with plenty of matches.
