In my graph, relationships have a property named
list is an array of int.
It looks like this:
I'd like to query all tails in the graph, where the sum of
list is > 0.
Intuitively, I would do:
MATCH (:Node)-[r:RELATIONSHIP]->(tail:Node) WHERE sum(r.list) > 0 RETURN tail
This does not work unfortunately. It throws an error. How can I write this query?
