对Cypher中相同节点的两个属性求和

Question

I can sum a property of all the node given from a cypher query. But ¿is it posible to sum two properties of the same node?

Example: MATCH (n: Node ) WITH na + nb as sum RETURN sum

UPDATE: Resolve in other comments, but if you want to get a sum of multiple properties of all nodes you can do:

MATCH (n:Node)
WITH sum(n.a + n.b) AS sum
RETURN sum

Answer 1

Yes, you can. In your example you could just do

MATCH (n:Node) RETURN n.a + n.b AS sum
