Hello, I'm trying to use the CYPHER Reduce statement on the following:
Some nodes in the graph have properties: .A and .B which are numeric. For every node that has these properties, I want to take the absolute value of the difference between the two and sum across all nodes. I've tried the following: start c=node(*) match p=(c) where has(c.A) and has(.B) return reduce(total = 0, x in nodes(p)| total + abs(x.A - x.B)) as sum; But I get an error: "Don't know how to Subtract(Property..." Are the math operations something I'll have to do in a separate step? Thanks. -Patrick -- You received this message because you are subscribed to the Google Groups "Neo4j" group.
