I am sorry but so no one knows if "run sums" is possible or even a good feature ?? Sorry for keep replying to this thread but i fail to see how this can not be a useful thing in many cases. See a similar SQL alternative: http://sqlfiddle.com/#!2/76f81/9 Rik van Bruggen recently posted this on h

Re: [Neo4j] Some basic questions about neo4j

1. you have to make sure that the server uses your data, so you have to copy the created directory to be named /path/to/neo/data/graph.db 2. in 1.9 you have to use start n=node(*) return n for all nodes or start n=node:nodes(name="Selina") return n.age see the cypher reference card for 1.9 http://
