Good point. I'd believe that thinking of a single node as a degenerated path wouldn't be that wrong either. However, even returning just the callee (which is what I wanted anyways) brings no relief, with the relationship direction having no influence: 08:42:33,150 GraphQuery.java 81 INFO -

Did you try the query I gave you? The problem is not that you are returning p, it's that you ask Cypher to create a path with nulls in it. Just remove the p= in the beginning of the MATCH clause, and you should be good to go. Andrés On Sat, Nov 5, 2011 at 8:45 AM, jschweigl

Stupid me. Sorry. I should have copypasted your query. Yes, without the path assignment it works. Thanks a lot! -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Cypher-question-tp3479960p3482176.html Sent from the Neo4j Community Discussions mailing list

+1 I love Cypher's ASCII art, and Josh's idea of drawing Cypher inside a whiteboarded graph is wonderful. I really don't want Cypher to pander to SQL. Cypher is about graph matching and should be awesome at it - its duty to us newbies is simply to be humane not identical to what I (think I)

You'd have to go with another solution then. Is your application this critical to write throughput or are you just thinking ahead and making sure that it some day might need to support an amount of write throughput? 2011/11/3 Yaniv Ben Yosef yani...@gmail.com Hi, I've also been wondering

People already familiar with graphs seem to love the original Cypher syntax while newbies may find it helpful to start with something they already know. What about letting both coexist peacefully? Axel Am 05.11.2011 14:29, schrieb Andres Taylor: On Nov 5, 2011 1:51 PM, Jim

newbies may find it helpful to start with something they already know. One problem with this is that it could invoke a tendency to try to map relational concepts onto a graph db. The two types of database are fundamentally different at the lowest level and if one starts off by thinking where do I

FWIW, you might be better off pipelining these writes through a single worker thread/queue. It helps with a few performance issues: 1) you can avoid synchronization concerns 2) you can manage block writes (e.g. a number of writes in a single transaction) more easily and 3) you can (if you

Oh, and one more benefit - if you want to implement a distributed/sharded storage engine, this abstraction through a write queue makes it much, much simpler and more transparent to the application. From: user-boun...@lists.neo4j.org

This issue was unintentionally introduced along with some changes needed for better control and output from the windows wrapper. It was a regression that has now been fixed. I would suggest either - waiting for the next release, or - if you are feeling adventurous, download a snapshot windows

IMHO, the differential key of Cypher regarding to SQL, is the way in which Cypher builds the joins. I mean, the clause PATTERN or WHERE written like lucy-[:ACTS_IN]-movie-[:ACTS_IN]-co_actor is pretty powerful. The rest of the details are unimportant, in the sense they already have an equivalence
