Re: [Neo4j] get all nodes and edges in a graph

Hi Wes, Thanks for the reply I think this should work. Just another quick question would be can we have any filters applied to the Edges. Just say the sample query would be " retrieve all edges which have ID more than 500(filter : ID >500) " or some thing similar to it. Thanks Puneet On Tuesda

[Neo4j] Combining two related yet distinct sets of data in one Neo4j graph database

Hello all, I am a Neo4j newbie and am using neo4j to model some clinical data. I'll refer to my graph db as the LC gdb. Further, the LC gdb will be influenced by another database from NIH I'll refer to as "NIH.SM. I decided to reformat the NIH.SM and import it into Neo4j for two reason

[Neo4j] get all nodes and edges in a graph

Hi, I am trying to get all nodes and edges of the graph. Though for the nodes I found a method getAllnodes() on GraphDatabaseService, it is deprecated. And for getting edges, I cannot find any method to call on the whole graph. I do not want to use traversal framework as graph can be disconnecte

Re: [Neo4j] Lost in "unable to commit transaction" errors, during move from 1.9.3 -> 2.0.0 (now all reads require transactions)

You need to call tx.success() at the end of the block rather than tx.finish(). The latter is done through the try-with-resources statement. For further details see the JavaDoc of the Transaction class, which explains this nicely with an example. On 12/31/2013 07:05 PM, M. David Allen wrote: As

Hi Javad I have made some adjustments to neotool ( http://book.py2neo.org/en/latest/neotool/) including a very basic shell mode with auth support. This was specifically to help support GrapheneDB so might be able to do what you want. Cheers Nigel On 31 December 2013 17:47, Javad Karabi wrote:

As I'm updating code for 2.0.0, I'm wrapping a lot of old code that only serves to inspect a graph (not update it) in transactions, using the new idiom: try ( Transaction tx = myDb.beginTx() ) { accessSomeData(); tx.finish(); } After the try block finishes, I'm getting exceptions of this

i guess i should elaborate... i need to connect to the neo4j service behind authentication, but neo4j-shell doesnt seem to have an option for username or password. does this mean neo4j-shell must be somehow wrapped in an auth mechanism? On Tuesday, December 31, 2013 11:38:45 AM UTC-6, Javad Karab

Just curious, what's the thinking behind requiring transactions for reads? Also, some documentation updates might be appropriate. For example: http://api.neo4j.org/current/org/neo4j/graphdb/NotInTransactionException.html public class NotInTransactionException extends RuntimeException

I'm in the middle of retrofitting neo4j code that was running on 1.9.3 to 2.0.0. This is all happening under windows, jdk1.7.0_45, and eclipse. I expected some teething problems and cut-overs; here's one I've run into: org.neo4j.graphdb.NotInTransactionException at org.neo4j.kernel.impl.p

Hi Luanne, If I'm using *SKIP* *12 LIMIT 25 *then I think it should return results starting from 13th to 25. If I'm right, then in this case why it is returning 25 rows? If I'm wrong, then how to get the results starting from 12 and ending with 25 (ie 13 rows)? -Sukaant Chaudhary On Tue, Dec 31,

Re: [Neo4j] Re: Please try this query in the given URL

Yes, irrespective of your skip, Limit 25 will return 25 rows if there are 25 rows to return. The only difference skip makes is whether to return 25 rows starting from the first record (skip 0) or 25 rows starting from the 13th record (skip 12). On Tue, Dec 31, 2013 at 3:53 PM, Sukaant Chaudhary <

[Neo4j] Re: Please try this query in the given URL

Yes 25 rows will be returned because that's the limit you set (assuming of course that you have more than 25 rows). If you want the "total no of rows which are in the limit" then limit 25 will give you 25 rows. Please see Skip: http://docs.neo4j.org/chunked/milestone/query-skip.htmland Limit: htt
