问题 I am trying to figure out the way to retrieve node by id. MATCH (n) WHERE ID(n) = {id} RETURN n , is the Cypher I used with REST interface. Now using fluent syntax of Neo4j Client for .net I cannot find the function name in Neo4J.Cypher namespace, like for instance ALL. Anybody knows how to re-write that query in fluent syntax? client.Cypher .Match("(node:Employee)") .Where(node=>**?**(node)== 3) .Return(node) 回答1: There is no ID function name in the codebase, so you have to go old skool I'm

问题 I want to use Neo4j to store a number of graphs I created in python. I was using Gephi for visualization, and I thought the export to Neo4j plugin would be a very simple way to get the data across. The problem is that the server is seemingly not recognizing the neostore...db files that Gephi generated. I'm guessing I configured things incorrectly, but is there a way to fix that? Alternatively, I'm also open to importing the files directly. I have two files: one with node titles and attributes

问题 I am new to Cypher. I was able to create a network of geographies (from the World to continents to countries to regions) and their population. You can reproduce it with this command or check the link to the console: http://console.neo4j.org/r/dkh90c CREATE (n1:Geo {name:'World'}), (n2:Geo {name:'EMEA'})-[:BELONG_TO]->(n1), (n4:Geo {name:'NORAM'})-[:BELONG_TO]->(n1), (n5:Geo {name:'Middle East'})-[:BELONG_TO]->(n2), (n6:Geo {name:'Africa'})-[:BELONG_TO]->(n2), (n7:Geo {name:'Europe'})-[:BELONG

问题 I am building an application where node labels, parameters and relationships are going to be set by my users, so nodes, rel, and prop after a certain layer will be completely dynamic and unpredictable. My question is how do I run the following query and map the results to some sort of list that can be used to rebuild the graph visually. Using neo4jClient. The query I use directly with the Neo4j Browser works great Match(a:User),(b:Work)-->(n) Where a.UserId = 'xxxx' AND b.Name = 'CompanyA'

问题 When running the neo4j server in Linux, we have several commands - start, stop, restart, etc - to control it via the command line. In windows, the manual simply says: Usage - Windows Neo4j.bat Double-clicking on the Neo4j.bat script will start the server in a console. To quit, just press control-C in the console window. But how do I stop it if I've started it by executing neo4j.bat from a .bat file of my own, and thus don't have a console window? For context: I'm working on an unmanaged
