Introducing Neo4j Workspace We’re inviting you to check out Neo4j Workspace. Workspace combines our most powerful graph tools (Data Importer, Bloom, and Browser) all in one place to help you get up and running with graph databases faster. For experie...
The Neo4j Graph Platform includes the core database and all the technologies surrounding the database, making it useful and accessible for a lot of different users. When asking a question, please select a descriptive label that best matches your quer...
I am reading data from a file and want to create nodes and relations between them. There is a chance that either of the two nodes of the relation are not existing by now. I solved this by: LOAD CSV WITH HEADERS FROM "foobar.csv" AS ROW MERGE (a:Typ...
I'm an old neo4j user. I started using neo4j around 2008 and suspend in 2014 due to health problems. Now I'm returning, installed the latest (?) community version with docker, and start my first task: importing 4 large excel tables into the DB, rest...
I am new to this group. Are there any Graph DB ETL tools that you can recommend? Thanks, Keith
Hi, I have a difficulty. My application uploads a file , and that file uploads the data in Neo4j database. In my Neo4j Application, i already have a database present and the file uploaded also makes its entries in the same database. That is the Datab...
I am trying out the pagerank which is in neo4j-graph-algorithms. My question is very specific: Is there a way to set the working precision for the algorithm execution? I am asking because I am comparing results from neo4j-algorithm with those from ot...
I am trying to randomly select / shuffle a group of nodes to set properties. What I currently have does this 19 times, but I just need it done once. This feels like a simple thing I am missing. UNWIND apoc.coll.shuffle(range(1,19,1)) AS value MATCH (...
I couldn't find it, but is there a way (function or procedure) to convert between a string character and its equivalent ASCII value?
I am looking at the point data type and I can see that it uses x,y,z and longitude,latitude,height interchangeably so I was wondering what is the intention behind this. I can see from the documentation that the intention seems to be to discriminate b...
Maybe someone can help me here. I am totally new to Neo4j. I have built a database with 3 different Nodes I now need to define the relationship between the data and like before I tested one relationship in the browser to ensure it works then moved ov...
Using apoc.periodic.iterate I need to create/update ~2M nodes. In the middle of data laoding process I see some transactions are rotated once they reach 250M of file size. This rotation takes for 1 or 2 hrs, till then am not able to use my browser o...
When I call a user-defined procedure that mutates the graph using the transactional http endpoint, the returned "stats" field doesn't reflect any of the changes that happened. For instance, when I call a procedure that deletes nodes and relationships...
Hi, I have created a network using the following queries - CREATE (cc:Organisation { name: "Century", dealing: "Cement", formed:1974 }); Match (cc:Organisation) WHERE cc.name = "Century" CREATE (eway:EwayBill {name:"EwayBill", type:"Outbound", conn...
Hi, I want to separate going in and going out relationships in a single cypher query, but it seems that I failed. My query is in this format: match (p:Person) where p.attribute = 'some attribute' with p match (p)-[r:Rel_A]->(d), (p)<-[s:Rel_A]-(c) re...
We've been slowly building up a Neo4j database (v.3.4.4 community edition) of genetic analyses. Up until the past week, we've been working with relatively small datasets and fleshing out the relationships, etc. Everything had been going quite well, s...
Hi all, I'm currently building a concept in Neo4j to store retail data, which in our case (as in most) includes products, articles/variants, stock-levels and pricelists. A product itself doesn't have a price until it's combined with a specific pricel...
