Hi guys!
I've got problems in my work with Neo4j, and if you please to help, I will
thank you a lot!
My work is something like this. I´ve got to study and evaluate several
graph databases, and to do that I must use a benchmark. The benchmark that
I'm used is the Social Network Benchmark (SNB)
I generate files with different setups, and all of them accordingly to the
setup choosed, got .csv extension. Something similar to this: forum_0.csv
This .csv files got certain headers, like this: id | title | creationDate |
The next step in my project is to load them to Neo4j, build a database to
test her with certain query’s, and my problems start here at this point.
I have loaded some files to Neo4j but others don't because of errors and I
don't understand why.
I'm using this code to load those files. In this example I load the
forum.csv to Neo4j.
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS
FROM ".../forum_0.csv" AS csvLine
FIELDTERMINATOR "|"
CREATE (:FORUM_0 {id:csvLine.id, title:csvLine.title,
creationDate:csvLine.creationDate})
And with this code, the data from this file is loaded to Neo4j correctly.
But with this file - forum_containerOf_post_0.csv I can´t load him correctly
(with this header - Forum.id | Post.id)
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS
FROM ".../forum_containerOf_post_0.csv" AS csvLine
FIELDTERMINATOR "|"
CREATE (:FCOP_0 {id1:csvLine.id, id2:csvLine.id})
The problem in here is I can´t access the id of forum_0.csv in the load
process of
forum_containerOf_post_0.csv. How can I access to that id, or another
property? Is the lack of some Cypher code?
Is there something wrong in the process? Is there someone here that work
with this - SNB and Neo4j?
Is there someone here to help me in this problem?
I tried to explain my problem but if you have questions about my problem,
feel free to ask.
Thank you for your time
Greetings
