Re: [Neo4j] USING PERIODIC COMMIT LOAD CSV statement

Check the database logs and share the error? I presume you mean the Neo4j driver? Make sure you provide the csv data in the configured (in neo4j.conf) import directory. You might also have one slash too much. If you put your data into the import directory a file:///course.csv" should be good en

I don't think that the cypher run method returns a node in the first place. It returns a result object which you have to access to get its content. I'm not that well versed in py2neo, there might be other issues in the code example. Michael Von meinem iPhone gesendet > Am 11.09.2016 um 04:48
