Trying CSV import to Neo4j - doesn't seem to be working.
I'm loading a local file using the syntax:
LOAD CSV WITH HEADERS FROM "file:///location/local/my.csv" AS csvDoc
Am wondering if there's something wrong with my CSV file, or if there's some syntax problem here.
If you didn't read the title, the error is:
Couldn't load the external resource at: file:/location/local/my.csv
[Neo.TransientError.Statement.ExternalResourceFailure]
回答1:
Neo4j seems to need a full path spec to get a file on the local system.
On linux or mac try
LOAD CSV FROM
"file:/Users/you/location/local/my.csv"
On windows try
LOAD CSV FROM
"file://c:/location/local/my.csv"
.

In the browser interface (Neo4j 3.0.3, MacOS 10.11) it looks like Neo4j prefixes your file path with $path_to_graph_database/import. So you could move your files there. If you are using a command line tool, then see this SO question.

Easy solution: Once you choose your database location (in my case ReactomeGraphDB60)... here I placed my ddbb ...go to that folder, and create inside a folder called "import".
Later in the cypher query write (as an example): LOAD CSV WITH HEADERS FROM "file:///ILClasiffStruct.csv" AS row CREATE (n:Interleukines) SET n = row
