When I create a file in centos using java,
File file= new File("file.txt"),
it creates a directory with the name file.txt. When I manually created a file in the directory so that atleast it overwrites the existing file and identifies it as a file, it is not able to overwrite.It says file already exits as a result of which it stops writing into the file.
WITH "/Users/nlp/social_graph/graph-nodes.csv" as uri
LOAD CSV WITH HEADERS FROM uri as row
MERGE (:User {id: row.id})
I have a CSV file to contains some nodes, and I want to load it into neo4j through Neo4j Desktop, but got the following error message:
Invalid URL '/Users/nlp/social_graph/graph-nodes.csv': no protocol: /Users/nlp/social_graph/social-nodes.csv
What's the error? Note that before I run the command in the browser, the database is empty. How to load the database?
EDIT: Did some search and added 'file:///' to the file path, this time I got another message:
Couldn't load the external resource at: file:/Users/congminmin/Library/Application%20Support/Neo4j%20Desktop/Application/neo4jDatabases/database-fdb13bea-33f7-409b-a6bd-387a25a679e6/installation-3.5.12/import/Users/congminmin/social_graph/social-nodes.csv
The easiest would be to copy your cv file into the import directory under your neo4j installation directory. Then use file:///social-nodes.csv In your LOAD CSV command.

I know it's late, but if you are using neo4j on docker, the import folder path is as follows:
/var/lib/neo4j/import
You can create a volume that bounds to the import directory. After mounting, copy your local files to your mounted directory, then use file:///file-name in your LOAD command.
I have some doubt on SSIS package.
I want to unzip multiple file and load in MSSQL table, all the file having different schema.
i need to it in 1 package.
Can this possible?
I'm trying to load a CSV file into Neo4j Enterprise edition and I think I'm considering all the rules but I don't understand what is the error related to
this is the error :
this is my csv file . I have entered my data in excel and then saved it as a CSV file :
Copy your CSV file to Neo4j Import Directory. Take a look in Neo4j file locations docs. For windows desktop installations this directory is %APPDATA%\Neo4j Community Edition\import.
Change your import path to 'file:///abc.csv'
Try again.

update1: I have tried to found conf/neo4j-server.properties but i don't have...
this is a screenshot of my folder ne04j (It is in Windows document Folder)

Neo4J databases live in your filesystem, you can simply make a copy of the folder in which your Neo4J data is stored. If you are running standalone this folder will be configured in conf/neo4j-server.properties and the line will look something like this:
org.neo4j.server.database.location=data/graph.db
Copy the content of that folder to the graph database folder on your other machine. I'd recommend that your databases are not running when you do this.
I believe you're looking for the dump shell command which you can use to export a database into a single Cypher create statement, you'd "dump" the database and then import it on your new machine.
Information on using the command is outlined here: Neo4j docs
A Neo4j database can be dumped and loaded using the following commands:
neo4j-admin dump --database=<database> --to=<destination-path>
neo4j-admin load --from=<archive-path> --database=<database> [--force]
Limitations
The database should be shutdown before running the dump and load commands.
https://neo4j.com/docs/operations-manual/current/tools/dump-load/
i used the above solution, but the file name was different.
in the folder of the neo4j data, look for folder called conf and inside the configuration file called neo4j.conf
inside this file you will see a line that direct to the folder that contain the data.
its called "graph.db"
replace it with the same folder from your backup of the DB that you want to clone.
