neo4j: Cypher LOAD CSV with uuid

由 旧街凉风 提交于 2019-12-05 17:53:46
I am starting to work with LOAD CSV of Cypher for Neo4J to import larger csv-files into my DB. I would like to add to each imported node a unique ID (uuid) as a property. My try was: LOAD CSV FROM "file:..." AS csvLine CREATE (c:Customer { uuid: {uuid}, name: csvLine[0], code: csvLine[1]}) Unfortunately I receive for each node the same UUID (although its a function that would normally generate the UUID new when called), it looks like the UUID is generated 1 time and then attached to each node while creating the node and parsing the csv-file. Is there a way to generate a new UUID for each

Neo4j Cypher - creating nodes and setting labels with LOAD CSV

由 不打扰是莪最后的温柔 提交于 2019-11-30 15:27:40
问题 I’m trying to use LOAD CSV to create nodes with the labels being set to values from the CSV. Is that possible? I’m trying something like: LOAD CSV WITH HEADERS FROM 'file:///testfile.csv' AS line CREATE (x:line.label) ...but I get an invalid syntax error. Is there any way to do this? 回答1: bicpence, First off, this is pretty easy to do with a Java batch import application, and they aren't hard to write. See this batch inserter example.
