Join William Lyon for an in-depth discussion in this video Import data, part of Database Clinic: Neo4J.
- [Instructor] Now there's several tools that we can use…to import data in Neo4j, but for this task…we'll make use of LOAD CSV.…LOAD CSV is a functionality built into Cypher…that allows us to stream the results of a CSV file…as an object to the rest of our Cypher statement…so we can use the same ASCII art style graph patterns…to create data, iterating over each row in the CSV file.…Let's see how this works.…So if we're inspecting our CSV file previously,…we saw that it had headers,…so we'll use the WITH HEADERS statement here,…and I copied the name of the CSV file earlier…when we moved it.…
Notice here that we specify the CSV file…just at the root level.…By default, Neo4j assumes this is relative…to the import directory that we created…within the Neo4j database directory.…So we specify the location for our CSV file,…and then we need to create an alias or a variable…to refer to the object that represents each row…of the CSV file that we iterate over.…In this case, we'll call it row.…
Now, let's just return the first five rows…
