Your challenge is to modify this Cypher query to add the languages property.
cypher
LOAD CSV WITH HEADERS
FROM 'https://data.neo4j.com/importing-cypher/movies.csv'
AS row
MERGE (m:Movie {movieId: toInteger(row.movieId)})
SET
m.tmdbId = toInteger(row.tmdbId),
m.imdbId = toInteger(row.imdbId),
m.released = date(row.released),
m.title = row.title,
m.year = toInteger(row.year),
m.plot = row.plot,
m.budget = toInteger(row.budget),
m.imdbRating = toFloat(row.imdbRating),
m.poster = row.poster,
m.runtime = toInteger(row.runtime),
m.imdbVotes = toInteger(row.imdbVotes),
m.revenue = toInteger(row.revenue),
m.url = row.url,
m.countries = split(row.countries, '|')The languages property should be the list of languages in the CSV file. As with countries each language is separated by the (|) character.
Validate countries and languages
Once you had imported the countries and languages properties as lists, click the Check Database button to verify that the task is complete.
Hint
Modify the Movie import Cypher to set the countries and languages properties as lists using split().
Solution
Run this Cypher statement to update the Movie properties to use the correct data type.

m.languages = split(row.languages, '|')Summary
In this lesson, you learned about multi-value properties, lists and how to create them using the split function.
In the next lesson, you will learn how to set multiple labels on nodes.
