Join William Lyon for an in-depth discussion in this video Import data for calculations, part of Database Clinic: Neo4J.
- [Instructor] We've refactored the data model to include…a year node, now we're ready to import…the educational attainment data.…Let's first inspect our data by using Load CSV…with headers to parse and display…the first five rows.…I copied the name of our CSV file earlier,…so I just pasted that in.…Let's return row limit five…to show us the first five rows.…So, we're now parsing the CSV file that we downloaded…from the California open data portal and saved in the import…directory within the neo4j database directory.…
And we get back these objects, one for each row…in the CSV file.…And we can see, as we mentioned earlier,…that year is stored, actually, as a date string.…We need to extract out the year component of this date…to be able to match the year property, in this case,…2008 for this observation, to our year nodes.…Now, the Apoc procedure library that we just added…has functionality for working with dates…including the ability to parse a date string…and extract out individual date components, or fields.…
