Join William Lyon for an in-depth discussion in this video Read operations in Neo4j, part of Database Clinic: Neo4J.
- [Instructor] The final CRUD operation…that we'll complete is the read task.…We'll need to read each line from the database…and print it out to the console.…So, let's first define a query…to read each line from the database.…This is going to be a match statement.…We need to specify the graph pattern…that we want to match on.…In this case, it's just a line node.…We don't need to specify a predicate or a where clause,…because we need to match on every line…and simply return the text property,…which we'll alias to text, and the line number,…which we'll alias to linenum.…
Let's execute that cell to bring that into scope,…and now what we want to do is create a session object…to connect to Neo4j.…We'll grab the beginning time stamp, and we need to read…each line from the database, so we will call session.run,…passing in our read_lines_query.…Result is an iterator, so we need to iterate…over each record in the result, printing out each line.…
We will reference the line number and text values…from the record object, using this subscript notation.…
