I co-authored the O'Reilly Graph Algorithms Book with Amy Hodler.

(rob)-[:DIRECTED]->(thePresident) (charlie)-[:ACTED_IN {role: 'Bud Fox'}]->(wallStreet), (michael:Person {name: 'Michael Douglas'}), (charlie)-[:ACTED_IN {role: 'Bud Fox'}]->(wallStreet), Since then the ages have been increasing as the tournament has been dominated by Djokovic and to a lesser extent Federer, both of whom are more than 30 years old now. (oliver:Person {name: 'Oliver Stone'}), (charlie)-[:ACTED_IN {role: 'Bud Fox'}]->(wallStreet), This could involve a scan of the database, a search for nodes having a certain label, or a search of an index to find starting points for the pattern … Cypher is Neo4j’s graph query language that allows users to store and retrieve data from the graph database. (rob:Person {name: 'Rob Reiner'}), (martin)-[:ACTED_IN {role: 'A.J. (wallStreet:Movie {title: 'Wall Street'}), (wallStreet:Movie {title: 'Wall Street'}), (martin:Person {name: 'Martin Sheen'}), (michael)-[:ACTED_IN {role: 'Gordon Gekko'}]->(wallStreet), (michael:Person {name: 'Michael Douglas'}), (wallStreet:Movie {title: 'Wall Street'}), (oliver)-[:DIRECTED]->(wallStreet), (oliver)-[:DIRECTED]->(wallStreet), (michael:Person {name: 'Michael Douglas'}), (thePresident:Movie {title: 'The American President'}), (martin:Person {name: 'Martin Sheen'}), CREATE (charlie:Person {name: 'Charlie Sheen'}), (martin:Person {name: 'Martin Sheen'}), (martin:Person {name: 'Martin Sheen'}), (wallStreet:Movie {title: 'Wall Street'}), CREATE (charlie:Person {name: 'Charlie Sheen'}), (rob:Person {name: 'Rob Reiner'}), (oliver)-[:DIRECTED]->(wallStreet), (oliver:Person {name: 'Oliver Stone'}), Here you can observe that the specified node is deleted. So the Cypher query above is querying nodes, their labels, and their properties.

Neo4j Newbie Questions. (michael)-[:ACTED_IN {role: 'President Andrew Shepherd'}]->(thePresident), (oliver:Person {name: 'Oliver Stone'}), (rob)-[:DIRECTED]->(thePresident) Neo4j will automatically work out the best approach to finding start nodes and matching patterns.

CREATE (charlie:Person {name: 'Charlie Sheen'}), It's generally recommended to limit the results to avoid unintended issues. (rob:Person {name: 'Rob Reiner'}), (martin)-[:ACTED_IN {role: 'A.J.
