Introducing Cypher
Cypher is a declarative open query language that allows for expressive and efficient queries in a property graph. Originally built by Neo4j, Cypher is easy-to-learn and the widely adopted standard graph query language of developers worldwide.
MATCH
(j:Person
{name: "Adam"})-[r:LIKES]->
(tech:Technology)<-[r2:LIKES]-(p:Person)
WHERE tech.type IN ['Graphs', 'Development']
RETURN p.name;
Pattern Matching
Cypher works by matching patterns in your data using an ASCII-art style syntax.
ASCII-art Style Syntax
Draw nodes using parentheses. Simply define labels and properties as part of the pattern.
Traverse your Graph
Expand relationships by drawing using arrows, square brackets and an arrow to denote the direction.
Filter and Return
Filter data within the pattern or express more complex predicates in the WHERE clause and control the output using the RETURN clause.
