Neo4j - Limit Clause
The limit clause is used to limit the number of rows in the output.
Syntax
Following is the syntax of the LIMIT clause.
MATCH (n)
RETURN n
ORDER BY n.name
LIMIT 3
Example
Before proceeding with the example, create 5 nodes in the Neo4j database as shown below.
CREATE(Dhawan:player{name:"shikar Dhawan", YOB: 1985, runs:363, country: "India"})
CREATE(Jonathan:player{name:"Jonathan Trott", YOB:1981, runs:229, country:"South Africa"})
CREATE(Sangakkara:player{name:"Kumar Sangakkara", YOB:1977, runs:222, country:"Srilanka"})
CREATE(Rohit:player{name:"Rohit Sharma", YOB: 1987, runs:177, country:"India"})
CREATE(Virat:player{name:"Virat Kohli", YOB: 1988, runs:176, country:"India"})
Following is a sample Cypher Query which returns the nodes created above in a descending order and limits the records in the result to 3.
MATCH (n)
RETURN n.name, n.runs
ORDER BY n.runs DESC
LIMIT 3
