Neo4j – Order By Clause
You can arrange the result data in order using the ORDER BY clause.
Syntax
Following is the syntax of the ORDER BY clause.
MATCH (n) RETURN n.property1, n.property2 . . . . . . . . ORDER BY n.property
Example
Before proceeding with the example, create 5 nodes in 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 above created nodes in the order of the runs scored by the player using the ORDERBY clause.
MATCH (n) RETURN n.name, n.runs ORDER BY n.runs
To execute the above query, carry out the following steps −
Step 1 − Open the Neo4j desktop App and start the Neo4j Server. Open the built-in browser app of Neo4j using the URL http://localhost:7474/ as shown in the following screenshot.
Step 2 − Copy and paste the desired query in the dollar prompt and press the play button (to execute the query) highlighted in the following screenshot.
Result
On executing, you will get the following result.
Ordering Nodes by Multiple Properties
You can arrange the nodes based on multiple properties using ORDEYBY clause.
Syntax
Following is the syntax to arrange nodes by multiple properties using the ORDERBY clause.
MATCH (n) RETURN n ORDER BY n.age, n.name
Example
Following is a sample Cypher Query which arranges the nodes created earlier in this chapter based on the properties – runs and country.
MATCH (n) RETURN n.name, n.runs, n.country ORDER BY n.runs, n.country
To execute the above query, carry out the following steps −
Step 1 − Open the Neo4j desktop App and start the Neo4j Server. Open the built-in browser app of Neo4j using the URL http://localhost:7474/ as shown in the following screenshot.
Step 2 − Copy and paste the desired query in the dollar prompt and press the play button (to execute the query) highlighted in the following screenshot.
Result
On executing, you will get the following result.
Ordering Nodes by Descending Order
You can arrange the nodes in a database in a descending order using the ORDERBY clause.
Syntax
Following is the syntax to arrange the nodes in a database.
MATCH (n) RETURN n ORDER BY n.name DESC
Example
Following is a sample Cypher Query which arranges the nodes in a database in a descending order using the ORDERBY clause.
MATCH (n) RETURN n.name, n.runs ORDER BY n.runs DESC
To execute the above query, carry out the following steps −
Step 1 − Open the Neo4j desktop App and start the Neo4j Server. Open the built-in browser app of Neo4j using the URL http://localhost:7474/ as shown in the following screenshot.
