Overview: Neo4j JDBC Driver

This is the official JDBC driver for Neo4j.

This driver was mainly developed by Larus BA, Italy, a certified consulting and integration solutions partner for Neo4j. Thank you so much for all your work.

The previous JDBC driver for Neo4j 2.x was moved to the https://github.com/neo4j-contrib/neo4j-jdbc-2x repository.

Being a graph database, Neo4j is not serving data in a relational way and the exact purpose of this project is to allow projects that are using the classic JDBC connector in the relational paradigm to interact with Neo4j.

This driver supports various types of database transports:

  • through the Bolt protocol (3.1.x and 3.0.x) using jdbc:neo4j:bolt://<host>:<port>/

  • through the HTTP protocol (2.x+) using jdbc:neo4j:http://<host>:<port>/

Going forward there will also be support for:

  • direct file connection

  • embedded connection

Maven dependency

For the all-in-one module supporting both Bolt and HTTP, you can simply use:


If you only want one of the protocols, you can depend on its module:




Minimum viable snippet

Dependency declaration
Run Query
// Connecting
try (Connection con = DriverManager.getConnection("jdbc:neo4j:bolt://localhost", 'neo4j', password)) {

    // Querying
    String query = "MATCH (u:User)-[:FRIEND]-(f:User) WHERE u.name = {1} RETURN f.name, f.age";
    try (PreparedStatement stmt = con.prepareStatement(query)) {

        try (ResultSet rs = stmt.execute()) {
            while (rs.next()) {
                System.out.println("Friend: "+rs.getString("f.name")+" is "+rs.getInt("f.age"));

Please note that the example above uses the try-with-resource blocks that automatically closes resources when the try block is exited.

Usage with Neo4j Server

  • Install a Neo4j 3.1.x server and start it with the Bolt protocol enabled

  • Connect with URLs in the form jdbc:neo4j:bolt://<host>:<port>/ (e.g. jdbc:neo4j:bolt://localhost/)

  • You can also use additional comma separated parameters in the URL for authentication, debug mode, SSL encryption and flattening e.g. jdbc:neo4j:bolt://localhost/?user=neo4j,password=xxxx,debug=true,noSsl,flatten=[-1,100,1000]

  • Add the JDBC driver dependency or jar file to your project

  • Get a connection from DriverManager

  • Execute queries and transactions using the Cypher graph query language


As most JDBC clients and tools don’t support complex objects, the driver can flatten returned nodes and relationships by providing all their properties as individual columns with names like u.name,r.since if you just return a node u or relationship r.

This is enabled with the JDBC-URL parameter flatten=<rows>, where <rows> indicates how many rows are sampled to determine those columns. With -1 all rows are sampled and with any other value you determine the number of rows being looked at.

Building the driver yourself

First clone the repository.

This project is composed by the following modules:

Run all unit tests & integration tests
mvn clean test
Run only integration tests
mvn clean test -Pintegration-test
Run performance tests
mvn clean test -Pperformance-test
To run the performance test, you must have a Neo4j Server 3.1.x running with the Bolt protocol enabled on port 7687 (default)

Technical Reference

Usage Examples

The Bolt Driver

The Bolt driver connects to any Neo4j 3.x database that has the binary "Bolt" transport enabled.

It uses the neo4j-java-driver to provide the connectivity.

Just provide your username and password and you can connect to Neo4j.

The JDBC URL has this format: jdbc:neo4j:bolt://host:port/?username=neo4j,password=xxxx

The HTTP Driver

The HTTP driver uses the existing (since Neo4j 2.x) transaction Cypher HTTP API, and is implemented using Apache Commons httpclient and Jackson for JSON (de)serialization.

The JDBC URL has this format: jdbc:neo4j:http://host:port/?username=neo4j,password=xxxx

JDBC Compatibility

We cover these aspects of the JDBC-APIs, everything that’s not explicitely mentioned should be assumed to be not implemented:

  • Driver handling automatic loading and JDBC URLs

  • Connection, incl. autocommit and manual commit

  • Transactions

  • Statements for reads and writes

  • PreparedStatement for reads and writes, including parameters, both question marks ? and named numbered parameters {1}

  • ResultSet retrieving all columns as String, Object and their native type with optional conversions

Libraries and Frameworks

Java JDBC Usage

Plain JDBC usage was already shown before:

Dependency declaration
Run Query
// Connecting
try (Connection con = DriverManager.getConnection("jdbc:neo4j:bolt://localhost", 'neo4j', password)) {

    // Querying
    String query = "MATCH (u:User)-[:FRIEND]-(f:User) WHERE u.name = {1} RETURN f.name, f.age";
    try (PreparedStatement stmt = con.prepareStatement(query)) {

        try (ResultSet rs = stmt.execute()) {
            while (rs.next()) {
                System.out.println("Friend: "+rs.getString("f.name")+" is "+rs.getInt("f.age"));

Spring JDBC Template

Integrating with Spring JDBC is as easy as defining a datasource in your Spring config and then using it via JDBC Template.

You can find an example application here:

Play Framework

Taken from the Play Framework Documentation. Enable the database plugin by adding javaJdbc in your build dependencies:

libraryDependencies += javaJdbc

Then you must configure a connection pool in the conf/application.conf file. By convention the default JDBC data source must be called default, but you can use other names for named databases, in this case we use neo4j

# Neo4j database configuration
import javax.inject.Inject;

import play.mvc.Controller;
import play.db.NamedDatabase;
import play.db.Database;

// inject "neo4j" database instead of "default"
class JavaNamedDatabase extends Controller {
    private Database db;

    public JavaNamedDatabase(@NamedDatabase("neo4j") Database db) {
        this.db = db;

    // do whatever you need with the db

QlikView / Qlik Sense via TIQ JDBC Connector

(Thanks a lot to Ralf Becher, TIQ Solutions)

TIQ Solutions provides a commercial product to enable JDBC connectivity in QlikView and Qlik Sense. The configuration is simple.

In QlikView, you can connect to Neo4j directly. In Qlik Sense you need to copy the CUSTOM CONNECT script code.

d04d482a 54d3 11e6 8813 29d3d701ea2b

If your Neo4j connection is established, you now can execute Cypher queries in LOAD statements (but mention the SQL prefix). The results get loaded into memory tables as usual.

Tableau via jdbc2tde

(Thanks a lot to Ralf Becher, TIQ Solutions)

Integration with Tableau is not that trivial as it only generates SQL.

So you can either use the Tableau REST integration (which we will publish soon).

ba8d8f42 54d6 11e6 9838 d0e7104d36ab

Or the jdbc2tde tool from TIQ that uses JDBC queries to generate TDE files.

Those can then be loaded into Tableau and visualized and interacted with in the many ways you know and love.

  • If all ok, you should have like this:

813e5e2a 34e6 11e6 81cf 5492c664c041


(Thanks a lot to Benoit Simard)

With Talend, you can query or import your data into Neo4j using Talend JDBC Components. On the Job, you just have to add a tJDBCConnection and add the usual fields: JDBC-URL, Driver-Jar, Driver, username and password.


NB: On the Advanced Settings tab, you can also configure the auto-commit, if you want it.

Now, you can add some tJDBCInput to make some queries to your Neo4j databases like this :


Database Tools

Squirrel SQL

Squirrel SQL is a widely used SQL workbench that supports many databases out of the box. Adding the JDBC driver was straightforward, as was running Cypher queries and getting tabular results back.

Works in general for scalar values

  • Configured Driver via Add Driver → Extra ClassPath

  • Created New Session,

  • Worked but gave a warning about 2.1 incompatibility

Apache SolR


You can index your Neo4j database directly into SolR with the help of SolR Data Import Handler (DIH) feature and the neo4j jdbc driver. This article is just on how to make the glue the two component via the JDBC driver.


Download the lastest release of SolR (for example : http://apache.crihan.fr/dist/lucene/solr/6.1.0/solr-6.1.0.tgz)

$>cd /tmp
$> wget http://apache.crihan.fr/dist/lucene/solr/6.1.0/solr-6.1.0.tgz

Extract it to a folder (reference as SOLR_HOME)

$> tar xzvf solr-6.1.0.tgz -C SOLR_HOME

Copy the folder SOLR_HOME/example/example-DIH/solr/solr to SOLR_HOME/server/solr/neo4j. This will create a new SolR core called neo4j with all DIH feautres enabled.

$> cp -rf SOLR_HOME/example/example-DIH/solr/solr SOLR_HOME/server/solr/neo4j

Copy The Neo4j JDBC Driver jar into folder SOLR_HOME/server/solr/neo4j/lib (create the folder of it doesn’t exist).

$> mkdir SOLR_HOME/server/solr/neo4j/lib
$> cp neo4j-jdbc-driver-3.0.1-SNAPSHOT.jar SOLR_HOME/solr/server/solr/neo4j/lib/

Edit the file SOLR_HOME/server/solr/neo4j/config/solrconfig.xml to add lib folder by adding this line :

<lib dir="./lib" />

We will configure SolR DIH feature by editing the file SOLR_HOME/server/solr/neo4j/config/solr-data-config.xml. Just replace its content by this one (don’t forget to replace the jdbc url, login password by yours):


	<dataSource type="JdbcDataSource"
				password="test" />

	<document name="movie">
        <entity name="movie" query="MATCH (m:Movie) RETURN id(m) AS id, m.title AS title, m.tagline AS tagline, m.released AS released">
             <field name="id" column="id" />
	         <field name="title" column="title" />
             <field name="tagline_s" column="tagline" />
             <field name="release_i" column="released" />


Start SolR server :

$> SOLR_HOME/bin/solr start

Open your browser at this url, http://localhost:8983/solr/#/neo4j/dataimport//dataimport , and click on the Execute button. A click on the refresh status allow you to see the status of the indexation.

solr dih
