Neo4j - Node Label

This example Application demonstrates how to read node data corresponding to a node label from a Neo4j instance using this Connector. In this case, movies released after 2000.

You can download the files here to try it out for yourself - adjusting the steps to use your own Neo4j credentials.

Refer to configuration to understand all configuration options of this Connector.

Step 1: Add the Connection

From the Properties blade of the widget to which the Neo4j Connector will be linked, a data grid in our example, select the Data Source tab.

Click the plus icon next to Data Source and then the plus icon next to Connection.

Node Example Step 1a: Add the Connection

Select the Neo4j Connector and enter a name for the connection. In this case, set the name to "Movies".

Node Example Step 1b: Select Connector and Name the Connection

Step 2: Configure Server and Database

Enter the Server details: the URI, User Name, and Password. In this case, tick to use variables.

Select the Database, tick to specify a cypher, paste the Cypher Query, and select a Primary Key.

In this case:

• Database: neo4j

• Cypher: MATCH (movie:Movie)-[ActedIn]-(person:Person) RETURN movie.title AS movie, person.name AS Actor, person.born AS Born, movie.released AS Released

• Primary Key: movie

Click Save.
