searchNodeByID

Search for Neo4j database node by node identifier

Syntax

nodeinfo = searchNodeByID(neo4jconn,nodeid)

Description

example

nodeinfo = searchNodeByID(neo4jconn,nodeid) creates the Neo4jNode object using the Neo4j® database connection neo4jconn and the node identifier nodeid.

Examples

collapse all

Create a Neo4j® database connection using the URL http://localhost:7474/db/data, user name neo4j, and password matlab.

url = 'http://localhost:7474/db/data';
username = 'neo4j';
password = 'matlab';

neo4jconn = neo4j(url,username,password);

Check the Message property of the Neo4j® connection object neo4jconn.

neo4jconn.Message
ans =

     []

The blank Message property indicates a successful connection.

Search the database for the node with node identifier 2 using the Neo4j® database connection neo4jconn.

nodeid = 2;

nodeinfo = searchNodeByID(neo4jconn,nodeid)
nodeinfo = 

  Neo4jNode with properties:

        NodeID: 2
      NodeData: [1×1 struct]
    NodeLabels: 'Person'

nodeinfo is a Neo4jNode object that contains these properties:

  • Node identifier

  • Node data

  • Node labels

Access the property keys and values of the node using the property NodeData.

nodeinfo.NodeData
ans = 

  struct with fields:

    name: 'User2'

Input Arguments

collapse all

Neo4j database connection, specified as a Neo4jConnect object created using the function neo4j.

Neo4j database node identifier, specified as a numeric scalar that denotes one specific node in the Neo4j database. If a node identifier is unknown, search for nodes using searchNode and relationships using searchRelation.

Data Types: double

Output Arguments

collapse all

Node information for one node in the Neo4j database, returned as a Neo4jNode object. You can use this node as the origin node for searching the Neo4j database.
