Remove one node property from a single node in a Neo4j® database and access the node.

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. The blank Message property indicates a successful connection.

neo4jconn.Message

ans =

     []

Retrieve the first node in the table of node information. This node has the label Person.

nlabel = "Person";
nodeinfo = searchNode(neo4jconn,nlabel);
node = nodeinfo.NodeObject(1);

Set the Title node property for a single node in the database using the Neo4j database connection.

properties.Title = "Analyst";
setNodeProperty(neo4jconn,node,properties)

Display the node information for the updated node.

nodeinfo = searchNode(neo4jconn,nlabel);
node = nodeinfo.NodeObject(1);
node.NodeData

ans = struct with fields:
     name: 'User1'
    Title: 'Analyst'

Remove the node property.

propertyNames = "Title";
removeNodeProperty(neo4jconn,node,propertyNames)

Display the node information for the updated node.

nodeinfo = searchNode(neo4jconn,nlabel);
node = nodeinfo.NodeObject(1);
node.NodeData

ans = struct with fields:
    name: 'User1'

Close the database connection.

close(neo4jconn)

Remove node properties from multiple nodes in a Neo4j® database. Access the updated node information using an output argument.

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. The blank Message property indicates a successful connection.

neo4jconn.Message

ans =

     []

Find nodes with the label Person.

nlabel = "Person";
nodeinfo = searchNode(neo4jconn,nlabel);
nodes = nodeinfo.NodeObject;

Set the Title and Department node properties for multiple nodes using the Neo4j database connection. Display the updated node information for the first three nodes.

properties.Title = "Analyst";
properties.Department = "Sales";
nodeinfo = setNodeProperty(neo4jconn,nodes,properties);
nodeinfo.NodeData{1:3}

ans = struct with fields:
    Department: 'Sales'
          name: 'User1'
         Title: 'Analyst'

ans = struct with fields:
    Department: 'Sales'
          name: 'User3'
         Title: 'Analyst'

ans = struct with fields:
    Department: 'Sales'
          name: 'User2'
         Title: 'Analyst'

Remove the node properties using the property names. Display the updated node information for the first three nodes. The nodeinfo output argument is a Neo4jNode object.

propertyNames = ["Title" "Department"];
nodeinfo = removeNodeProperty(neo4jconn,nodes,propertyNames);
nodeinfo.NodeData{1:3}

ans = struct with fields:
    name: 'User1'

ans = struct with fields:
    name: 'User3'

ans = struct with fields:
    name: 'User2'

Close the database connection.

close(neo4jconn)
