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

Create a Neo4j database connection using the URLhttp://localhost:7474/db/data, user nameneo4j, and passwordmatlab.

url ='http://localhost:7474/db/data'; username ='neo4j'; password ='matlab'; neo4jconn = neo4j(url,username,password);

Check theMessageproperty of the Neo4j connection objectneo4jconn. The blankMessageproperty indicates a successful connection.

neo4jconn.Message

ans = []

Retrieve the first node in the table of node information. This node has the labelPerson.

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

Set theTitlenode 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 URLhttp://localhost:7474/db/data, user nameneo4j, and passwordmatlab.

url ='http://localhost:7474/db/data'; username ='neo4j'; password ='matlab'; neo4jconn = neo4j(url,username,password);

Check theMessageproperty of the Neo4j connection objectneo4jconn. The blankMessageproperty indicates a successful connection.

neo4jconn.Message

ans = []

Find nodes with the labelPerson.

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

Set theTitleandDepartmentnode 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. Thenodeinfooutput argument is aNeo4jNodeobject.

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.
