When you want to return all nodes, relationships and paths found in a query, you can use the * symbol. This returns the two nodes, the relationship and the path used in the query.
Deleting Nodes and Relationships Deleting all nodes and relationships in a Neo4j database is very simple. Here is an example that does just that: MATCH (n) DETACH DELETE n; The DETACH keyword specifies to remove or “detach” all relationships from a particular node before deletion.
Neo4j Browser is the easiest way to access a Neo4j database. To establish a connection, you enter the DBMS URL, the name of the database you want to connect, and the user credentials. You can also use the :server command to manage the connection to Neo4j.
Labels are used when defining constraints and adding indexes for properties (see Schema). An example would be a label named User that you label all your nodes representing users with. With that in place, you can ask Neo4j to perform operations only on your user nodes, such as finding all users with a given name.
You may also want to try a cypher query such as:
START n=node(*) RETURN n; It's very obvious, and it will return all the existing nodes in the database.
EDIT : the following displays the nodes and the relationships :
START n=node(*) MATCH (n)-[r]->(m) RETURN n,r,m; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
