Creating a node

The simplest instruction to create a node is the following:

CREATE ()

It creates a node, without a label or a relationship.

We can recognize the () pattern that is used to identify nodes within Cypher. Every time you want a node, you will have to use brackets.

We can check the content of the database after this statement with a simple MATCH query that will return all nodes of the graph:

MATCH (n)
RETURN n

Here, we are selecting nodes (because of the use of () ), and we are also giving a name, an alias, to these nodes: n. Thanks to this alias, we can refer to those nodes in later parts of the query, here only in the RETURN statement.

The result of this query is shown here:

OK, great. But a single node with no label nor properties is not sufficient for most use cases. If we want to assign a label to a node when creating it, here is the syntax to use:

CREATE (:Label)

That's already better! Now, let's create properties when creating the node:

CREATE (:Label  {property1...
