CREATE GRAPH

Create a subgraph

Subgraphs provide isolation and configuration separate from the rest of the system, similar to CREATE DATABASE and USE DATABASE in relational databases. Each subgraph has its own schema, data, and configuration.

Strictly typed subgraphs (default)

By default, all subgraphs are strictly typed, meaning you must create node and relationship tables before inserting data.

CREATE GRAPH my_graph;
USE my_graph;
CREATE NODE TABLE User(name STRING PRIMARY KEY);
CREATE (u:User {name: 'Alice'});

Open type graphs

Open type graphs allow you to create nodes with labels without first defining the node table. This provides compatibility for users migrating from GQL or Neo4j.

CREATE GRAPH my_graph ANY;
USE my_graph;
CREATE (u:User {name: 'Alice'});

In open type graphs, you can still use CREATE NODE TABLE if you want to define a strict schema.

Switch between subgraphs

Use USE to switch between subgraphs:

USE my_graph;

To list all available subgraphs:

CALL SHOW_GRAPHS() RETURN *;

Drop a subgraph

To drop a subgraph and all its contents:

DROP GRAPH my_graph;
