apoc.node.id

Details
Syntax	`apoc.node.id(node)`
Description	Returns the id for the given virtual `NODE`.
Arguments	Name	Type	Description
	`node`	`NODE`	The node to return the id from.
Returns	`INTEGER`

Usage Examples

The examples in this section are based on the following graph:

CREATE (s:Student {name: 'Alice', score: 71});
CREATE (s:Student {name: 'Mark', score: 95});
CREATE (s:Student {name: 'Andrea', score: 86});
CREATE (s:Student {name: 'Rajesh', score: 89});
CREATE (s:Student {name: 'Jennifer', score: 96});
CREATE (s:Student {name: 'Katarina', score: 80});

If we create virtual nodes containing students scores, we can use apoc.node.id to return the node id of those virtual nodes:

apoc.create.vNode Procedure

MATCH (s:Student)
CALL apoc.create.vNode(['Score'],{value: s.score})
YIELD node
RETURN node, apoc.node.id(node) AS nodeId;

Results
node	nodeId
(:Score {value: 71})	-13
(:Score {value: 95})	-14
(:Score {value: 86})	-15
(:Score {value: 89})	-16
(:Score {value: 96})	-17
(:Score {value: 80})	-18
