apoc.node.id
Function APOC Core
returns id for (virtual) nodes
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;| 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 |
