Usage Examples
The examples in this section are based on the following graph:
CREATE (s:Student {name: 'Xavier', score: 82});
CREATE (s:Student {name: 'Jackson', score: 81});
CREATE (s:Student {name: 'Sophia', score: 74});
CREATE (s:Student {name: 'Ariana', score: 70});
CREATE (s:Student {name: 'Elena', score: 92});
CREATE (s:Student {name: 'Luca', score: 85});The apoc.create.vNodes is a procedure that takes a list or group of data and calls the procedure once for the entire batch.
We can use the same example from the apoc.create.vNode, but collect the scores into a single list for the procedure to create a node for each in a single call:
apoc.create.vNode Procedure
MATCH (s:Student)
WITH collect(s {.score}) as scores
CALL apoc.create.vNodes(['Score'],scores) YIELD node
RETURN node;| node |

{"score":81} |
{"score":74} |
{"score":70} |
{"score":92} |
{"score":85} |
