Set labels using Cypher

Labels can be referenced dynamically in Cypher without using APOC.

Cypher syntax for setting a label dynamically

SET n:$(label)

The dynamically calculated label must evaluate to a STRING or LIST<STRING>. For more information, see the Cypher Manual → Dynamically setting a label.

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

CREATE (:Movie {title: 'A Few Good Men', genre: 'Drama'});

We can move the 'genre' property to a label, remove it as a property, and delete any other labels using both APOC and Cypher

apoc.create.setLabels

MATCH (n:Movie)
CALL apoc.create.setLabels( n, [ n.genre ] )
YIELD node
REMOVE node.genre
RETURN node;

Using Cypher’s dynamic labels

MATCH (n:Movie)
REMOVE n:$(labels(n))
SET n:$(n.genre)
REMOVE n.genre
RETURN n

Results
node
(:Drama {title: "A Few Good Men"})

If we want to only add new labels and not remove existing ones, see apoc.create.addLabels
