How to change / update a shortcut in Neo4j - Cypher?

Question

Is it possible to change the label to node using Cypher? I have a node with a label Bookas shown below. I want to change the label Bookto DeletedBook.

(u:Person)-[r]-(b:Book{id:id1})

(u:Person)-[r]-(b:DeletedBook{id:id1})

Answer 1

You can do this using REMOVEon the shortcut Bookand SETon the new shortcut:

MATCH (p:Person)-[r]-(b:Book {id: id1})
REMOVE b:Book
SET b:DeletedBook
RETURN b

You should check out the Neo4j Cypher Refcard for a full reference to Cypher 2.x.

Answer 2

You can use "REMOVE" to delete and SET to add a new label.

eg:

MATCH (p:Person)-[r]-(b:Book {id: id1})
REMOVE b:Book
SET b:DeletedBook
RETURN b

"" , . .

MATCH (p:Person)-[r]-(b:Book {id: id1})
SET b: Deleted
RETURN b
