问题描述

是否可以使用Cypher更改节点上的标签? 我有一个标签为Book的节点，如下所示.我想将Book标签更改为DeletedBook.

Is it possible to change a label on a node using Cypher? I have a node with label Book, as shown below. I want to change the Book label to DeletedBook.

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

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

推荐答案

您可以使用Book标签上的REMOVE和新标签上的SET来做到这一点:

You can do that using REMOVE on the Book label and SET on the new label:

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