问题描述

我找不到在Cypher中更改关系类型的方法.完全可以执行此操作吗?如果没有:实现此结果的最佳方法是什么?

I can't find a way to change a relationship type in Cypher. Is this operation possible at all? If not: what's the best way achieve this result?

推荐答案

不幸的是，目前无法直接更改rel类型.

Unfortunately there is no direct change of rel-type possible at the moment.

您可以这样做:

MATCH (n:User {name:"foo"})-[r:REL]->(m:User {name:"bar"})
CREATE (n)-[r2:NEWREL]->(m)
// copy properties, if necessary
SET r2 = r
WITH r
DELETE r
