neo4j图数据库，如何更新一个节点或一个关系的信息？

match(n:Person) set n:Human

match(n:Human) set n:人类 remove n:Human

match(n:Person) remove n:人类

Match(n:Person{name:'sunan'}) set n.name='sunan',n.born=2000,n.live='北京'

Match(n:Person{name:'sunan'}) remove n.born return n

Match(n:Person{name:'sunan'}) set n.生活在=n.live remove n.live return n

MATCH (a),(b) WHERE a.name="sunan" AND b.title="The Matrix" CREATE (a) -[r:Watch {count: 1}]-> (b) return r;
match (n:Person{name:'sunan'})-[r]->(m:Movie{title:'The Matrix'}) return type(r);

match (n:Person{name:'sunan'})-[r]->(m:Movie{title:'The Matrix'}) set r.aa="aaa" return r,type(r)

match (n:Person{name:'sunan'})-[r]->(m:Movie{title:'The Matrix'})
remove r.aa
return r,type(r)

MATCH (n:Person{name:'sunan'})-[r:Watch]->(m:Movie{title:'The Matrix'})
CREATE (n)-[r2:Learn]->(m)
SET r2 = r
WITH r
DELETE r
