Cypher语句学习

1. 根据一个节点的name来查询这个节点及其周边关系

MATCH p=(:Disease {name:'Cancer'})-[]->() RETURN p 

2.根据关系查询与这些关系有关的节点

MATCH p=()-[r:hasTreatment|hasFrequence]->() RETURN p

3.根据节点标签和name进行精准删除

match (m: Population) where m.name = 'Weight' DETACH delete m 

4.根据多个条件复合查询

MATCH p=(:Occupation {name:'	Music conductor and actor	'})-[]->(), n=()-[r:hasTreatment|hasFrequence]->()  RETURN p,n

5.删除所有节点和关系

match (n) detach delete n
