台湾林奕含@Query注解写neo4j语句的操作根据某值更新关系属性
match ()-[r:logicRelation]->()
where r.logicDevRelationId={logicDevRelationId}
t r.name = {name},r.fromPort = {fromPort},r.toPort = {toPort},r.status={status},r.type= {type} return r烹饪技法
深度为3的查询
match data=(na:logic{logicDevId:{logicId}})-[*1..3]->(nb:logic) return data
通过条件的匹配查询
MATCH data=(n:physics)-[r]->() pe={type} and nId={netId} RETURN data
桌球图片通过某值来删除/查询/更新节点
match(n:physics) where n.physicsDevId={physicsDevId} delete n return n
match(n:physics) where n.physicsDevId={physicsDevId} return n
MATCH (n {physicsDevId:{physicsDevId}})
牧童骑
SET n.name={name}, n.status={status} ,n.type={type},nId={netId} RETURN n
根据两节点id，关系id删除/更新指定关系
MATCH p=(:physics{physicsDevId:{physicsSrcId}})
-[r:physicsDevRelation{physicsDevRelationId:{physicsDevRelationId}}]->
素质拓展训练心得体会
(:physics{physicsDevId:{physicsDesId}}) delete r抗日名将左权
MATCH p=(:physics{physicsDevId:{physicsSrcId}})
抗战之铁血佣兵-[r:physicsDevRelation{physicsDevRelationId:{physicsDevRelationId}}]->
(:physics{physicsDevId:{physicsDesId}})
SET r.name = {name},r.fromPort = {fromPort},r.toPort = {toPort},r.status={status},r.type= {type}
当然springboot集成的neo4j⾃带的语句更⽅便，写下是为了提醒⾃⼰得语法记忆青春期女生怎么丰胸
