使用cypher的neo4j批量插入物
如何将以下内容插入neo4j使用cypher的neo4j批量插入物,neo4j,Neo4j,如何将以下内容插入neo4j create (st:serviceticket {name:'SRT_519'}) with st as st match (st:serviceticket) where st.name='SRT_519' match (d:ProductID) where d.name ='PRD_1014' with st as st , d as d merge (d)-[:SERVICE_TICKETID]->(st); create (st:serv
create (st:serviceticket {name:'SRT_519'})
with st as st
match (st:serviceticket) where st.name='SRT_519'
match (d:ProductID) where d.name ='PRD_1014'
with st as st , d as d
merge (d)-[:SERVICE_TICKETID]->(st);
create (st:serviceticket {name:'SRT_520'})
with st as st
match (st:serviceticket) where st.name='SRT_520'
match (d:ProductID) where d.name ='PRD_1004'
with st as st , d as d
merge (d)-[:SERVICE_TICKETID]->(st);
如果我要插入多个这样的记录,如何一次插入所有记录。请帮助我。我假设您的产品的节点已经存在 请记住,您的“st”是一个引用,您正试图在一批中分配同一引用两次。 第一步是为您的服务票提供单独的参考
match (d:ProductID), (e:ProductID)
where d.name ='PRD_1014'and
e.name ='PRD_1004'
create (st519:serviceticket {name:'SRT_519'})
create (st520:serviceticket {name:'SRT_520'})
merge (d)-[:SERVICE_TICKETID]->(st519)
merge (e)-[:SERVICE_TICKETID]->(st520)
如果使用参数,则可以提供一个对数组: 您应该对:ServiceTicket(名称)和:ProductID(名称)具有索引或约束
您的数据(SRT_519、PRD_1014)来自哪里?我已经创建了一个文件或另一个db或?PRD_1014节点,现在我需要将这些节点(如SRT_519)与
WITH [['SRT_519','PRD_1014']] as data
FOREACH (pair in data |
MERGE (st:ServiceTicket {name:data[0]}),(d:ProductID {name:data[1]})
MERGE (d)-[:SERVICE_TICKETID]->(st);
