使用 Load csv 未添加 Neo4j 关系

Question

我正在尝试使用neo4j 的Load csv 方法。我已成功将所有节点添加到 neo4j。但是当涉及到 relationships 时，密码语句运行没有任何错误，但它们永远不会被添加并且在浏览器中不可见。但是可以看到节点就好了。以下是我的 CSV。

第一个是 Customer.csv 第二个是 customer_send.csv

         Galactic_ID:ID(Customer),:LABEL
 1000000000036666531,Customer
 2000000000198737143,Customer

以下是我的密码语句：

In [24]: stmt6 = """USING PERIODIC COMMIT LOAD CSV FROM "file:///mnt/database/Neo/db3/import_data1/customer.csv" AS csvLine
 ....: MERGE (c:Customer {Galactic_ID:csvLine[0]})
 ....: ON CREATE SET c.Galactic_ID = csvLine[0]"""

    stmt3 = """USING PERIODIC COMMIT LOAD CSV     FROM"file:///mnt/database/Neo/db3/import_data1/customer_send.csv" AS csvLine
 Match (a:Customer {Customer:csvLine[0]}), (c:Customer {Customer:csvLine[1]})
 Merge (a)-[r:Customer_Send]->(c)
 On Create SET r.TXN_KEY = csvLine[2], r.Amount = csvLine[3], r.SendTime = csvLine[4], r.PayTime = csvLine[5]"""


graph.cypher.execute(stmt6)

graph.cypher.execute(stmt3)

创建客户节点的第一个图形 stmt 运行很好，节点已创建并在图形中可见。第二个 stmt 运行s 一段时间后结束，没有任何错误，但没有创建关系。

Answer 1

尝试匹配属性上您创建它们的节点：

Match (a:Customer {Customer:csvLine[0]}), (c:Customer {Customer:csvLine[1]})

=>

Match (a:Customer {Galactic_ID:csvLine[0]}), (c:Customer {Galactic_ID:csvLine[1]})
