neo4j：Cypher用uuid加载CSV [英] neo4j: Cypher LOAD CSV with uuid

问题描述

我开始使用Cypher的LOAD CSV来为Neo4J导入较大的csv文件到我的数据库。我想为每个导入的节点添加一个唯一ID（uuid）作为属性。

我的尝试是：

  LOAD CSV FROMfile：...AS csvLine 
 CREATE（c：Customer {uuid：{uuid}，name：csvLine [0]，code：csvLine不幸的是，我收到每个节点相同的UUID（虽然它的一个函数，它将是一个函数）通常在调用时生成UUID新），它看起来像UUID生成1次，然后附加到每个节点，同时创建节点并解析csv文件。
 
 
 
是否有一种方法为每个导入的csv行生成新的UUID以标记节点？

不知道你在哪里看到{uuid}是一个函数。 
它只是使用你传递的参数作为参数uuid。
 
 
 
在创建CSV时，你必须生成一个uuid。 
在cypher中目前没有 uuid（）函数。
 
 
 
 ：
  LOAD CSV FROMfile：...AS csvLine 
 CREATE（c：Customer {name：csvLine [0]，code：csvLine [1]}）
 SET c.id = id（c）
  
 
I am starting to work with LOAD CSV of Cypher for Neo4J to import larger csv-files into my DB. I would like to add to each imported node a unique ID (uuid) as a property.

My try was:
LOAD CSV FROM "file:..." AS csvLine
CREATE (c:Customer { uuid: {uuid}, name: csvLine[0], code: csvLine[1]})
Unfortunately I receive for each node the same UUID (although its a function that would normally generate the UUID new when called), it looks like the UUID is generated 1 time and then attached to each node while creating the node and parsing the csv-file.

Is there a way to generate a new UUID for each imported csv-line to mark the node?

Thanks for your hints from

Not sure where you've seen that {uuid} is a function. 
It is just using whatever you pass in as an parameter "uuid".

You'd have to generate a uuid when creating your CSV. 
In cypher there is currently no uuid() function.

One workaround that you could do is:
LOAD CSV FROM "file:..." AS csvLine
CREATE (c:Customer { name: csvLine[0], code: csvLine[1]})
SET c.id = id(c)
