[英]updating multiple properties in Cypher (neo4j)
I cannot update the node using SET for multiple properties in Neo4j, is there any way to handle this? 我无法使用SET来更新Neo4j中多个属性的节点,有什么方法可以处理吗?
start n=node:wordindex(word='repine') set n.wordType = 'rare' return n
If I want to add n.link = "..." how is that done? 如果我要添加n.link =“ ...”,该怎么做?
Here is the newest doc: http://neo4j.com/docs/developer-manual/current/cypher/clauses/set/ 这是最新的文档: http : //neo4j.com/docs/developer-manual/current/cypher/clauses/set/
MATCH (n { name: 'Peter' })
SET n += { hungry: TRUE , position: 'Entrepreneur' }
There are other ways also, so check the docs. 还有其他方法,因此请检查文档。
Also check this out if you are doing this from node.js : JSON.Stringify without quotes on properties? 如果您是通过node.js执行此操作的,还请检查一下: JSON.Stringify是否在属性上没有引号?
You can use util.inspect()
to get an object in like this: 您可以使用
util.inspect()
来获取对象,如下所示:
const util = require('util')
const params = {
hungry: TRUE ,
position: 'Entrepreneur'
}
const query = `
MATCH (n { name: 'Peter' })
SET n += ${util.inspect(params)}
RETURN n
`
start n=node:wordindex(word='repine')
set n.wordType = 'rare', n.link='link'
return n
should do it 应该做
