Neo4j如何处理Cypher语句中的特殊字符，如"\" [英] Neo4j how to handle special characters like ” \ in Cypher statements

问题描述

我正在使用py2neo将JSON数据作为chyper语句加载到Neo4j中. 我的问题是，有时我想作为属性导入到节点的字符串中有 ‘ \等符号:

I am using py2neo to load JSON data into Neo4j as chyper statements. My problem is that sometimes there are signs as " ‘ \ etc in the strings I want to import as properties to Nodes:

MERGE (p:Node {name:’This sign ‘ gives error’})

如果我更改为:

MERGE (p:Node {name: This sign ‘ gives error})

它将对语句结束有效，但是当在输入字符串中时将失败.

It will work for the statement over but it will fail when a " is in an input string.

有没有办法说字符串中允许所有(或几乎所有)特殊字符? 抱歉，这是一个愚蠢的问题:)

Is there a way to say that all (or almost all) special character is allowed inside the string? Sorry if this is a stupid question :)

推荐答案

我建议使用参数，然后密码解析器看不到它们.

I would suggest to use parameters, then the cypher parser doesn't see them.

这只是一个名称->您通过字典传递给execute方法的字符串.

And it's just an name -> string you pass via a dictionary to the execute method.
