Question

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 impor

Answer 1

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

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

If you want to include double quotes, you can wrap in single quotes:

CREATE (n:Node {name:'hello " world'}) 
RETURN n.name

n.name
hello " world

If you want to include single quotes, you can wrap in double quotes:

CREATE (n:Node {name:"hello ' world"}) 
RETURN n.name

n.name
hello ' world

If it's more complicated than that, you can escape the character:

CREATE (n:Node {name:"hello \" world"}) 
RETURN n.name

n.name
hello " world

You can also include backslashes by escaping them:

CREATE (n:Node {name:"hello \\ world"}) 
RETURN n.name

n.name
hello \ world
