neo4j: What is the syntax to set cypher query parameters in the browser interface?

Question

I am trying to run queries from the neo4j browser to reproduce results from my neo4j-javascript-driver client.

What is the syntax for defining query parameters in the neo4j b

I recently attended a neo4j training session in NYC where the trainer (David Fauth) did this, unfortunately, I did not take notes on it, since I figured that I could read-up on this online...but no success.

Answer 1

In neo4j-browser you need type for example:

:params {nodes: [{name: "John", age: 18}, {name: "Phill", age: 23}]} 

Then you can use params as usual:

UNWIND {nodes} as node MERGE (A:User {name: node.name, age: node.age}) RETURN A 

For clear params in neo4j-browser type :params {}.

For additional help type :help params.

Answer 2

In Neo4j-3.3.4, the cypher likes this:

:param nodes: [{name: 'John', age: 18}, {name: 'Phill', age: 23}]
