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

我最近在纽约参加了neo4j培训课程，培训师(David Fauth)做到了这一点，很遗憾，我没有做笔记，因为我认为自己可以在网上阅读这本书...但是没有成功

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.

推荐答案

在neo4j浏览器中，您需要输入以下示例:

In neo4j-browser you need type for example:

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

然后您可以照常使用参数:

Then you can use params as usual:

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

要获取neo4j浏览器中清晰的参数，请键入:params {}.

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

有关其他帮助，请键入:help params.

For additional help type :help params.
