我正在尝试使用JavaScript设置(更新)Neo4j.我正在使用JavaScript语言驱动程序.

I'm trying to SET (update) a Neo4j using JavaScript. I'm using the JavaScript language drivers.

我的代码执行了，但是节点属性没有更新.

My code executes but the node properties do not update.

这是我的代码:

return session.run("MATCH (a:Person) WHERE a.ID = {id} SET a.name = {name}, a.email = {email}", { id: 114, name: name, email: email });

推荐答案

JavaScript数字是32位，Neo4j是64位，在设置或检索数字数据时需要执行一些转换.

Javascript numbers are 32 bit, Neo4j's are 64 bit, there's some conversion you'll need to perform when setting or retrieving numeric data.

在驱动程序自述文件中，这是相关部分.传递的数字将转换为浮点数，因此您需要通过neo4j.int()传递数字以将其强制为int类型，如下所示:

Here's the relevant section on this in the driver readme. The number being passed gets converted into a float, so you need to pass the number through neo4j.int() to force it to an int type like so:

return session.run("MATCH (a:Person) WHERE a.ID = {id} SET a.name = {name}, a.email = {email}", { id: neo4j.int(114), name: name, email: email });
