问题描述
是否可以将地图添加为属性?我想将地址行1、2等存储在address属性本身内.
Is there a way to add a map as property? I want to store address line 1, 2 etc inside the address property itself.
类似的东西-
RETURN {address: {firstline:"a", secondline:"b"}, name:"ABC"}
但是，当我在CREATE或SET中尝试此操作时，会给我错误.
However when I try this in CREATE or SET it gives me error.
我尝试过-
create (a:Person {name: "ABC", address: {firstline:"a", secondline:"b"}})
错误-
Property values can only be of primitive types or arrays thereof
推荐答案
可以将地图添加为属性.您应该将Address创建为单独的节点，然后使用Person创建relationship.或将地址作为property array添加到Person，例如
It is not possible to add map as a property. You should either create Address as a separate node and create a relationship with the Person. Or add the address as a property array to the Person, eg.,
(a:Person {name: "ABC", address: ["a", "b"]})
当然，您稍后将不得不将该数组转换回应用程序中的某个位置，以获取您最初想要的地图.
Of course, you would later have to convert that array back somewhere in your application to get the map you originally wanted.
