How to push values to property array in Cypher?
arrays, cypher, neo4j
Solution
Adding values to an array is analogous to incrementing an integer or concatenating a string and is signified the same way, in your case (let `c` be your `[c:contains {id:[12345]}]`)
c.id = c.id + 1111 // [12345,1111]
c.id = c.id + 14567 // [12345,1111,14567]
or
c.id = c.id + [1111,14567] // [12345,1111,14567]
Problem
I have two nodes `user` and `files` with a relationship `:contains`, the relationship has a property `id`which is an array, represented as ``` (:user)-[:contains{id:[12345]}]->(:files) ``` However I want to populate the property array `id` with values `1111` and `14567` sequentially using `Cypher` queries, I dont find any method to push values into the array. After inserting 1111 to property `id` it will be: ``` (:user)-[:contains{id:[12345,1111]}]->(:files) ``` After inserting 14567 to property `id` it will be: ``` (:user)-[:contains{id:[12345,1111,14567]}]->(:files) ``` I don't know how to populate values to an property array sequentially.
