Parse.com query objects where the key's array value contains any of the elements

Question

on https://parse.com/docs/js_guide#queries-arrays there is an example how to find objects where the key's array value contains each of the elements 2, 3, and 4 with the following:

// Find objects where the array in arrayKey contains all of the elements 2, 3, and 4.
query.containsAll("arrayKey", [2, 3, 4]);

However, I would like to find objects where the key's array value contains at least one (not necessarily all) of the elements 2,3, and 4.

Is that possible?

Answer 1

I'm not positive, but what happens if you try containedIn?

I think if you pass an array, it checks to see if any are contained.

query.containedIn("arrayKey", [2,3,4]);

I know that if you use equalTo with an array key and a singular value, it checks if the value is in the array and returns TRUE. I think this will do something similar and should work. I think it will check if any value in "arrayKey" is in the passed array. If any key object does, it will return the object.

Answer 2

swift 3.0

let Query:PFQuery = PFQuery(className: “className”)
Query.whereKey(“Field Name”, containedIn: array)// [“1”,”2”,”3”];
