How can I get data from 2 tables in Realm

Question

I have 2 tables:

Table Question:

questionId, questionContent, chapterId

Table Choice

choiseId, choiceContent, questionId

The input is chapterId so I want to get an array of object that contain all questions and options that matched to that question. I am using Realm database and RxSwift. How can I do this. Thanks you!

Realm is NoSQL database, Joins are not supported. In short, You cannot query on multiple tables using a single query call. Instead, you should use Relationships
