I’m working with Room database in Android and have three data classes representing my tables:

data class Train(id: Int, isFollow: Boolean)
data class TrainStatus(id: Int, trainId: Int, origin: String, destination: String)
data class PreviousTrain(id: Int, trainStatusId: Int, previousTrainStatusId: Int)

In TrainStatus, trainId is a foreign key that references id from the Train class.

PreviousTrain is a junction table where trainStatusId and previousTrainStatusId are foreign keys referencing id from TrainStatus.

I want to query the database and get a response in the following format:

data class Response(
    val train: Train,
    val trainStatusWithPreviousTrain: List<TrainStatusWithPreviousTrain>
)

data class TrainStatusWithPreviousTrain(
    val trainStatus: TrainStatus, 
    val previousTrain: TrainStatus
)

How can I use the junction table to create a Room query that will give me the data in the Response format?
