What do you want from Room when you create a DAO method and annotate it with @Delete?

Example:

@Dao

public interface MyDao {

@Delete

public void deleteUsers(User... users);

}

ARoom generates an implementation that inserts all parameters into the database in a single transaction.

BRoom modifies a set of entities, given as parameters, in the database. It uses a query that matches against the primary key of each entity.

CRoom removes a set of entities, given as parameters, from the database. It uses the primary keys to find the entities to delete.
