如何使用Room Dao中的计算字段订购记录

Question

我的实体如下：

@Entity(tableName =  "PupilScore", primaryKeys = ["SubjectId", "PupilId"], indices =
            arrayOf(Index(value = ["SubjectId", "PupilId"], unique = true, name = "idx_PupilScores")))

    data class PupilScore (@NotNull @ColumnInfo(name = "SubjectId") var subjectId: String,
                                @NotNull @ColumnInfo(name = "PupilId") var pupilId: Long = 0,
                                @SerializedName("Score") @ColumnInfo(name = "Score") var score: Int = 0)

我想在PupilScoreDao类中编写一个查询SELECT PupilId, SUM(Score) as TotalScore FROM PupilScore GROUP BY PupilId ORDER BY TotalScore DESC，将查询结果返回为列表

尽管我可以返回列表，但无法返回有序列表。当在OrderBy中使用TotalScore时，Room会给出编译器错误。有什么建议吗？
