由于找不到列，房间数据库崩溃

Question

当运行从房间数据库查询 return 某些数据时，我在 API 23 物理设备上遇到此崩溃。

我已经检查了 table 和模型，但看不出问题所在。列名明显存在。

TABLE

@Entity (tableName = "tableDistortedThinking")
public class TableDistortedThinking {

@PrimaryKey(autoGenerate = true)
private long pkDistortedThinking;

@ColumnInfo(name = "reframingId")
private long fkReframingId;

@ColumnInfo(name = "userId")
private long fkUserId;

@ColumnInfo(name = "allOrNothing")
private Integer allOrNothing;

型号

public class ModelPieChart {

private long userId;
private String twistedName;
private Integer allOrNothing;
private Date workoutDate;
private int DistortedThinkingCount;

查询

@Query("SELECT TableDistortedThinking.allOrNothing, COUNT(TableDistortedThinking.allOrNothing) AS DistortedThinkingCount, TableDistortedThinking.workoutDate, TableDistortedThinking.userId, TableDistortedNames.distortedName AS twistedName " +
        "FROM TableDistortedThinking " +
        "JOIN TableDistortedNames ON TableDistortedThinking.allOrNothing = TableDistortedNames.pkDistortedNameId " +
        "WHERE TableDistortedThinking.workoutDate >= (1000 * strftime('%s', datetime('now', :dateRange)))" +
        "AND TableDistortedThinking.userId = :userId " +
        "GROUP BY TableDistortedNames.distortedName " +

**他们的查询很长，由 UNION ALL 连接，但只有这一部分真正相关。任何导致此崩溃的帮助根将不胜感激。

此故障是由运行 API 25 或更低设备上发生的 Room 错误引起的。它在房间版本 2.3.0-alpha02 中得到修复。有关详细信息，请参阅 description in the Google IssueTracker。
