如何使用Room检测UPDATE sql查询成功？

// 实体类
@Entity(tableName = "users")
public class User {
    @PrimaryKey
    public int id;
    public String name;
    public int age;
}

// 数据访问对象（DAO）接口
@Dao
public interface UserDao {
    @Update
    int updateUser(User user);
}

// 数据库类
@Database(entities = {User.class}, version = 1)
public abstract class AppDatabase extends RoomDatabase {
    public abstract UserDao userDao();
}

// 应用程序的主类
public class MainActivity extends AppCompatActivity {
    private AppDatabase appDatabase;
    private UserDao userDao;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 创建数据库实例
        appDatabase = Room.databaseBuilder(getApplicationContext(), AppDatabase.class, "my-database").build();
        userDao = appDatabase.userDao();

        // 创建一个用户对象
        User user = new User();
        user.id = 1;
        user.name = "John";
        user.age = 25;

        // 更新用户信息
        int rowsUpdated = userDao.updateUser(user);

        // 检查更新是否成功
        if (rowsUpdated > 0) {
            Toast.makeText(this, "UPDATE SQL查询成功", Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(this, "UPDATE SQL查询失败", Toast.LENGTH_SHORT).show();
        }
    }
}
