Question

我的sqlite数据库列定义如下：

  @DatabaseField(canBeNull = true)
  public Date dateFound;

当我打开sqlite broswer时，我发现它的定义如下：

  'dateFound' TIMESTAMP

现在我创建QueryBuilder：

DateTime time=new DateTime();
DateTime minusDays = time.minusDays(4);
QueryBuilder<Record, Long> queryBuilder = DatabaseHelper.get().getRecordDao().queryBuilder();
Where<Record, Long> where = queryBuilder.where();
where.ne("amount",0);
where.or();
where.ge("dateFound",minusDays.toDate());
System.out.println(queryBuilder.prepareStatementString());

输出是：

SELECT * FROM `record` WHERE (`amount` <> 0 OR `dateFound` >= ? )

哪个不正确，我甚至尝试使用new Timestamp(minusDays.toDate().getTime())，结果查询相同..

我通过施放日期来解决它，这可能不是最好的方法，但它的工作：

DateTime time=new DateTime();
DateTime minusDays = time.minusDays(4);
QueryBuilder<Record, Long> queryBuilder = DatabaseHelper.get().getRecordDao().queryBuilder();
Where<Record, Long> where = queryBuilder.where();
where.ne("amount",0);
where.or();
where.raw("cast(`dateFound` as INTEGER)>= "+minusDays.toDate().getTime());
