排序顺序未被分解

Question

我想做一个简单的查询，我想按日期、小时和分数排序，其中日期和小时来自同一字段 (epoch_seconds)。到目前为止，我已经完成了以下工作：

SELECT cast(epoch_seconds as date) as d, hour(cast(epoch_seconds as time)) as t, score as s
FROM MyTable
order by cast(epoch_seconds as date), hour(cast(epoch_seconds as time)) desc, s asc
limit 10;

我运行遇到的问题是，当有日期时，它似乎按日期和时间排序，使其他排序变得毫无意义（因为它下降到第二个）我通过尝试测试了这个以下，它工作正常。

SELECT TO_DATE('1986-12-11') d, hour(cast(epoch_seconds as time)) as t, score as s
FROM MyTable
order by d, hour(cast(epoch_seconds as time)) desc, s asc
limit 10;

有没有办法在忽略时间的情况下按日期排序？

谢谢

编辑：

为了证明我的理论，我尝试了以下方法

TO_CHAR(cast(epoch_seconds as date))

并显示

2020-09-02 14:53:30.313

所以我在发布后不久就搞清楚了。

它并不漂亮，但它确实有效。

select subStr(TO_CHAR(cast(epoch_seconds as date)),0,10) as d,
       cast(epoch_seconds  as time) as t
From table
order by d, t
