如何使用时间戳列获取两个日期之间的数据？

Question

我有一个下面的查询，它提供了过去 X 天的数据。而不是我想在两个日期之间获取数据，如果可能的话应该可以配置？有什么办法吗？

SELECT processId,
 houroftheday,
 minuteofhour,
 listagg(clientId, ',') within group (order by minuteofhour) as clientIds,
 count(*) as psg
 FROM data.process
 where kite = 'BULLS'
 and code is null
 and timestampinepochsecond > date_part(epoch, sysdate) - X*24*60*60
 group by 1, 2, 3

timestampinepochsecond 列有这个值 - 1599608655

如何使用timestampinepochsecond 列获取两个日期之间的数据？如下所示：

 timestampinepochsecond between 2020-12-01 AND 2021-01-05

更新

我正在尝试声明两个变量并在我的查询中使用它们，如下所示，但它不起作用-

CREATE TEMP TABLE tmp_variables AS SELECT 
   cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-09 16:22:17.897' ) as bigint) AS StartDate, 
   cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-10 16:22:17.897' ) as bigint)      AS EndDate,
   5556::BIGINT       AS some_id;

SELECT StartDate, EndDate FROM tmp_variables;

我认为您必须将日期时间转换为 Epoch Timestamp，然后基于此进行查询：

    -- this will get the the timestamp in seconds
    DECLARE @startTimeStamp bigint = cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-09 16:22:17.897' ) as bigint)

 DECLARE @endTimeStamp bigint = cast(DATEDIFF(s, '1970-01-01 00:00:00.000', '2016-12-10 16:22:17.897' ) as bigint)
    

-- then your query.

SELECT processId,
 houroftheday,
 minuteofhour,
 listagg(clientId, ',') within group (order by minuteofhour) as clientIds,
 count(*) as psg
 FROM data.process
 where kite = 'BULLS'
 and code is null
 and timestampinepochsecond >= @startTimeStamp  AND  timestampinepochsecond 
 < @endTimeStamp
 group by 1, 2, 3

如果这是一个存储过程 - 您可以传入开始日期，结束日期是一个参数 - 然后转换为纪元秒数。
