获取两个日期之间的日期列表

我将使用此存储过程将所需的时间间隔生成到名为 time_intervals 的临时表中，然后进行联接并使用temp
time_intervals 表聚合您的数据表。

该过程可以生成您在其中看到的所有不同类型的间隔：

call make_intervals('2009-01-01 00:00:00','2009-01-10 00:00:00',1,'DAY').select * from time_intervals  .interval_start      interval_end        ------------------- ------------------- 2009-01-01 00:00:00 2009-01-01 23:59:59 2009-01-02 00:00:00 2009-01-02 23:59:59 2009-01-03 00:00:00 2009-01-03 23:59:59 2009-01-04 00:00:00 2009-01-04 23:59:59 2009-01-05 00:00:00 2009-01-05 23:59:59 2009-01-06 00:00:00 2009-01-06 23:59:59 2009-01-07 00:00:00 2009-01-07 23:59:59 2009-01-08 00:00:00 2009-01-08 23:59:59 2009-01-09 00:00:00 2009-01-09 23:59:59 .call make_intervals('2009-01-01 00:00:00','2009-01-01 02:00:00',10,'MINUTE'). select * from time_intervals.  interval_start      interval_end        ------------------- ------------------- 2009-01-01 00:00:00 2009-01-01 00:09:59 2009-01-01 00:10:00 2009-01-01 00:19:59 2009-01-01 00:20:00 2009-01-01 00:29:59 2009-01-01 00:30:00 2009-01-01 00:39:59 2009-01-01 00:40:00 2009-01-01 00:49:59 2009-01-01 00:50:00 2009-01-01 00:59:59 2009-01-01 01:00:00 2009-01-01 01:09:59 2009-01-01 01:10:00 2009-01-01 01:19:59 2009-01-01 01:20:00 2009-01-01 01:29:59 2009-01-01 01:30:00 2009-01-01 01:39:59 2009-01-01 01:40:00 2009-01-01 01:49:59 2009-01-01 01:50:00 2009-01-01 01:59:59 .I specified an interval_start and interval_end so you can aggregate the data timestamps with a "between interval_start and interval_end" type of JOIN..Code for the proc:.-- drop procedure make_intervals.CREATE PROCEDURE make_intervals(startdate timestamp, enddate timestamp, intval integer, unitval varchar(10))BEGIN-- *************************************************************************-- Procedure: make_intervals()--    Author: Ron Savage--      Date: 02/03/2009---- Description:-- This procedure creates a temporary table named time_intervals with the-- interval_start and interval_end fields specifed from the startdate and-- enddate arguments, at intervals of intval (unitval) size.-- *************************************************************************   declare thisDate timestamp;   declare nextDate timestamp;   set thisDate = startdate;   -- *************************************************************************   -- Drop / create the temp table   -- *************************************************************************   drop temporary table if exists time_intervals;   create temporary table if not exists time_intervals      (      interval_start timestamp,      interval_end timestamp      );   -- *************************************************************************   -- Loop through the startdate adding each intval interval until enddate   -- *************************************************************************   repeat      select         case unitval when 'MICROSECOND' then timestampadd(MICROSECOND, intval, thisDate) when 'SECOND'      then timestampadd(SECOND, intval, thisDate) when 'MINUTE'      then timestampadd(MINUTE, intval, thisDate) when 'HOUR'        then timestampadd(HOUR, intval, thisDate) when 'DAY'         then timestampadd(DAY, intval, thisDate) when 'WEEK'        then timestampadd(WEEK, intval, thisDate) when 'MONTH'       then timestampadd(MONTH, intval, thisDate) when 'QUARTER'     then timestampadd(QUARTER, intval, thisDate) when 'YEAR'        then timestampadd(YEAR, intval, thisDate)         end into nextDate;      insert into time_intervals select thisDate, timestampadd(MICROSECOND, -1, nextDate);      set thisDate = nextDate;   until thisDate >= enddate   end repeat; END;

这篇文章底部的类似示例数据场景，我为SQL
Server构建了类似的功能。
