我有一个SQL语句，如果每个小时都需要我的SUMmations（SQL Server 2008），它可以很好地工作。 DATEPART(HOUR, DATE_TIME)为我做了所有精彩的工作。
SELECT SUM(case STATION_ID when 'S-WELDCHK' then 1 else 0 end) as WELDCHK
,SUM(case STATION_ID when 'S-GLUING-OUT-OK' then 1 else 0 end) as GLUING
,SUM(case STATION_ID when 'S-GLUING-OUT-NOK' then 1 else 0 end) as 'GLUING-NOK'
,SUM(case STATION_ID when 'S-ULTRAWELD-OUT-OK' then 1 else 0 end) as ULTRAWELD
,SUM(case STATION_ID when 'S-ULTRAWELD-OUT-NOK' then 1 else 0 end) as 'ULTRAWELD-NOK'
,SUM(case STATION_ID when 'S-BOLTFAST-OUT-OK' then 1 else 0 end) as BOLTFAST
,SUM(case STATION_ID when 'S-BOLTFAST-OUT-NOK' then 1 else 0 end) as 'BOLTFAST-NOK'
,SUM(case STATION_ID when 'S-MAPVISION-OUT-OK' then 1 else 0 end) as MAPVISION
,SUM(case STATION_ID when 'S-MAPVISION-OUT-NOK' then 1 else 0 end) as 'MAPVISION-NOK'
,SUM(case STATION_ID when 'S-CHECKFIX-OUT-OK' then 1 else 0 end) as CHECKFIX
,SUM(case STATION_ID when 'S-CHECKFIX-OUT-NOK' then 1 else 0 end) as 'CHECKFIX-NOK'
,SUM(case STATION_ID when 'S-EJOT-OUT-OK' then 1 else 0 end) as EJOT
,SUM(case STATION_ID when 'S-EJOT-OUT-NOK' then 1 else 0 end) as 'EJOT-NOK'
FROM [dbFactory].[dbo].[Events]
where (DATEPART(yy,DATE_TIME) = 2014
AND DATEPART(mm,DATE_TIME) = 2
AND DATEPART(dd,DATE_TIME)= 5)
GROUP BY
DATEPART(HOUR, DATE_TIME)
with rollup
我真正想要的是我在临时表中有不规则时间段的SUMS（为简洁而截断）
Start Finish
06:00:00.000 06:30:00.000
06:30:00.000 07:30:00.000
07:30:00.000 08:30:00.000
08:30:00.000 09:30:00.000
09:30:00.000 10:00:00.000
10:00:00.000 10:30:00.000
10:30:00.000 11:30:00.000
11:30:00.000 12:30:00.000
12:30:00.000 13:30:00.000
13:30:00.000 14:00:00.000
网站上的任何建议或我应该阅读的内容以解决此问题。应该有一个工具来汇总用户定义的函数，也许我可以通过START和FINISH期间以及事务的DATE_TIME。
答案 0 :(得分：1)
使用between
inner join Periods on events.DATE_TIME between Periods.Start and Periods.End
并按期间表中的字段分组
group by Periods.Start
NB。如果时间段恰好在两个时期之间的边界上，您需要决定会发生什么。您可能需要调整期间，或使用＆gt;加入和＆lt; =
您可能还想查看PIVOT而不是使用SUM(CASE...构造。
答案 1 :(得分：0)
这就是我获得工作解决方案的方式。它不漂亮或高效。这是目前每24小时运行一次的报告的一部分。
