我有一个查询,该查询的运行计数(timesRaced_byEvent)显示一匹马运行特定事件的次数。我的问题是TimesWon_byEvent,在这里我希望该字段显示特定事件中一匹马获胜(排名第一)的情况的连续计数,但是如您所见,我还不在那里。
select #temp2.Horse
, #temp2.RaceLength
, #temp2.Position
, #temp2.RDIndex
, count(#temp2.RaceLength) over (Partition by #temp2.Horse, #temp2.RaceLength order by #temp2.Horse, #temp2.RaceLength, #temp2.RDIndex desc) - 1 as TimesRaced_byEvent
, TimesWon_ByEvent
from #temp2
Left join
(
Select Horse
, RDIndex
, RaceLength
, count(RaceLength) over (Partition by Horse, RaceLength order by Horse, RaceLength,RDIndex desc) - 1 as TimesWon_ByEvent
from #temp2
where Position = '1'
) win on #temp2.Horse = Win.Horse
and #temp2.RDIndex = Win.RDIndex
and #temp2.RaceLength = Win.RaceLength
order by #temp2.RDIndex
答案 0 :(得分:1)
如果我理解正确,您似乎想要:
select t.*,
(row_number() over (partition by horse, racelength order by rdindex desc) - 1) as timesRacedbyEvent,
sum(case when ur_position = 1 then 1 else 0 end) over (partition by order, racelength order by rdindex desc) as
from #temp2 t;
我对列名有些困惑。您似乎将racelength
等同于“事件”。但这应该可以满足您的要求。
