select count(id) as storyNum , sum(convert(numeric(10,2),case when isnumeric(code)=1 then code else 0 end)) as codeNum, sum((case when isnumeric(realcode)=1 then convert(numeric(10,2),realcode) else 0.0 end)) as realcodeNum, tdtname,cycle,jiracomponent,jirastatename,qualityvalue,storycodellt into #tmp from IKNOW_STORY_U2000V1R7C00 group by tdtname,cycle,jiracomponent,jirastatename,qualityvalue,storycodellt 

--查询临时表 
select * from #tmp 

--删除临时表 
if object_id('tempdb..#tmp') is not null begin drop table #tmp end
