sql server创建临时表的两种写法和删除临时表

--第一种方式

create table #tmp(name varchar(255),id int)

 

--第二种方式

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
