sql插入临时表数据的方法

方法有两种，主要看需求。

方法1：定义好临时表的字段和类型、插入对应的值

create table #Tmp --创建临时表#Tmp
(
    City   varchar(50),  --
    Country  varchar(50),   --
);

insert #Tmp
select '北京','中国' union
select '东京','日本' union
select '纽约','美国' 

select * from #Tmp;

 

方法2：直接将查询出来的表数据插入临时表中

if OBJECT_ID('tempdb..#temp') is not null
drop table #temp
select * into #temp from 
(
--select * from Activity
select 7 as 'month',25 as 'day'
    union all
select 7 as 'month',25 as 'day'
    union all
select 8 as 'month',25 as 'day' 
    union all
select 8 as 'month',25 as 'day'
    union all
select 8 as 'month',25 as 'day'

) as A


select *  from #temp
