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(),  --
    Country  varchar(),   --
);

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  as 'month', as 'day'
    union all
    select  as 'month', as 'day'
    union all
    select  as 'month', as 'day'
    union all
    select  as 'month', as 'day'
    union all
    select  as 'month', as 'day'

) as A

select *  from #temp
