方法有两种,主要看需求。

(
    City   varchar(50),  --
    Country  varchar(50),   --
);

insert #Tmp
select 北京,中国 union
select 东京,日本 union

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
