sql插入临时表数据的方法

Posted 2020-09-01 好学的菜鸟

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
