create proc base_proc
as
select * into #huge_result from auths
select * from article, #huge_result where article.author_code=

使用兩個(gè)過程可以得到更好的性能
1)create proc base_proc
as
select *
into #huge_result
from auths
exec select_proc
2) create proc select_proc
as
select * from article,#huge_result
where article.author_code=#huge_result.author_code and sex=”0”
