I am a newbie to SQL server and hoping someone can write a single query to replace my manual way of doing the following:
DECLARE @tbl1 table( id int)
INSERT into @tbl1(id)
values(1)
INSERT into @tbl1(id)
values(2)
INSERT into @tbl1(id)
values(3)
DECLARE @tbl2 table( id int, val varchar(1))
INSERT into @tbl2(id,val)
values(1,'A')
INSERT into @tbl2(id,val)
values(1,'B')
INSERT into @tbl2(id,val)
values(2,'A')
INSERT into @tbl2(id,val)
values(3,'A')
INSERT into @tbl2(id,val)
values(3,'B')
INSERT into @tbl2(id,val)
values(3,'C')
SELECT val from @tbl2
WHERE id = 1
INTERSECT
SELECT val from @tbl2
WHERE id = 2
INTERSECT
SELECT val from @tbl2
WHERE id = 3
'A' is return because only A exists in all rows of @tbl1. I would like to avoid using a cursor and dynamic SQL.
Thanks

select b.val
from @tbl1 as a
inner join @tbl2 as b
on a.id = b.id
group by val
having COUNT(val) = (select COUNT(id) from @tbl1)

It takes a minimal capacity for rational thought to see that the corporate 'free press' is a structurally irrational and biased, and extremely violent, system of elite propaganda.

Society has varying and conflicting interests; what is called objectivity is the disguise of one of these interests - that of neutrality. But neutrality is a fiction in an unneutral world. There are victims, there are executioners, and there are bystanders... and the 'objectivity' of the bystander calls for inaction while other heads fall.
