I am trying to get non matching records from 2 tables
For ex
TableA
ID Account
1 Acc1
2 Acc2
3 Acc3
TableB
Opp Accountid
Opp1 1
Opp2 2
Opp3 4
I need to know which accountid which is present in TableB but not available in TableA. It would be wonderful someone could explain how you would approach this query.
Required record would be Opp3 of tableB
Thanks

create table #one (id int,acc nvarchar(25))
insert into #one (id , acc) values(1,'one')
insert into #one (id , acc) values(2,'two')
insert into #one (id , acc) values(3,'three')
create table #two (acct nvarchar(25),ids int)
insert into #two (acct,ids) values('one',1)
insert into #two (acct,ids) values('two',3)
insert into #two (acct,ids) values('four',4)
select ids from #two EXCEPT select id from #one
drop table #one
drop table #two
test this one
