Find numbers that are missing in second table

Suppose we have a table

declare @Table1 table(id int)
insert into @Table1 
select 1 union all select 2 union all select 3 union all select 4 union all
select 5 union all select 6 union all select 7 union all select 8 

And another table as

declare @Table2 table(id int)
insert into @Table2 
select 1 union all select 2 union all select 5 union all select 8 

We need to find out the numbers that are missing in second table (@Table2)

Solution1:

select id from  @Table1 except select id from  @Table2

Solution2:

select id from  @Table1 where id not in (select id from  @Table2)

Output

id 
3
4
6
7
