Avoiding use of a temp table by using sub queries

Question

I want to create a subquery to avoid the use of a temp table. Right now I have:

select id,COUNT (id)as Attempts
into #tmp
from Table1
where State in ('SD')
and Date >=  cast( GETDATE() -7 as date )
group by Accountid having COUNT (accountid) > 2

select *
from #tmp a join Table1 b on a.id= b.id
and b.Date >=  cast( GETDATE() -7 as date )
where CAST(Date as date) = cast(GETDATE()-1 as date)
order by a.id,b.Date 

Is there a way to get this result in just one query?

Answer 1

Replace #tmp in the second query with the first query enclosed in parenthesis, as in:

select *
from (
  select id,COUNT (id) as Attempts
  from Table1
  where State in ('SD')
  and Date >=  cast( GETDATE() -7 as date )
  group by Accountid having COUNT (accountid) > 2
) a join Table1 b on a.id= b.id
and b.Date >=  cast( GETDATE() -7 as date )
where CAST(Date as date) = cast(GETDATE()-1 as date)
order by a.id,b.Date 

The first query becomes a "table expression".
