query

im trying to build a query that has something like this

select
    id,
    (select top 1 create_date from table2 
         where table1id = t1.id 
         and status = 'success') [last_success_date],
    (select count(*) from table2
         where table1id = t1.id
         and create_date > [last_success_date]) [failures_since_success]
from table1 t1

as you can see the [last_Success_Date] is not within the scope of the second query, and i was wondering how i could access that value in other queries without having to rerun it?
