In 7.1 you can frequently replace temp tables with subselect-in-FROM.
Cutting-and-pasting freely from your solution:
select ASMT_CODE, PASSED, TOTAL, PASSED::float4/TOTAL::float4
from
(select ASMT_CODE, count(*) as TOTAL from RESULTS
group by ASMT_CODE) as tmp1
natural join
(select ASMT_CODE, count(*) as PASSED from RESULTS
where STATUS='PASSED' group by ASMT_CODE) as tmp2
(haven't tried this, but it looks right...)
This won't necessarily be a whole lot faster than the solution with
temp tables, but it's nice not to have to worry about dropping the
temp tables afterwards.
