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::
I was able to do this, but not with a simple query :-(
Here's the solution I came up with. Perhaps someone else
knows an easier way to do this?
Using your table (called 'RESULTS' in my example):
test=# select ASMT_CODE,count(*)::float4 as TOTAL into tmp1 from RESULTS
group by ASMT_CODE;
Table t
