Hope that helps I don't understand the problem with sub-querying, it seems like it should be just as fast:
code :
    sub.gn as groupname,
    sum(sub.nj) as NormJobs, sum(sun.nc) as NormCpu,
    sum(sub.sj) as Sys7Jobs, sum(sub.sc) as Sys7Cpu
  from (
          groupname as gn,
          sum(jobs) as nj, sum(cpu) as nc,
          0 as sj, 0 as sc
        from tbl
          where subsys = 'NORM'
          group by groupname
        union all select
            groupname as gn,
            0 as nj, 0 as nc,
            sum(jobs) as sj, sum(cpu) as sc
          from tbl
          where subsys = 'SYS7'
          group by groupname
    ) as sub
    group by sub.gn
    order by 1

Can you define values in a SQL statement that you can join/union, but are not stored in a table outside of the statement

This might help you Sure, you can use a UNION ALL inside a subselect and join with the result of that. Something like this might do the trick:
code :
FROM table1 T1
    SELECT titles, stuff 
    FROM table2
    SELECT 'foo' AS titles, 'foostuff' AS stuff
    SELECT 'bar' AS titles, 'barstuff' AS stuff
) T2
ON T1.id = T2.titles

How can I select mysql data with a union statement where the data matches each select statement, i.e. combine the AND op

wish help you to fix your issue Lets say I have a table with just two columns: name and mood. A row holds a persons name, and their mood, if they have multiple moods, then multiple rows are stored in the DB. , Provided you have no duplicates, you can do it with a subquery:
code :
SELECT `name` FROM (
    SELECT `name`, COUNT(*) AS `count` FROM `moods`
    WHERE `mood` IN ('Excited', 'Happy', 'Proud') GROUP BY `name`
) WHERE `count` = 3
SELECT `m1`.`name` FROM `moods` `m1`
JOIN `moods` `m2` USING (`name`)
JOIN `moods` `m3` USING (`name`)
WHERE `m1`.`mood` = 'Excited' AND `m2`.`mood` = 'Happy' AND `m3`.`mood` = 'Proud'
SELECT `name` FROM `moods`
WHERE `mood` IN ('Excited', 'Happy', 'Proud')
GROUP BY `name`
