How do I combine two queries (union all) into one row?

Question

I have a tricky situation in trying to get information from multiple queries into a single row.

Consider the following table:

CpuUage:
    Time    ti         


        

Answer 1

This is a pivot table query. (Search on that if you require further info.)

The query structure you want is something along the lines of the following:

SELECT  groupname,
        SUM(CASE WHEN subsys = 'NORM' THEN jobs ELSE 0 END) AS NormJobs,
        SUM(CASE WHEN subsys = 'NORM' THEN cpu ELSE 0 END) AS NormCpu,
        SUM(CASE WHEN subsys = 'SYS7' THEN jobs ELSE 0 END) AS Sys7Jobs,
        SUM(CASE WHEN subsys = 'SYS7' THEN cpu ELSE 0 END) AS Sys7Cpu,
        SUM(CASE WHEN subsys NOT IN ('NORM', 'SYS7') THEN jobs ELSE 0 END) AS OtherJobs,
        SUM(CASE WHEN subsys NOT IN ('NORM', 'SYS7') THEN cpu ELSE 0 END) AS OtherCpu
FROM    ???
GROUP BY groupname
