You should be able to just add another output column doing the math... so
for your query:

SELECT STGPOOLS.STGPOOL_NAME, STGPOOLS.MAXSCRATCH,
Count(STGPOOLS.MAXSCRATCH) as "Allocated_SCRATCH",
STGPOOLS.MAXSCRATCH-count(STGPOOLS.MAXSCRATCH) as "Remaining_SCRATCH"
FROM STGPOOLS STGPOOLS, VOLUMES VOLUMES WHERE VOLUMES.STGPOOL_NAME =
STGPOOLS.STGPOOL_NAME AND ((STGPOOLS.DEVCLASS='3592TAPE')) GROUP BY
STGPOOLS.STGPOOL_NAME, STGPOOLS.MAXSCRATCH

Subject: Calculating MaxScratch vs Allocate Volume


When I run the following slect

SELECT STGPOOLS.STGPOOL_NAME, STGPOOLS.MAXSCRATCH,
Count(STGPOOLS.MAXSCRATCH) as "Allocated_SCRATCH" FROM STGPOOLS STGPOOLS,
VOLUMES VOLUMES WHERE VOLUMES.STGPOOL_NAME = STGPOOLS.STGPOOL_NAME AND
((STGPOOLS.DEVCLASS='3592TAPE')) GROUP BY STGPOOLS.STGPOOL_NAME,
STGPOOLS.MAXSCRATCH

I get the following out put

Server STGPOOL_NAME                     MAXSCRATCH
Allocated_SCRATCH
 MSPSTG3 TAPE_APP_BACKUP                 20                     58
 MSPSTG3 TAPE_ARCHIVE                   40                      30
 MSPSTG3 TAPE_ARCHIVE_COPY              80                          39
 MSPSTG3 TAPE_BACKUP_COPY               250                       193
 MSPSTG3 TAPE_DB_BACKUP                 18                          18



My question is how do I subtract "Allocated_SCRATCH Col from the MaxScratch
Col so I can see what the Acutal Scratch Remaining is.  The plan is to have
this be out put to a txt file that can be picked up by our monitoring system
so we can auto genertae a help desk ticket.  I have searched around (here
and the web) and can't seem to find a good example.

Any insight would be great!!!!!!
