I'm having some trouble with the group by clause. It seems I can't group
data that has been "cast"ed
First start with:
select cast((bytes/1024/1024/1024) as decimal(8,2)) AS "GB", cast(end_time
as date) as "Date" from summary where activity='STGPOOL BACKUP'
1794.26 2009-10-19
1026.27 2009-10-19
1371.60 2009-10-20
1524.60 2009-10-20
1053.99 2009-10-21
1755.08 2009-10-21
As expected, it shows one line per process. I would like to group these
by the date so we have a total amount of Gigabytes per day.
But when I add the "sum" and "group by" clauses, it doesn't change the
output:
select sum(CAST((bytes/1024/1024/1024) as decimal(8,2))) AS "GB",
cast(end_time as date) as "Date" from summary where activity='STGPOOL
BACKUP' group by end_time
1794.26 2009-10-19
1026.27 2009-10-19
1371.60 2009-10-20
1524.60 2009-10-20
1053.99 2009-10-21
1755.08 2009-10-21
Also, it doesn't let me group by "Date". It needs to be grouped by the
"end_time"
Any ideas to produce what I'm looking for?
TSM 5.5.3 on AIX 6.1

Shawn
