Subject: Re: SQL statement for multiple classes
Hi Eric,
I was actually trying to something similar with different data and tables a few
weeks ago. With the help of a co-worker, we figured it out. It has to be a 2
step process. First you get a list of all the values you want as the column
headings, in your case, the class name:
select distinct class_name from backups.
Then using that list, you use the class_name in each of the CASE statement
below:
SELECT node_name, -
COUNT ( CASE WHEN class_name = 'CLASS1' THEN class_name END ) AS
CLASS1_COUNT, -
COUNT ( CASE WHEN class_name = 'CLASS2' THEN class_name END ) AS
CLASS2_COUNT - FROM backups - GROUP BY node_name
I put it on multiple lines for readability, you can put it in a single line if
you remove the "-". You can as many "COUNT(CASE..." as you have classes you
want to report on.
Thanks,
Marc...

Subject: [EXTERNAL] [ADSM-L] SQL statement for multiple classes
Hi everybody,
I'm trying to figure out how to create a SQL query to retrieve the amount of
files, per management class, per node in just one query. The ideal output would
be:
Nodename Class1 Class2 Class3
Mynode1 1234 475859 3645895
Mynode2 12345 274368746 8948382348
If you select a count(*) from archives where class_name='CLASS1' you will only
get the amount stored for Class1, so I will have to be able to combine multiple
select count(*) from archives where statements in one single query.
Thank you very much for your help!
Kind regards,
