Sorry, wrong select
Why does this one not give the correct answer?
Select library_name, count(*) from libvolumes where status='Scratch' group
by library_name

Hi folks,
I am not that good with select queries yes, so I will have to ask one of the
SQL gurus here: we wanted to show how many scratch tapes each library has
with a query like
this:
"select a.library_name,count(*) as volumes, b.devtype from libvolumes as a,
devclasses as b where upper(status) like 'SCRATCH%' and a.library_name='$i'
and a.library_name=b.library_name group by a.library_name,b.devtype"
$i will be filled with the name of the library before. The funny thing, it
shows exactly as twice as many scratches. Is there someone amongst you who
can exctract this little monster for me and show me what I am doing wrong.
Thanks for helping out
Lars
