I'm trying to dump a manifest of files in the fileset from Postgres to
help achieve my aims above.
I'm trying to work out which tape each file is on, by joining JobMedia
to File. However neither JobMedia.FirstIndex nor JobMedia.StartFile
appear to point to File.FileID.
Can someone point me to the relationship between Media and File?
Thanks
Rory
p.s. My query so far is
SELECT
j.jobid, j.name AS jobname, jmlj.volumename, jmlj.slot, f.fileid,
p.path, fn.name AS filename, f.md5
FROM
job j,
filename fn,
path p,
file f
LEFT JOIN
( SELECT
jj.jobid, jj.mediaid, m.volumename,
m.slot, jj.firstindex, jj.lastindex
FROM
jobmedia jj, media m
WHERE
jj.mediaid = m.mediaid
ORDER BY
jj.jobid, jj.mediaid
) jmlj ON
jmlj.jobid = f.jobid
AND
f.fileid >= jmlj.firstindex
AND
f.fileid <= jmlj.lastindex
WHERE
f.jobid = j.jobid
AND
f.pathid = p.pathid
AND
f.filenameid = fn.filenameid;
