in reply to Re^5: perl sql to separate and sort the column separately?
in thread perl sql to separate and sort the column separately?
if 50 jobs were dumped into the queue system in-between runs of the separate queries the results would be quite different.
the sort on the sum seemed to be to list the queues with the largest combined total, but then to sort each sublist by the elements in run/pending separately
For each considered totally separate, if it were me, id just do it all in perl.
