Ok, did that - now it works but returns no records.
What I am after is to reduce the right hand table to one row matching
the left table. There may be no, one or many matching records in the
right table, but I want to group them on the key and find out the number
of records in the right table at the same time.
This works just fine in that other database :-)

Do what it says. Add base.subnetsize to the GROUP BY. You'll
probably
need to add base.descrip, base.baseaddr and base.admingrp as well.
