Comment:
Another victim here. Just spent several hours with finding this bug, which
had existed several days. This definitely should be either fixed or
prevented: values that the incorrect query provides are often somewhat in
the sensible range, depending on your row structures, which can make this
bug hard to spot.
I also tested both queries that bendavis78 outlined above and they give
correct results. Didn't do extensive performance testing yet, with 20K
rows in the largest table, both queries were between 0.05 and 0.10 secs.
