I have a question that I cannot seem to solve; I don't know if I should post
it here or somewhere else, but here goes.
I have a logbook database which tracks which pages are being accessed on our
site. I would like to know what the pages with the highest "hits" are. Each
time a page is hit, that page's ID # is stored in the database.
I've tried the following
SELECT l1.location, count(l2.location) from logbook l1, logbook l2
where l1.location = l2.location
That was just a guess but of course it didn't work. I've run into this
problem with some related issues; for example, I'd like to be able to give a
particular user a hot link to his/her most referenced page, deducing it in a
simlar way
SELECT u.userid, count(l.location) from logbook l, member u
where l.userid=u.userid
But this doesn't work either. I get an error message: 'Illegal use of
aggregates or non-group column in target list.' I've looked over the
documentation but either I'm going blind or stupid because I just don't get
it. Anyone else solved this one?
Thanks,
Justin Long
