I thought that was the case - but there's no error in the SQL, I can
run this directly on my DB and it works fine.
The main reason I think changes in Pear::DB were at fault was this
exchange:

Good questions ;-) It was the PN module produced by Lawrence Akka
and available here: http://sourceforge.net/projects/pn-modules/
But I believe the previous admin of this site made a few "fixes"...
Lawrence's module was based on 1.3.2 but updated from CVS in Dec2001
Pear::DB reported to be 1.6.2 - just updated it to 1.7.6 on a local
test machine and still get the same error.
I've disabled all the main uses of BackLinks in my Wiki for the time
being but left an error promoting page here:
http://portal.opensta.org/faq.php?topic=BackLinks
Thanks for your response Reini - I didn't really want to bug you with
issues in ancient history, I was just hoping someone would have
already solved this issue.
Cheers
