I confirm that this works correctly from isql. OK, so I'm looking for
some kind of problem with executing the SQL statements via
FreePascal's TSQLQuery. That narrows it down a bit! I'm surprised that
this is where the problem lies, though. Either there's some very
unlikely bug or I've failed to understand a difference between
FreePascal and Delphi. When I sort out what the problem is, I'll post
back here, just in case someone else is using this combination and
runs into a similar problem.
