This link might get you a bit further :

http://osdir.com/ml/openoffice.dba.user/2008-06/msg00021.html

and in particular the downloadable zip file referenced there.

However, the Query UI does not, as far as I know, support these
functions, so the only way to access them would be via the SQL query
editor mode, assuming that is, that they are actually recognised in
hsqldb 1.8 (about which I have no idea).
