You may also be interested to look at:
Database transactions in a purely declarative logic programming language.

It is available from:

under the "related papers" heading.
It describes the Mercury/ODBC interface. I haven't read it properly myself,
but I know that it does use Mercury's nondeterminism as a fairly central
feature. This might mean that the scheme isn't relevant, but it might be
interesting to model this use of nondeterminism in Haskell using a (list or
set) monad. Perhaps Fergus could comment more, as I see he is one of the
authors.
