Hi Christopher, I don't know exactly what the "Haskell database interfaces project" is, but here are some developments that you might want to know about: 1) Krasimir Angelov's HSQL toolkit provides (untyped) access to ODBC, MySQL and PostgresSQL databases. It doesn't return meta information yet. <http://htoolkit.sourceforge.net/> 2) wxHaskell has extensive ODBC support (but only tested on windows as yet). also untyped but with meta-information. <http://wxhaskell.sourceforge.net/doc/Graphics.UI.WXCore.Db.html> 3) Haskell/DB is being revived to provide typed access to databases. This is a student project at Chalmers. You can reach them at <dp03-7@mdstud.chalmers.se>, and I think it was Anders Höckersten who is doing it? Now that Haskell has functional dependencies, you can mimick just enough of TREX with nested cartesian products to use HaskellDB without TREX. I think they use HSQL for the low-level access :-( (that is meant funny:-) I hope this helps, Daan.

Hi Christopher,
I don't know exactly what the "Haskell database interfaces project" is, but here are some developments that you might want to know about:
Dominic Steinitz was leading an effort back in Jan/Feb 2003, but it seemed to fizzle out, or at least I never heard about it again.

Typed access, that's exactly it. I'll have to contact the folks at Chalmers. Thank you. Chris ===== Christopher Milton cmiltonperl@yahoo.com
