Trying to play with haskell/db, I've found myself being a little bit stuck. The latest version of hugs haskell/db (as referenced from http://www.haskell.org/haskellDB/download.html) works with seems to be of May 1999. I cannot find any references to this version of hugs except http://www.cs.uu.nl/~daan/download/hugs98may.exe which is broken. Is it possible to find somewhere in the net all neccessary components (older hugs, newer haskelldb, whatever...) to run any haskelldb example? With best regards and Happy New Year! Kyra

There is a project (of which I am a member) at Chalmers University of Technology that aims to update HaskellDB to work with current versions of GHC and Hugs, and on non-Windows platforms. We have an experimental version that works under Hugs Nov 2003 and GHC 6.2, using a patched version of the HSQL ODBC driver for database access. The code is still incomplete, but we are working on it. We will make an announcement when we feel that the library is in a usable state. Happy New Year, Bjorn Bringert
Hi Kyra,
Trying to play with haskell/db, I've found myself being a little bit stuck.

Sorry for causing this inconvenience - maybe I should remove the webpage... However, haskellDB is fairly old and was also the start of a framework for typeful database programming. It uses the TREX extension though that never has been implemented in GHC and other Haskell systems. Furthermore, Haskell wasn't as good as it is now with foreign libraries. Therefore, I still provide the old Hugs 1998 may version just to enable people to play with it. As Bjorn said, the good news is that people at Chalmers try to update haskellDB for use in current Haskell's -- probably using functional depencies with repeated catesian products to emulate TREX-like functionality. Maybe they can provide you with a prototype version? All the best, Daan.

Unfortunately, http://www.cs.uu.nl/~daan/download/hugs98may.exe is broken (cut at 256k boundary?).

Yes, I'm itching to see it soon. Regards, Kyra
