am trying to do a simple DB connection from Haskell to a SQL Server 2005 (on Windows obviously). The DSN name ("Nylon") works from C++ but when running the below example (or any other I can think of) ghci crashes. Does anyone know a resolution for this or where the problem can possible be ? GHCi, version 6.8.2: http://www.haskell.org/ghc/ :? for help Loading package base ... linking ... done. Prelude> :m Database.HDBC Prelude Database.HDBC> :m + Database.HDBC.ODBC Prelude Database.HDBC Database.HDBC.ODBC> do { conn <- connectODBC "DSN=Nylon"; xs <- getTables conn; putStr $ head xs; } Loading package array-0.1.0.0 ... linking ... done.
