Hello,
I'm trying to learn to use HaskellDb. I have managed to finally compile and install it on my linux box (I have ghc 6.8.2). But when I try to create a database description (as described in http://haskelldb.sourceforge.net/getting-started.html) (using DBDirect-dynamic instead of DBDirect) I'm stuck. I have tried different names for the driver but
I don't have much information about using DBDynamic, but I am able to connect to PostgreSQL easily. I have done it on Windows using GHC 6.8.2. I am using hdbc-postgresql, since hsql would not compile on Windows for me. Here are the import statements and the login function I have for a simple program that connects to postgresql and writes out table info: import Database.HaskellDB.DBSpec.DatabaseToDBSpec import Database.HaskellDB.DBSpec.DBSpecToDBDirect import Database.HaskellDB.Database import Database.HaskellDB.HDBC.PostgreSQL import Database.HaskellDB.PrimQuery import Database.HaskellDB.FieldType import Database.HaskellDB.DBSpec login :: MonadIO m => String -> Int -> String -> String -> String -> (Database -> m a) -> m a login server port user password dbname = postgresqlConnect [("host", server), ("port", show port), ("user", user), ("password", password), ("dbname", dbname)] The versions of all packages I'm using are: HDBC-1.1.4 HDBC-postgresql-1.1.4.0 haskelldb-hdbc-0.10 haskelldb-hdbc-postgresql-0.10 Note you might have to modify the haskelldb cabal files to get them to use later versions of HDBC. As for recent documentation, unfortunately the darcs repository and the code is the best place to go. The haddock documentation doesn't have everything. Finally, I'd suggest joining the haskell-db users mailing list for specific questions. You can find info about that and the darcs repository on the homepage at http://haskelldb.sourceforge.net. Justin
