I'm trying to use Haskell (version 6.10.3) and HDBC to connect to a MySQL Database. I've chosen to do it with Haskell ODBC. I've used cabal to install HDBC (2.1.1) and HDBC-ODBC (2.1.0.0). I've downloaded and installed the MySQL ODBC driver (5.1.5). I used macports to install unixODBC (2.2.14_1). All of this on top of Mac OS X (10.5.8).
I've mostly been using the instructions on this page http://en.wikibooks.org/wiki/Haskell/Database. At around this point:
"# Add the mysql driver to odbcinst.ini file (under $ODBC_HOME/etc/) and your data source in $HOME/.odbc.ini."
It looks like the macports version of unixODBC installs everything under /opt/local/. I've put an odbcinst.ini into /opt/local/etc/ and I've created a .odbc.ini in my home directory which looks something like this (note that I've experimented with UID vs. USERNAME and PWD vs PASSWORD):
[ODBC Data Sources]myodbc = MySQL ODBC 5.1 Driver[ODBC]Trace = 0TraceAutoStop = 0TraceFile =TraceLibrary =[myodbc]Driver = /usr/local/lib/libmyodbc5.soDATABASE = [hidden]DESCRIPTION = [hidden]SERVER = localhostPORT = 3306UID = [hidden]PWD = [hidden]PASSWORD = [hidden]USER = [hidden]
And I've written and compiled this Haskell Program:
import Database.HDBC.ODBCimport Database.HDBCimport Systemmain = do args <- getArgs c <- connectODBC (args!!0) tables <- getTables c mapM_ putStrLn $ tables
When I try a DSN of "DSN=myodbc" it errors out with:
Database: SqlError {seState = "[\"HY000\"]", seNativeError = -1, seErrorMsg = "connectODBC/sqlDriverConnect: [\"1045: [unixODBC][MySQL][ODBC 5.1 Driver]Access denied for user 'jamie'@'localhost' (using password: YES)\"]"}However, when I try a DSN of "DSN=myodbc;UID=[hidden];PWD=[hidden]", it lists all the tables in the database.
