Re: [Haskell-cafe] Access to Oracle database from Haskell

I had luck with this the other day using Database.HDBC.ODBC. For Ubuntu's Hardy I found that Oracle's 10.2.0.3 worked best. (10.2.0.4 and 11 seemed to have problems for me at least.) http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linu... Grab the basic (not basic-lite), odbc, and sqlplus (to test) zips. The odbc_update_ini.sh should be run from inside the instantclient_10_2 directory as root sudo /bin/sh odbc_update_ini.sh / (assuming a standard unixODBC install.) You'll also need a tnsnames.ora file to describe your connection(s) to the DB(s). You'll also need to define some environment variables to run against all this. I use a small script: #!/bin/sh oracle_home=/opt/lib/oracle/instantclient_10_2 export TNS_ADMIN=$oracle_home export LD_LIBRARY_PATH=$oracle_home [ $# = 0 ] && exit 1 exec "$@" Best of luck, -ljr Steve Lihn wrote:

As Oracle is a commercial company who is not interested in open source historically, it is little chance that you will get robust software for free -- from someone with many years of Oracle DBA experience :-)

Is there a way of accessing a remote Oracle database by one of the common Haskell database interfaces (HaskellDB, Takusen, etc.) ? I tried to get unixODBC and Oracle's Instant Client running on a Linux machine, but I'm trapped in the notorious error:

$ isql USER -v [IM004][unixODBC][Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_HENV failed [ISQL]ERROR: Could not SQLConnect

This error message is discussed in various web forums, but there seems to be no systematic way to track down the problem. So I wonder whether there is another way to access the Oracle data base from Haskell. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
