SUBJECT: DBI.Connect I've tried looking on web and cannot get answer. I am getting an error while attempting to connect to various databases using ODBC. Regardless of the database, I get the following error:
DBI::InterfaceError: Unable to load driver 'ODBC' (underlying error: uninitialized constant DBI::DBD::ODBC)
I've created ODBC datasources,and have used these ODBC connections in the past with other languages. However, I cannot get them to work with DBI. I have connected using WIN32OLE.new('ADODB.Connection') with ruby, but I would like to see how DBI works.
Below shows the gems installed and the irb sessions with errors. Can anyone help?
