Hi, I am attempting to get code working that connects to a MS SQL server from a Linux web server. My testing in irb works, but when I try it in rails I have no such luck. Sorry about the long post. I have install and tested FreeTDS (works), and unixODBC (works). I have a working ODBC connector called CTEL. I have also installed RubyDBI and RubyODBC. I tested those by starting irb1.8 and executing the following code: require "dbi" dbh = DBI.connect(''dbi:ODBC:CTEL'', ''usrename'', ''password'') sth = dbh.execute("SELECT Org_ID FROM Org") while row = sth.fetch do print row end sth.finish (Where username and password are the correct values.) It works perfectly and prints out all of the Org_IDs. So, it looks like I have all of the prereqs workings and life is good. However, when I start working in rails things don''t go as smoothly. My database.yml looks like: ctel: adapter: sqlserver mode: odbc dsn: CTEL username: ************ password: ************* My model is legacy_customer.rb: class LegacyCustomer < ActiveRecord::Base establish_connection :ctel set_table_name :Org set_primary_key :Org_ID end Next I open up script/console and type "test = LegacyCustomer.new" and get the following: DBI::DatabaseError: INTERN (0) [RubyODBC]No data found from /usr/local/lib/site_ruby/1.8/DBD/ODBC/ODBC.rb:186:in `[]='' from /usr/local/lib/site_ruby/1.8/dbi/dbi.rb:733:in `[]='' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/sqlserver_adapter.rb:42:in `sqlserver_connection'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/abstract/connection_specification.rb:251:in `send'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/abstract/connection_specification.rb:251:in `connection_without_query_cache='' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/query_cache.rb:54:in `connection='' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/abstract/connection_specification.rb:220:in `retrieve_connection'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/connection_adapters/abstract/connection_specification.rb:78:in `connection'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:696:in `columns'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:1969:in `attributes_from_column_definition'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/base.rb:1351:in `initialize_without_callbacks'' from /usr/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/callbacks.rb:236:in `initialize'' from (irb):1:in `new'' from (irb):1 Any ideas on what I could do from here?

Any body? I still haven''t had much luck resolving this issue, so I would definitely appreciate any suggestions.

If you have text columns that have empty strings this error will occur. It''s a bug in RubyODBC. Make sure that the text columns are either NULL or have some data in them. gnubbs wrote:> Any body?
