Hi, I have an enterprise application that is being developed with MySQL,
but the production app. has to use (for reasons out of my hands) SQL
Server.
Since I upgraded to 1.16, any attempt to run migrate to the production
database (with trace enabled) gets me the following:
W:\holly>rake db:migrate RAILS_ENV=production --trace
(in W:/holly)
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:migrate
rake aborted!
is not a class/module

This looks like an error in ActiveRecord.
Can anyone advise on how I might work around this?
The line 499 in the file dbi.rb reads as follows:
dbd_dr = dr::Driver.new
This strikes me as wrong, as any module or class should begin with an
uppercase character, as I understand it. Or is something really clever
going on here?
Also – updates run fine to MySQL (GOD I wish I could just use that!).
Cheers,
Doug.
