Subject: Re: MS SQL 2005 Express and MySQL on Windows

False hope.  If I fire up irb, require 'dbi', and then try to load a
mysql connection, I get the same error:

> mysql = DBI.connect('dbi:Mysql:.....')
DBI::InterfaceError: Unable to load driver 'Mysql'
...

If I "require 'mysql'", I get "true".  If I then try to load a mysql
connection, I get this interesting error:

> require 'mysql'
true

> mysql = DBI.connect('dbi:Mysql:.....')
DBI::InterfaceError: Could not load driver (uninitialized constant
Mysql:Driver)
	from C:/Program Files/Ruby/lib/ruby/site_ruby/1.8/dbi.rb:344:in
'load_driver'
	from C:/Program Files/Ruby/lib/ruby/site_ruby/1.8/dbi.rb:227:in
'_get_full_driver'
	from C:/Program Files/Ruby/lib/ruby/site_ruby/1.8/dbi.rb:213:in
'connect'

Any other thoughts?  I'm sorry to bombard the list like this...
