DBI/DBD for MySQL

Hi there,

I am a bit confused about the installation for DBI/DBD.

  • Is the default build/install of Ruby 1.8.4
    not including the DBI module?
  • If no: Is there no Gem available for DBI?
  • Is the MySQL DBD not part of the Windows
    binary distribution of Ruby 1.8.2? 1.8.4?
  • Is there a way to install the DBD module
    on my laptop where I have no make/gcc/…?

Another question I was asking myself:
When upgrading Ruby, I normally remove and
re-install. Is that the normal way to go?

Thank you for any help

Just in case you want to know why I am asking –
but of course you may stop reading and citing here :wink:

Ruby is installed on both
my Linux server (Ruby 1.8.4, build by me) and on
my Windows laptop (Ruby 1.8.2, binary distribution).

On both system Rails is installed, too;
a Rails application using MySQL is working
on the Windows system. On Linux none yet done.

For a Ruby (not Rails) app I need a connection
to MySQL and would like to use DBI.

On Linux (Ruby 1.8.4) the
require ‘dbi’
fails already, so it looks like dbi is not installed.

On Windows (Ruby 1.8.2) the require seems ok
but when I try the DBI.connect - is ok on the Win laptop (Ruby 1.8.2)

c:/ruby/lib/ruby/site_ruby/1.8/dbi/dbi.rb:499:in load_driver': is not a class/module (TypeError) from c:/ruby/lib/ruby/site_ruby/1.8/dbi/dbi.rb:401: in_get_full_driver’
from c:/ruby/lib/ruby/site_ruby/1.8/dbi/dbi.rb:381:in `connect’
from c:/test/test.rb:5

I would say the DBD for MySQL is not installed.

    It’s not not part of the stdlib. It’s bundled with the one-click
    installer for Windows, though.

  • If no: Is there no Gem available for DBI?
    Not yet.

    Yes, but the underlying driver is not.

    The DBD is just an interface for an underlying driver. You don’t need
    to build dbd-mysql, just install it. It’s a wrapper for
    http://raa.ruby-lang.org/project/mysql-ruby/.

Another question I was asking myself:

re-install. Is that the normal way to go?
That’s what I do.

Thank you. Understood.
Tried the pure Ruby MySQL driver.
Unfortunately my MySQL version’s authentication
is not yet supported by the available module.

On Linux I didn’t try yet, but there I will use
the native driver.
