Errors in rake db:create

[Tasneem Yusuf]

I have a basic working knowledge about ruby and am trying to now setup
ruby on rails on my personal machine which is a Windows XP machine. The
versions of ruby,gems and rails are below

C:\ruby\Programs>ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

C:\ruby\Programs>rails -v
Rails 2.3.5

C:\ruby\Programs>gem -v
1.3.6
After installing rails and rubygems , I was trying to setup rails for a
first project reading up from
http://guides.rubyonrails.org/getting_started.html

the command
gem install mysql installed one gem and gave me some documentation
related errors which I figured were not a major concern after reading
your ticket 1598 and others.
However when I try to do rake db:create I get the following errors :

C:\rubygems-1.3.6\blog>rake db:create --trace

The gem you installed is just an interface to MySQL. You need to install MySQL as a standalone application as well.

If you have installed MySQL; you need to make sure it is running.

I would recommend using sqlite3 in development, unless you are doing something that requires MySQL or Postgres(trig functions, for example, are in the big RDB's but not sqlite).

@Jeremy Chase

I have installed a Mysql standalone application and is running when I
use the command rake db:create.

For reference I have attached the database.yml file that I have made for
my ruby on rails application.

@Kannav Rajeev

I'm not sure what I need to configure in the database for the RoR
application. Please help.

Thanks

Thanks everyone , it turns out that doing the age-old trick of
re-installing the app has solved this problem.

Thanks,
