Page 187 - rake db:migrate

BACKGROUND:

I'm using InstantRails on Windows XP.

Here is my ruby info:
C:\InstantRails\rails_apps\shovell>ruby script/about
About your application's environment
Ruby version 1.8.4 (i386-mswin32)
RubyGems version 0.9.2
Rails version 1.2.2
Active Record version 1.15.2
Action Pack version 1.13.2
Action Web Service version 1.2.2
Action Mailer version 1.3.2
Active Support version 1.4.1
Application root C:/InstantRails/rails_apps/shovell
Environment development
Database adapter mysql
Database schema version 1

=====================================================
PROBLEM:

On page 187, when I do:

rake db:migrate

...the migration does not work.

This is what appears in the development log:

SQL (0.000000) SET SQL_AUTO_IS_NULL=0
SQL (0.000000) Mysql::Error: #42S01Table 'schema_info' already exists: CREATE TABLE schema_info (version int(11))
SQL (0.000000) Mysql::Error: #42S01Table 'schema_info' already exists: CREATE TABLE schema_info (version int(11))

=======================================================

Any ideas?

Thanks.

I deleted the 3 MySQL tables in shovell development, then ran rake and it succeeded, but now I have the tables without any rows.

Here is what happened:

C:\InstantRails\rails_apps\shovell>rake db:migrate
C:0:Warning: require_gem is obsolete. Use gem instead.
(in C:/InstantRails/rails_apps/shovell)
== CreateStories: migrating ===================================================

-> 0.1410s
== CreateStories: migrated (0.1410s) ==========================================

== CreateVotes: migrating =====================================================
-- create_tablevotes)
-> 0.0940s
== CreateVotes: migrated (0.0940s) ============================================

(1) How can I make this work without having to delete tables and recreate rows?

(2) What's the story with this warning message? How can I get rid of it. It occurs frequently.
C:0:Warning: require_gem is obsolete. Use gem instead.

Thanks in advance for any info.
