Issues with schema.rb

Hi all,

I have some doubts in running test cases for a ROR application.
If I create the test DB structure manually and run the individual
tests , they are working fine.
But when I use rails_rake and run all the tests together , the DB is
is getting dropped all together and the tables are generated from
schema.rb.
One problem with this is that the db:migrate is not setting the
primary key and the autoincrement parameters for the table.

I tried to set the primary key and autoincrement parameters in
schema.rb. But it fails .

  create_table "ebooks", :id => false, :force =>
true , :primary_key=”ebook_id” , :options => "auto_increment = 10000"
