ERROR 1049 (42000): Unknown database

Question

I can\'t seem to login to my tutorial database development environment:

Ayman$ mysql -u blog -p blog_development
Enter password: 
ERROR 1049 (42000): Unknown da         


        

Answer 1

blog_development doesn't exist

You can see this in sql by the 0 rows affected message

create it in mysql with

mysql> create database blog_development

However as you are using rails you should get used to using

$ rake db:create

to do the same task. It will use your database.yml file settings, which should include something like:

development:
  adapter: mysql2
  database: blog_development
  pool: 5

Also become familiar with:

$ rake db:migrate  # Run the database migration
$ rake db:seed     # Run thew seeds file create statements
$ rake db:drop     # Drop the database
