Hi,

in my first experience with sequel, i installer sqlite3 and sequel gems without problem, then i tried to run the simple example in readme.doc of sequel

require 'rubygems'
require 'sequel'
DB = Sequel.sqlite # memory database

DB.create_table :items do
  primary_key :id
  String :name
  Float :price
end

items = DB[:items] # Create a dataset

# Populate the table

items.insert(:name => 'abc', :price => rand * 100)
items.insert(:name => 'def', :price => rand * 100)
items.insert(:name => 'ghi', :price => rand * 100)

# Print out the number of records
puts "Item count: #{items.count}"

# Print out the average price
puts "The average price is: #{items.avg(:price)}"


without any error the output is:

Item count: 0
The average price is: 
 
someone has info to get it work.
Thanks
