Database query

Hi all!
Im trying to learn ruby :) and I have a problem when changing a hash to
a db table.

I made a hash with a key and value like this:

url = { "1" => "www.url1.com"
"2" => "www.url2.com"
....
}

Then I used it like this:

url.each do |number,url|
 if number == "1"
 ....
else
 ....
end

Now, I made a table in SQLite3 with four columns:
Key - integer
Category - Numeric
Description - Text
Url - Text

This is my little script and it works:

require 'sqlite3'
db = SQLite3::Database.new "test.db"
db.results_as_hash = true
db.execute( "SELECT Key,Url FROM Sites" ) do |site|
  puts "-> Site #%d %s" % [ site['Key'], site['Url'] ]
 end

Now my problem is that I dont know how to use this instead of my hash. I
thought that I could do something like this:

store_as_hash = db.execute( "SELECT Key,Url FROM Sites" )

and then just use this like I did with the hash above but it doesnt
work:

store_as_hash.each do |number,url|
 if number == "1"
 ....
else
 ....
end

I dont know if I can explain my problem in a better way....hopefully you
understand..How can I use the result from the query?
