How to get array with clear data from Active Record query without using map

Hi I would like to ask if its possible get array with clear data from ActiveRecord query without using map, collect or each.

names = User.find(:all, :select => "name")
return names == [#<User name:"Peter">,#<User name:"Martin">]

and I want names开发者_运维技巧 == ["Peter", "Martin"] without using map, collect or each. Thanks for your answers.

User.connection.select_values("SELECT name FROM users")
#=> ["francois"]

Even if ActiveRecord provided a method to do what you want (single column to array of values), it would internally use a loop (each or collect) to do it.

I don't see what is so wrong with using a loop in this case, Ruby makes it quite easy to do it.

users = User.find(:all, :select => "name").collect { |u| u.name }

No you can't do that w/o using map, collect each ... etc......

In otherwords you can't get result like this in a single query.
