sql query into ror query

I want this query into ror form
select name from Batch where id = 1
i want only name
i tried
Batch.find(:all, :conditions => {:id => 1}) it works
but
Batch.find(:name, :conditions => {:id => 1}) not work
please give me suggestion

Batch.where(:id => 1).select(:name)

If you are using Rails 3, you can do

Batch.select(:name).find(1)

I guess you are using Raiils 2.*, in rails 2.x, it should be

Batch.find(:all, :conditions => {:id => 1}, :select => “name”)
