Rails - Mar 2009 - variable using problem

I have an array A =
[''XXX'',''YYY'',''ZZZ'',''RRR'',''WWW'']
For each element of array I must execute a query on my database.
I don''t want write this code:

A.each {
  |elem|
  case elem
  when ''XXX'' do Model.find(:all,:select =>
''COD'',:group =>
''COD'',:include => :table).map{|el| el.table.XXX}.sort
   .
   .
   .
  end
}

I''d like this:

A.each {
  |elem|
  Model.find(:all,:select => ''COD'',:group =>
''COD'',:include
=> :table).map{|el| el.table.elem}.sort
}

But there''s a problem in this code. Can you help me? Can I write that?
Thank you very much

For a given attribute, some_record[''foo''] gets you the
attribute
value. You might also be interested in the send method.
