Giorgio,
Sounds like (but correct me if I'm wrong) you have a table like:
pieces
--------
hammer
nails
hammer
screws
ruler
If you do a select count(*) on this table and include a group by,
it's just going to give you the statisitcs
hammer 2
nails 1
screws 1
ruler 1
So I'm not really sure what you're asking. Maybe you could give
an example of what is in your table and what you are trying to
get out?
