Rails - May 2006 - handling specific database exceptions

Hi,

When an exception comes from rails, it has a name, i.e:
"AssociationTypeMismatch", so I can catch it like this:

    rescue ActiveRecord::AssociationTypeMismatch => e
    ...
    ...

However, how can I catch and handle specific exceptions that come from
the database. "rescue Exception => e" is not good enough. I want to
be
able to deal with them individually. for example, mysql throws a
duplicate entry key error, how do I catch that in rails?

Thanks,
Alon.

I am trying to figure out if I need to use the database specific error 
codes, but I can''t figure out how to access it from rails...
