Form a field from two fields in a select

Hi.
How can i construct a field from two table fields in
a select clausule.
Something like this:

select (month + " " + year) as date from xxx;

from two fields month and year with they obvious values,
to obtain a string link this:

  102001

and not a number as 2011.

Thank you.
