I have the following class:

	emp ( name, ssn, sal,  dno )

I would like to construct a postquel query that would do the following:

find the average salary of employees grouped by `dno'. i.e I would like
to find the average salary in department 1, 2, 3 etc..

The SQL version of this query is:

select  avg(sal)
from emp
group by dno.

Any suggestions ?

Thanks,

-- Niranjan

p.s: postgres version 4.2.
