Dear Friends,

Postgres 7.3.4 on RH Linux 7.2.

Get the following from the groups
create or replace function ExpensiveDepartments() returns setof table1 as=
=20
'
declare
    r table1%rowtype;
begin
    for r in select departmentid, sum(salary) as totalsalary
        from GetEmployees() group by departmentid loop

        if (r.totalsalary > 70000) then
            r.totalsalary :=3D CAST(r.totalsalary * 1.75 as int8);
        else
            r.totalsalary :=3D CAST(r.totalsalary * 1.5 as int8);
        end if;

        if (r.totalsalary > 100000) then
            return next r.departmentid;
        end if;

    end loop;
    return;
end
'=20
language 'plpgsql';
Is possible for me to return a variable along with that 'return' statement?=
 Because the table 'table1' contains some date
column. I have done some calculation on those columns and want to return th=
e calculated  date along with that row of the
table1. How to do that. Please shed some light.
