RE: [SQL] sum of two queries

От

I use functions.  For example:

Create function1 as'select sum(price) from items';

Create function2 as'select sum(price) from widgets';

select function1 + function2;

Is there a way to return the sum of two separate queries as in:
select (select sum(price) from items) + (select sum(price) fromwidgets))
select 3 + 4 works OK but the parser doesn't like sticking a
subquery inplaceof the numbers.
Is there another way to do this?
