Re: Alternative to "Money" ...

That does make more sense (cents? :) ).

View and rule still apply, tho. Better performance still?

create temporary table new_money (product text, cents int4);

create view v_new_money as select product, (cents::numeric/100)::numeric(10,2)
as dollars from new_money;

create rule v_new_money_upd as on update to v_new_money do instead update
new_money set product=new.product, cents=new.dollars * 100 where product =
old.product;

create rule v_new_money_del as on delete to v_new_money do instead delete from
new_money where product = old.product;

create rule v_new_money_ins as on insert to v_new_money do instead insert into
new_money (product, cents) values (new.product, new.dollars * 100);

insert into new_money (product, cents) values ('Flowbee','1995');
insert into new_money (product, cents) values ('Country Hits','995');
insert into v_new_money (product, dollars) values ('ThighMaster','39.95');
update v_new_money set dollars = '14.95' where product='Flowbee';

select * from v_new_money;
   product    | dollars
--------------+---------
 Country Hits |    9.95
 ThighMaster  |   39.95
 Flowbee      |   14.95
(3 rows)

select * from new_money;
   product    | cents
--------------+-------
 Country Hits |   995
 ThighMaster  |  3995
 Flowbee      |  1495
(3 rows)
