Please, how can I rewrite the rule below so that it works as intended for this
update:
update v set ad=0, bd=0 where ad=1;
As it is now, this will change ad but not bd, presumably because when the
rule's first action has updated ad, the "where ad=1" returns 0 rows for the
second action.
I want this because that is the way MS Access puts data into updates' where
clauses and I want updateable forms on joined tables.
create table a (k integer primary key, ad integer); create table b (k integer primary key, bd integer); create view
vas select a.k, ad, bd from a join b on a.k=b.k; create rule r as on update to v do instead ( update a set
ad=new.adwhere k=old.k; update b set bd=new.bd where k=old.k; );
insert into a values(1,1); insert into a values(2,2); insert into b values(1,1); insert into b values(2,2);
Thank you -- Cornelius
