I hope this is the right place to ask this question. I've search the
archives
the news groups and could not find anything so I apologize if this has
been
answered previously
Here is my sample table:
CREATE TABLE master2 (
id int primary key,
name varchar(32),
nickname varchar(32),
unique (name,nickname)
);
This issue is this:
create table reftest2 (
id int primary key,
invited varchar(32),
foreign key (invited) references master2 (name,nickname) on update
cascade on d
elete
cascade
);
This produces the following message:
"ERROR: CREATE TABLE: number of referencing and referenced attributes
for
foreign key disagree"
The idea is that I want to have invited in reftest2 be constrainted
against name
and nickname in the master2 table (actually I really don't want to
"unique
(name,nickname)" in master2, I'd rather have name and nickname be
unique within
themselves if possible)
Is this possible?
