Good day,
I propose to use XPath in DDL to create foreign keys
[1] from rational to xml
create table a(
a1 num,
a2 string
);
create table b(
b1 num,
b2 num references a(@a2/k/m/n/@n1)
);
[2] from xml to rational
create table a (
a1 num,
a2 num
);
create table b (
b1 num,
b2 string
);
alter table b add foreign key (@b2/k/m/n/@n1) references a(a2);
[3] from xml to xml
create table a (
a1 num,
a2 string
);
create table b (
b1 num,
b2 string
);
alter table b add foreign key (@b2/k/m/n/@n1) references a(@a2/p/q/r/@r1);
