Hi,

I want to create a table where the 2 columns are both primary as well as
foreign key. What is the correct syntax for that?

Thanks

Huub

create table detail
(
id1 integer,
id2 integer,
CONSTRAINT c1 PRIMARY KEY(id1,id2),
CONSTRAINT c2 FOREIGN KEY(id1,id2) REFERENCES master
);

Do you really need such detail table? You can just add columns to master table.
