Referencing partial primary key? Any way to solve it?

    Hi everyone. Is it possible to use REFERENCES to refer part of a primary key? I know it isn't because I already tried. The question is: is there any trick to over rule this kind of situation?

    thanks!

    only if you can put a UNIQUE constraint on that one column of the primary key;

    a foreign key (REFERENCES) can only point to a PK or UQ.
