I want to do something like this: ALTER TABLE companies ADD CONSTRAINT fk_companies_item_id FOREIGN KEY (item_id, 'Company') REFERENCES item_bases(item_id, item_type) INITIALLY DEFERRED I could add a column to companies that is always set to "Company" but that seems like a waste. I tried the above and I got a syntax error.
Can there be more than one row in "item_bases" with the same "item_id" but different "item_type"s?
