Not entirely. On which table(s) are the REFERENCES constraints and are
they separate per column constraints or are they multi-column constraints?
It's usually best to cut'n'paste the CREATE TABLE or ALTER TABLE
statements that are used to create the constraints. That way we know
exactly what you're talking about.
