We mistakenly created a new key as primary key even though we had a perfect candidate key for that.
Now we want to delete that and make the candidate which is already a field on our table the primary key.
Problem we did not want to delete that until is visible via erd.
My question is, can we change a pysical erd to logical one?
We just reverse engineered the database tables and we are using designer 6i.
How can we do that?
thanks
