You lost me...the way I've always seen salts used is just before hashing, but the same salt is used for all the passwords. Then when authenticating passwords, you salt & hash the incoming password and compare to the stored record in the DB. Am I doing it wrong?
Using the same salt for all records makes it significantly easier for someone to crack your whole DB. A different salt for each row means they'd have to go through the effort of creating a rainbow table for each row instead of a whole database.
