Irrespective of this discussion, a single salt value for all you entries is discouraged. It's better to have one salt value per entry. Some algorithms even embed the salt in the encrypted value itself so that everything is stored in a single column. In an ideal world, you would keep the salts in a separate structure altogether but the embedded salt per entry is a near second in case the whole dataset is being brute forced.
