that is a good point, and probably a good reason to use unique values as primary keys. I guess I am slightly confused on database design then. I am working with DNA sequences and they can be quite long strings. So I am using a crc32 to check for uniqueness. Would it still be a good idea to use that as a primary key? I merely assumed that was not an ideal key?
