Thanks, david for your help. The reason for copying records is that I
need to change them to new records, which are exactly the same as the
old records except one column value. The loc_id is the primary key but
it's not really used for searching information. So basically I don't
care about the loc_id as long as they are unique, that 's why i want
it to be random.
