   When using UPDATE, MySQL will not update columns where the new value is the

   of rows matched, only the number of rows that were literally affected by 
   the query.

   The REPLACE statement first deletes the record with the same primary key 
   and then inserts the new record. This function returns the number of 
   deleted records plus the number of inserted records.
