Just want to throw in an FYI for the row_number()over (order by <columnname>)
Make sure that the columnname (or columnnames) is very unique or you will still see a "hot amping" issue. You just happened to come across
this today and found that the columnname needs to be unique in order to prevent spooling issues caused by "hot amping". A suggestion would be to
use the UNIQUE PRIMARY INDEX column/s as your order by (provided you a have an UPI)or any combination of columns.
