John and Dieter,
Thanks for providing insight into how this function works. Based on what you have provided, wouldn't you always want to choose the
primary index of the source table. (assuming you were trying to number rows and not achieve some other result) This would ensure that none
of the data would redistribute during the sort operation. Wouldn't choosing any other combination of columns cause the data to redistribute
during the sort?
Or is the spool file distributed based on the first column provided so if you had a multi-column primary index, it would not matter.
Jim
