I am not sure what minus means, may you illustrate
Try running the query with and without the minus sign, then compare the result sets. it should be pretty clear then what it is doing, though i'm not sure why the chose to demonstrate that here...
Thanks for reaching out.
It simply reverts the order in which your output will be displayed. The null values have precedence.
Hope this helps.
