Answer

It sounds like you just need the name of the person with the highest value Bookingtotal.

You don’t specify your RDBMS, however

select top(1) BookingLastName, BookingFirstName
from bookingxx
order by BookingTotal desc

Your specific database might use limit instead of top; you can also use with ties for where the same total is shared by more than one.
