"select *" is shorthand for "all columns". You'll note that what's returned isn't some kind of special '*' column, but all columns. The order in which the columns are returned isn't meaningful because the colums have labels -- names -- to tell you which is which. Rearranging the column order doesn't change the answer. "sort by *" would imply that the order of the columns returned by '*' is meaningful, which it is not. "sort by the arbitrary order produced by 'select *'" isn't even deterministic. > So, why make it sound like I don't know what I'm talking about?
