Select s. grade, ''class, sum (s. score) total score, avg (s. score) average score from student s group by s. grade
The result is the columns 3 and 6 in the column. The total score and average score are calculated without using group.
Select ''grade,'' class, sum (s. score) total score, avg (s. score) average score from student s
The result is the 7th column in.
We can see that
Select s. grade, s. clazz class, sum (s. score) total score, avg (s. score) average score from
