Find the name, grade, and marks of students, in the increasing order of grade.
For Grade 10 we have three students. Now we want these three students to be sorted based on their marks.
In this case, we can specify multiple columns after ORDER BY separated by , to get the result.
Let's reverse the order of columns mentioned in the ORDER BY clause.
Notice the difference in results from the earlier query.
The results are sorted in the order of marks first and then grade.
ORDER BY sorts the result in the order in which the column names are mentioned. So the data is first sorted in the order of the first column in the ORDER BY list, and then in the order of the second column, and so on.
