This doesn't even remotely answer the question... The question here is how to acheive "chained grouping" of "subject" and "semester" at the same time, as explained in the given example...

The last example shows you how to put 2 columns using aggregate function. @ChaitanyaBapat

This doesn't work in Oracle if you have more select column that you don't wan't to group.
