Hello everyone,

I will start with the premise of apologiesing for lack of knowledge in this field.

I am a student at a BA master degree and have to attend a DBA subject. I m not into DBA at all so maybe I can find someone here who may help me. I would really appreciate any sort of help :)

Problem:

Given attached 3 SQL scripts and the optimization .txt file which already contains 4 queries, I need 2 or 3 more queries in continuation/parallel with already existent ones (preferrably following same pattern as previous ones if possible).

Can someone please help me out?
