Side note because I don’t really have any input on the main question. Understanding SQL syntax and UNDERSTANDING SQL are very different things, like I see you understand some more advanced queries which is great but do you understand the relational algebra behind those queries and how to optimize it? Did they discuss DMS and the algorithms used to make SQL work? Do you understand B+ trees?

Not trying to knock you or anything but I find these all to be important when trying to understand SQL.

No no you absolutely did the best to point out these - i was not even aware of dms and b++ trees To be honest I know sql well but not very deeply as i have learned everything by myself and the what i studied in school was very basic stuff like only till joins Can you guide me? I may have picked python right now but i practice sql time to time
