Write complex or simple SQL queries given a table column and sets of questions


I have a large database table. I cannot send you the table because the data are private but I can send you the column names so that you can write a SQL statements. I need you to be professional freelancer with good SQL experience that can retrieve data fast with time/complexity in mind because the table is huge with 1M+ columns.

The requirement is that we will start with simple SQL over chat to learn your experience, and you are not sending the project to others as a middle man. I want to work directly with you so that we chat and I get immidiate feedback. If you are good at SQL, you should be able to answer simple queries right away. For the work, we will do complex analysis on the 1M+ and gowring dataset.
