Please read careful and provide answers as I need to check with my answers. Please provide a short detail with each answer so if i get it wrong, I know where my mistakes are.I will be attaching the a2.ddl and a2.sql file if needed. Please comment if you require anything else. I will upvote best answers!

In this section, you must edit the file a2.sql and add SQL statements that can be run in psql on Prisnm machines. Your SQL statements can create views and queries that will populate the result tables query1, query2, .., query10 with tuples that satisfy the questions below. In order to ensure that everything is run in the correct order (by the markers or the automarker), you should add all your SQL statements in the file a2.sl that we have provided. This file can be read and executed using the psql command i You can assume that the a2.ddl file has been read and executed in psql, before your a2.sql file is executed. Follow these rules: The output of each query must be stored in a result table. We provide the definitions of these tables in the a2.ddl file (query1, query2,.., query10). . For each of the queries below, your final statement should populate the respective answer table (queryX) with the correct tuples. It should look something like "INSERT INTO queryx (SELECT ...
