Using the student and faculty tables create a select query that outputs all students for a specific advisor. Generate the execution plan, select out the explain plan. Create an index that allows for a better join between the two tables. Generate and display the revised execution plan. The first line in your script should be to delete all rows from the plan_table so that in the end there are only two plans in the table.
Format:Submit the code to create the tables, insert data, run the select, show the execution plan, create an index and then generate and show the execution plan again. You must submit the code as scripts that the instructor can run from an SQL prompt on an Oracle DBMS. Your submission must include a description of the scripts, their actions, and the order in which they should be run. Your code must not have any "side effects" (that is, it must not do anything not listed in the assignment description, and all of its actions must be described in the program header).
