Write SQL and PL/SQL code to answer the questions below. 1. Write an anonymous PL/SQL program block that retrieves information about each employee in the employees table in the Human Resources database and creates a list that displays each employee's names, department name, job title, and phone number in five columns on a single line. The list should be in alphabetical order by last then first name. Print column headings as well as a header above the list identifying it as the "ACME Directory." (Note: Use a CURSOR FOR loop, and the only local variable that needs to be declared is a CURSOR.) 2. Write the code for both a sequence and a trigger that will automatically generate a primary key value whenever a record is added to the product_information table in your personal schema. Also write an INSERT and a SELECT statement that shows that your trigger works
