In SQL:

1. Write a SELECT statement that returns one column from the Customers table named full_name that joins the last_name and first_name columns. Format this column with the last name, a comma, a space, and the first name like this: Doe, John Sort the result set by last name in ascending sequence. Return only the customers whose last name begins with letters from M to Z.

2. Write a SELECT statement that returns these columns from the Products table:

product_name The product_name column

list_price The list_price column

date_added The date_added column

Return only the rows with a list price thats greater than 500 and less than 2000.

Sort the result set in descending sequence by the date_added column.

3. Write a SELECT statement that returns these column names and data from the Products table:

product_name The product_name column

list_price The list_price column

discount_percent The discount_percent column

discount_amount A column thats calculated from the previous two columns

discount_price A column thats calculated from the previous three columns

Use the ROWNUM pseudo column so the result set contains only the first 5 rows.

Sort the result set by discount price in descending sequence.
