Create a stored procedure named prc_inv_amounts to update the INV_SUBTOTAL, INV_TAX, and INV_TOTAL. The procedure takes the invoice number as a parameter. The INV_SUBTOTAL is the sum of the LINE_TOTAL amounts for the invoice, the INV_TAX is the product of the INV_SUBTOTAL and the tax rate (8 percent), and the INV_TOTAL is the sum of the INV_SUBTOTAL and the INV_TAX.

Write a SUB Query to display name of the Instrument that are manufactured in USA (country).

Write a stored procedure called sp_apply_discount() that will apply percent discount to books in a subject. The stored procedure takes in 2 parameters, percentDiscount (DECIMAL(8,2)) and subject (VARCHAR(120)). Using these parameters, the stored procedure computes the discount for the book cost and stores it in the FINAL_PRICE field. For example, the following stored procedure call: call sp_apply_discount(0.15, 'Database');would compute 15% percent discount from the book cost in the Database subject category and store it in the FINAL_PRICE column as depicted in this image:

Refer to the film and inventory tables of the Sakila database. The tables in this lab have the same columns and data types but fewer rows. Write a query that lists the titles of films with the fewest rows in the inventory table. This query requires a subquery that computes the minimum of counts by film_id: SELECT MIN(count_film_id) FROM ( SELECT COUNT(film_id) AS count_film_id FROM inventory GROUP BY film_id ) AS temp_table; This subquery is provided in the template.

Write a PL/SQL stored procedure to print number of employees who are working in a job with Title "Tester". Include procedure call also. If the total count of Employees is more than 5 then print "Sufficient number of Employees" If the total count of Employees is less than 5 then print "Insufficient number of Employees" Else print "there are 5 employees". Use Oracle's NO DATA_FOUND build in exception to display the last message.
