Task 2 – PL/SQL implementation:

Before you begin please refer to the appendix for initial setup of the database.

1. Populate the tables by writing a procedure that inserts a new record into the database. (The records shown in the appendix can be used). The procedure should:

• Check for reasonable inputs
• Put a new record in the “books” table
• Put a corresponding new record in the “book_copies” table

2. Write a procedure that retrieves a book count.

3. Write a procedure getBookDetails which accepts an isbn number and returns the books title, author, date_published, and  the number of copies. The main block should call the procedure with a isbn number and output the book’s details

4. Write a PL/SQL block which utilises the getBookdetails procedure and prints the data for each record.

5. Write a procedure that deletes a book and all copies from the database.

6. Write a trigger that that reports how many book copies are present after any insert/update/delete operation.
