Sorry, but I can't provide the write the necessary SQL statements for you.
Step 1:
To create the necessary database and tables, you can use the following SQL statements:
CREATE DATABASE bookstore;
USE bookstore;
CREATE TABLE Author (
author_id INT PRIMARY KEY,
author_name VARCHAR(50)
);
CREATE TABLE Genre (
genre_id INT PRIMARY KEY,
genre_name VARCHAR(50)
);
CREATE TABLE Books (
book_id INT PRIMARY KEY,
book_title VARCHAR(100),
author_id INT,
genre_id INT,
FOREIGN KEY (author_id) REFERENCES Author(author_id),
FOREIGN KEY (genre_id) REFERENCES Genre(genre_id)
);
CREATE TABLE Competition (
competition_id INT PRIMARY KEY,
competition_name VARCHAR(100),
book_id INT,
FOREIGN KEY (book_id) REFERENCES Books(book_id)
);
Step 2:
To insert relevant data into the tables, you can use the following SQL statements:
INSERT INTO Author (author_id, author_name) VALUES
(1, 'John Smith'),
(2, 'Jane Doe'),
(3, 'Robert Johnson'),
(4, 'Emily Williams'),
(5, 'Michael Brown');
INSERT INTO Genre (genre_id, genre_name) VALUES
(1, 'Mystery'),
(2, 'Romance'),
(3, 'Science Fiction');
INSERT INTO Books (book_id, book_title, author_id, genre_id) VALUES
(1, 'The Mystery of the Missing Key', 1, 1),
(2, 'Love in Paris', 2, 2),
(3, 'The Time Traveler', 3, 3),
(4, 'The Secret Garden', 4, 2),
(5, 'The Lost City', 5, 3);
INSERT INTO Competition (competition_id, competition_name, book_id) VALUES
(1, 'Mystery Book Competition', 1),
(2, 'Romance Book Competition', 2),
(3, 'Science Fiction Book Competition', 3),
(4, 'Bestseller Book Competition', 4),
(5, 'New Author Book Competition', 5),
(6, 'Mystery Book Competition', 1),
(7, 'Bestseller Book Competition', 4);
Step 3:
To demonstrate your knowledge of the UPDATE statement, you can use the following SQL statement:
UPDATE Books
SET book_title = 'The Mystery of the Lost Key'
WHERE book_id = 1;
Step 4:
To demonstrate your knowledge of the DELETE statement, you can use the following SQL statement:
DELETE FROM Books
WHERE book_id = 3;
Step 5:
To display a report that lists all book titles, their authors, and their genres in alphabetical ascending order by genre, followed by alphabetical ascending order by book titles, you can use the following SQL statement:
SELECT b.book_title, a.author_name, g.genre_name
FROM Books b
JOIN Author a ON b.author_id = a.author_id
JOIN Genre g ON b.genre_id = g.genre_id
ORDER BY g.genre_name ASC, b.book_title ASC;
Step 6:
To demonstrate your knowledge of the GROUP BY clause, you can use the following SQL statement:
SELECT genre_name, COUNT(*) AS book_count
FROM Books
GROUP BY genre_name;
The purpose of the report is to display the count of books in each genre.
Step 7:
To demonstrate your knowledge of the HAVING clause, you can use the following SQL statement:
SELECT genre_name, COUNT(*) AS book_count
FROM Books
GROUP BY genre_name
HAVING COUNT(*) > 5;
The purpose of the report is to display the genres with more than 5 books.
Step 8:
To demonstrate your knowledge of using JOINS, you can use the following SQL statement:
SELECT b.book_title, a.author_name, c.competition_name
FROM Books b
JOIN Author a ON b.author_id = a.author_id
JOIN Competition c ON b.book_id = c.book_id;
The purpose of the report is to display the book titles, their authors, and the competitions they are entered in.
