Need some expert to check the effectiveness of my Query

Question

Hi,
I am learner in Oracle, and i was given the scenario below and was asked to write queries for that. I have written the queries, I want someone to confirm if my queries satisfies the required scenario and gives proper output.
Scenario: You have been employed as the database administrator in a software development team for a Book Store. The Database is built, as is the GUI to run the software and it is your job to implement the required SQL Queries to communicate the Database with the GUI. You will be using the database “Bookstore”; this database is available from INB122 blackboard unit page. The database has the following four tables as shown below. Primary key of each table is underlined.
Publisher(publisherCode, publisherName, publisherCity, publisherState)
Author(authorNumber, authourName, authorFirst)
Book(bookCode, bookTitle, publisherCode, bookType, bookPrice, paperback)
Wrote(bookCode, authorNumber, sequenceNumber)
The Queries needs to be broken into two components. The first involves the development of SQL queries that you will test directly against the database. These will serve as the basis for the second component which will involve modifying the original queries to allow for non-static fields/conditions.
For example, if the Query was to list all the books that are a set price (say $30), you would have
SELECT bookTitle FROM Book WHERE bookPrice = 30;
Here the price ($30) is something that the non-static GUI will be allowed to vary and
consequently would take the form:
SELECT bookTitle FROM Book WHERE bookPrice = ?;
Question 1:
--List the titles of all Books that are in a given price range, which are a given book type
--and are printed by given publisher.
--Part 1 Test Case = $40 - $60, HOR, Gale
SELECT bookTitle from book b, publisher p
WHERE b.publisherCode = p.publisherCode
AND b.bookPrice BETWEEN 40 AND 60
AND b.bookType = 'HOR'
AND p.publisherName = 'Gale';
SELECT bookTitle from book b, publisher p
WHERE b.publisherCode = p.publisherCode
AND b.bookPrice BETWEEN &minpricerange AND &maxpricerange
AND b.bookType = '&bookType'
AND p.publisherName = '&publisherName';
Question 2:
--List the titles of all Books that are in a given price range, which are written by a given
--author and are printed by a given publisher.
--Part 1 Test Case = $20 - $30, Smith, 'Batman Books'
SELECT bookTitle from book b, author a, wrote w, publisher p
WHERE b.bookcode = w.bookCode
AND w.authorNumber = a.authorNumber
AND b.publishercode = p.publisher code
AND b.bookPrice BETWEEN 40 AND 60
AND a.authourName = 'Smith'
AND p.publishername= 'Batman Books';
SELECT bookTitle from book b, author a, wrote w, publisher p
WHERE b.bookcode = w.bookCode
AND w.authorNumber = a.authorNumber
AND b.publishercode = p.publishercode
AND b.bookPrice BETWEEN &minpricerange AND &maxpricerange
AND a.authourName = '&authorname'
AND p.publishername= '&publishername';
Question 3:
--List the titles of all Books that are a certain book type, which are written by a given
--author and are printed by a given publisher.
--Part 1 Test Case = ART, Smith, 'Batman Books'
SELECT bookTitle from book b, wrote w, author a, publisher p
WHERE b.bookcode = w.bookcode
AND w.authornumber = a.authornumber
AND b.publishercode = p.publishercode
AND b.bookType = 'ART'
AND a.authourName = 'Smith'
AND p.publishername= 'Batman Books';
SELECT bookTitle from book b, wrote w, author a, publisher p
WHERE b.bookcode = w.bookcode
AND w.authornumber = a.authornumber
AND b.publishercode = p.publishercode
AND b.bookType = '&bookType'
AND a.authourName = '&authourName'
AND p.publishername= '&publishername';

I have written the queries, I want someone to confirm if my queries satisfies the required scenario and gives proper output.Called "testing" - and we shouldn't be testing homework.
Your queries look fine, but since you haven't provided any CREATE TABLE and particularly
INSERT INTO TableName VALUES...
Scenario: You have been employed... <snipetty snip>In future, if asking such questions, please provide such statements with
tested data - i.e. the INSERT's will work.
Oh and BTW, this is a volunteer forum - messages marked "Urgent" are a breach
of etiquette.
