The two related table are:

i) Books Table

ii) BOOKAUTHOR Table

The common field between the two tables are:

i) ISBN attribute

The columns that i would like to display are:

Title, ISBN, AuthorID, PubID, PubDate, Cost, Retail, Discount, Category

Sql Code to join tables using where clause

select t1.Title, t1.ISBN, t2.AuthorID, t1.PubID, t1.PubDate, t1.Cost, t1.Retail, t1.Discount, t1.Category from Books t1 INNER JOIN BOOKAUTHOR t2 ON t1.ISBN = t2.ISBN where t1.ISBN = 0401140733

The above query will dispaly the attributes of table "Books" and of table "BOOKAUTHOR" for book ISBN 0401140733

Repeat problem 1 but remove the WHERE statement

After removing the where condition we will have following join query

select t1.Title, t1.ISBN, t2.AuthorID, t1.PubID, t1.PubDate, t1.Cost, t1.Retail, t1.Discount, t1.Category from Books t1 INNER JOIN BOOKAUTHOR t2 ON t1.ISBN = t2.ISBN

The above query will display all the mapping data of table "Books" and of Table "BOOKAUTHOR"

Can someone please tell me what I’m doing wrong ? Please and it’s due on Thursday!!

liberstina [14]

Answer:

Sure. In Unit test 5, it's looking for 1 instead of 0. You are returning 0 instead of 1.

0 requires 1 digit to express it and should therefore return 1.

In line 6, change the 0 to a 1.
