Short Answer

Expert verified
Question: Write an SQL statement to create a table named "Book" with columns for publisher name, author name, number of pages, and a 10-character ISBN number. Answer: ```sql CREATE TABLE Book ( publisher_name VARCHAR, author_name VARCHAR, num_pages INTEGER, isbn_number VARCHAR(10) ); ```

Step by step solution

01

Specify the table name

To create a new table, we use the CREATE TABLE statement followed by the name of the table which, in this case, is "Book". ```sql CREATE TABLE Book ( ); ```
02

Add columns and set data types

Now, we need to add the required columns and their corresponding data types into the table. We will use VARCHAR for publisher name, author name, and 10-character ISBN number, and INTEGER for the number of pages. ```sql CREATE TABLE Book ( publisher_name VARCHAR, author_name VARCHAR, num_pages INTEGER, isbn_number VARCHAR(10) ); ```
03

Set primary key (Optional)

Optionally, you can set a primary key for the table, for example, by adding a dedicated "id" column as an INTEGER type and setting it as the PRIMARY KEY. However, this is not explicitly required in the exercise. ```sql CREATE TABLE Book ( id INTEGER PRIMARY KEY, publisher_name VARCHAR, author_name VARCHAR, num_pages INTEGER, isbn_number VARCHAR(10) ); ``` This is the complete SQL statement to create the Book table with the required columns.
