Explanation / Answer

Hi Dear,

Since you have not posted data for the table. I have wrriten query according to question.

Create a view named Under_100. It consists of the item_id, title, artist, unit_price and order_qty for every print with a unit_price under 100 dollars.

CREATE VIEW Under_100 AS

SELECT items.item_id, title, artist, unit_price, order_qty

FROM items, orderline

WHERE items.item_id = orderline.item_id

AND unit_price < 100.00;

Create a view named Allen. It consists of the customer_id, customer_name, customer_phone, title, and artist of each print ordered.

CREATE VIEW Allen AS

SELECT customers.customer_id, customer_name, customer_phone, title, artist

FROM customers, items, orderline, orders

WHERE customers.customer_id = orders.customer_id

AND orders.order_id = orderline.order_id

AND orderline.item_id = items.item_id;

4. Create a view named zip_27. It consists of the customer_name, customer_phone, title, artist

and date_shipped of each print ordered by a customer whose zip code begins with 27. */

CREATE VIEW zip_27 AS

SELECT customer_name, customer_phone, title, artist, ship_date

FROM customers, items, orders, orderline

WHERE customers.customer_id = orders.customer_id

AND orders.order_id = orderline.order_id

AND orderline.item_id = items.item_id

AND customer_zip LIKE '27%';

5. Create the following indexes. Use the indicated index name.

DEBUG COMMAND: SHOW INDEX FROM insert_name_of_column;

CREATE INDEX customer_id

ON customers (customer_id);

CREATE INDEX name

ON customers (customer_name);

CREATE INDEX shipped

ON orders (customer_id , ship_date);

Drop the name index.

DROP INDEX name ON customers;

   Specify the integrity constraint that the unit_price

of any print must be more than $35.

ALTER TABLE items

ADD CHECK (unit_price > 35.00);

. Ensure that the following are foreign keys

(that is, specify referential integrity) within the prints database.

/* A - customer_id is a foreign key in the orders table. */

ALTER TABLE items;

/* B - Item_id is a foreign key in the orderline table. */

ALTER TABLE items;

Add to the items table a new character field named type that is one character in length.

ALTER TABLE items

ADD TYPE CHARACTER(1);

/* . Change the type field in the items table to M for the print titled Skies Above. */

UPDATE items

SET TYPE='M'

WHERE title = 'Skies Above';

/*   Change the length of the artist field in the items table to 30. */

ALTER TABLE items

CHANGE COLUMN artist TO CHARACTER(30);

What command would you use to delete the orders table from the prints database?

(Do not delete the orders table.)

DROP TABLE orders;
