Name for server connection:
cop4710
Host server:
cop4710-postgresql.cs.fiu.edu
Database Name: spr19_FIUusername
Username: spr19_FIUusername

13. Create a database (1) Create table Primary key and Foreign key
Constraints:
NOT NULL
UNIQUE
CHECK Boolean expression
For instance CHECK (price>0)
(4) PRIMARY KEY
(5) FOREIGN KEY
CREATE TABLE products (
product_no integer PRIMARY KEY,
name text NOT NULL,
price numeric );
Primary key and Foreign key
CREATE TABLE order_items (
product_no integer REFERENCES products,
order_id integer REFERENCES orders,
quantity integer,
PRIMARY KEY (product_no, order_id),
CONSTRAINT cq CHECK (quantity > 5) );

14. Create a database (2) Foreign Key CREATE TABLE other_table (
c1 integer PRIMARY KEY,
c2 integer );
CREATE TABLE t1 (
a integer PRIMARY KEY,
b integer,
c integer,
FOREIGN KEY (b, c) REFERENCES other_table (c1, c2) );

15. Create a database (3) CREATE TABLE products (
product_no integer PRIMARY KEY,
name text,
price numeric );
CREATE TABLE orders(
order_id integer PRIMARY KEY,
shipping_address text, …
CREATE TABLE order_items (
product_no integer REFERENCES products ON DELETE RESTRICT,
order_id integer REFERENCES orders ON DELETE CASCADE,
quantity integer,
PRIMARY KEY (product_no, order_id)

16. Create a database (4) Insert Data
INSERT INTO products (product_no , name ,price) VALUES (1,'cheese',5);
INSERT INTO products VALUES
(1,'cheese',5),
(2,’cake’,10) ;

17. Create a database (5) Import Data Export Data
COPY country FROM '/usr1/proj/bray/sql/country_data.csv'
WITH DELIMITER ',' ;
COPY country TO '/sql/country_data.csv' WITH DELIMITER '|';

18. Create a database (6) ALTER Table Add columns Remove columns
Add constraints
ALTER TABLE products ADD COLUMN description text;
ALTER TABLE products DROP COLUMN description;
ALTER TABLE products ADD CONSTRAINT namecheck CHECK (name <> '');
ALTER TABLE products ADD CONSTRAINT some_name UNIQUE (product_no);
ALTER TABLE products ADD FOREIGN KEY (product_group_id)
REFERENCES product_groups;
ALTER TABLE products ALTER COLUMN product_no SET NOT NULL;

19. Create a database (7) ALTER Table Remove constraints
Change column data types
Rename columns
Rename tables
ALTER TABLE products DROP CONSTRAINT some_name;
ALTER TABLE products ALTER COLUMN product_no DROP NOT NULL;
ALTER TABLE products ALTER COLUMN price TYPE numeric(10,2);
ALTER TABLE products RENAME COLUMN product_no TO product_number;
ALTER TABLE products RENAME TO items;

20. Create a database (8) Delete Data
DELETE FROM products WHERE price = 10;
DELETE FROM products
