Table 1:
CREATE TABLE BSR_PASSENGER
(PASSENGER_ID INT NOT NULL UNIQUE,
FULL_NAME VARCHAR(30),
COUNTRY VARCHAR(40),
CITY VARCHAR (40),
PRIMARY KEY (PASSENGER_ID));
Table 2:
CREATE TABLE BSR_FLIGHT
(FLIGHT_ID INT NOT NULL UNIQUE,
AIRLINE_NAME VARCHAR(50),
CREW_MEMBERS INT,
PRIMARY KEY (FLIGHT_ID));
Table 3:
CREATE TABLE BSR_BOOKING
(BOOKING_ID INT NOT NULL UNIQUE AUTO_INCREMENT,
PASSENGER_ID INT NOT NULL,
FLIGHT_ID INT NOT NULL,
COST DEC(6,3),
PRIMARY KEY (BOOKING_ID),
FOREIGN KEY (PASSENGER_ID) REFERENCES BSR_PASSENGER(PASSENGER_ID),
FOREIGN KEY (FLIGHT_ID) REFERENCES BSR_FLIGHT(FLIGHT_ID));
Task 6: Add the following record to the OWNER table:
INSERT INTO OWNER VALUES('SA100', 'Sam', 'Afyouni', '100 Hello St', 'Anytown', 'MA', '55555');
CREATE TABLE sales ( SalesNumber INT(10) AUTO_INCREMENT PRIMARY KEY, SalesDate DATE, SalesTotal DECIMAL(10,2));
CREATE TABLE products ( number INT(11) AUTO_INCREMENT PRIMARY KEY, prodid VARCHAR(20) UNIQUE, prodname VARCHAR(30), price DECIMAL(10,2), onhand INT(11), CONSTRAINT fk_salesdetails_products FOREIGN KEY (prodid) REFERENCES salesdetails(prodid) ON DELETE RESTRICT);
CREATE TABLE salesdetails ( number INT(10) AUTO_INCREMENT PRIMARY KEY, SalesNumber INT(10), prodid VARCHAR(20), price DECIMAL(7,2), qty INT(10), CONSTRAINT fk_salesdetails_sales FOREIGN KEY (SalesNumber) REFERENCES sales(SalesNumber) ON DELETE CASCADE, CONSTRAINT fk_salesdetails_products FOREIGN KEY (prodid) REFERENCES products(prodid) ON DELETE CASCADE);
Using the above SQL and the schema diagram, create an ER diagram detailing all the fields of the tables and the relationship amount the tables.
