To delete the book named 'The Case of the Killer Kangaroo' from the database, you could use the following statements:Ĭ. Name='The Case of the Killer Kangaroo', author='Katie Kanga', O author='The Case of the Killer Kangaroo', name='Katie Kanga', Name='The Case of the Killer Kangaroo', author='Jane Doe', What values does the INSERT statement add to the Book table?Īuthor='The Case of the Killer Kangaroo', name='Jane Doe' O this program does not make sure the cursor object is closed Which statement makes sure that the cursor object is closed so its resources are released to the system? Which line opens the connection to the database? execute (query, (name, author, pages, genreID) ) Name = 'The Case of the Killer Kangaroo'Ĭ. I just tested these SQLite foreign key examples on my system, using SQLite version 3.4.0, and they all work fine.Conn = sqlite3. INSERT INTO customers VALUES (null, 'FOOBAR', '200 Foo Way', 'Louisville', 'KY', '40207') INSERT INTO customers VALUES (null, 'ACME, INC.', '101 Main Street', 'Anchorage', 'AK', '99501') INSERT INTO salespeople VALUES (null, 'Barney', 'Rubble', 10.0) INSERT INTO salespeople VALUES (null, 'Fred', 'Flinstone', 10.0) ![]() If you'd like to test this SQLite foreign key example in your own SQLite database, here's some sample data for each of these tables: Next, define a SQLite table that has two foreign keys, one that relates a new orders table back to the customers table, and a second foreign key that relates the orders table back to the salespeople table:įOREIGN KEY(customer_id) REFERENCES customers(id),įOREIGN KEY(salesperson_id) REFERENCES salespeople(id)Īs you can see, the SQLite foreign key syntax is very similar to other databases. To show how this works, first define two database tables that don’t have any foreign keys: Here’s a quick SQLite foreign key example. The SQLite database does support foreign keys, and its foreign key syntax is similar to other databases.
