Now we're using a database from a smartphone. It has a phone_book table. It has the columns id, first_name, last_name and phone. Add a new contact to the phone_book table. Use any valid values you want. All columns are required. The id column is auto incrementing.

INSERT INTO phone_book (id, first_name, last_name, phone) value (NULL, "fdf", "fdf", 4344342);

As Bogdan's example shows, an auto-increment column will be set for you, so you don't need to reference it at all when you insert a new row.

In future, please always provide a link the course page you are working with along with your code to enable the most complete and accurate analysis.

Rostyk/Bogdan's example is missing an "s" at the end of "value", preventing it from running successfully.
